Tomcat

Cluster-communication confidentiality and integrity in Apache Tomcat can be undermined because the secure-configuration requirements for the EncryptInterceptor were never clearly documented, leaving operators liable to deploy the cluster session-replication channel insecurely. The flaw affects Tomcat 7.0.100-7.0.109, 8.5.38-8.5.100, 9.0.13-9.0.119, 10.1.0-M1-10.1.56 and 11.0.0-M1-11.0.23, and is fixed in 9.0.120, 10.1.57 and 11.0.24. It carries a CVSS 9.1 (C:H/I:H) but SSVC records exploitation as none, no public exploit identified at time of analysis, and the root cause is a documentation weakness (CWE-1059) rather than a code defect.

Security constraint bypass in Apache Tomcat (8.5.0-8.5.100, 9.0.0.M1-9.0.119, 10.1.0-M1-10.1.56, 11.0.0-M1-11.0.23) lets remote attackers reach protected resources by abusing improperly handled hex URL encoding in the RewriteValve, defeating URL-pattern security constraints. Because the flaw resides in the rewrite valve, only deployments that use the RewriteValve together with security constraints are exposed, but where present an unauthenticated attacker (per CVSS PR:N) can access or manipulate resources meant to be restricted. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; EPSS data was not provided.

Path traversal via the COAR Notify / Linked Data Notifications (LDN) service in DSpace 8.0-8.3 and 9.0-9.2 allows an authenticated DSpace administrator to reference arbitrary filesystem paths as LDN inbound-pattern templates, causing those files to be read and interpreted as Apache Velocity templates. While no public exploit or active exploitation has been identified, the vulnerability was demonstrated as part of a proven attack chain in which an administrator stages a malicious Velocity payload in a predictable file location and triggers its execution, enabling either sensitive file disclosure or arbitrary Java code execution via Velocity template injection. No special conditions (KEV, public PoC) are confirmed at time of analysis.

Local file inclusion in DSpace's OAI-ORE Ingestion Crosswalk allows a collection administrator to expose arbitrary server-side files as ingested bitstreams by supplying or triggering a malicious ORE XML document referencing file:/// URIs. Versions 7.x through 7.6.6, 8.0-8.3, and 9.0-9.2 are confirmed affected; fixed releases (7.6.7, 8.4, 9.3, 10.0) are available per the GitHub security advisory. No public exploit and no CISA KEV listing exist at time of analysis; the CVSS score of 4.4 reflects meaningful constraints on exploitation (high privileges, high complexity).

Path traversal in DSpace's Curation Task reporter parameter exposes authenticated Collection, Community, and Site Administrators to file write operations at arbitrary server-side paths writable by the DSpace/Tomcat OS user. Affected are DSpace versions through 7.6.6, 8.0-8.3, and 9.0-9.2, where the attack surface widened when web UI access was granted to admin roles beyond CLI-only system administrators. No public exploit or CISA KEV listing exists; the vendor-assigned CVSS 3.1 score of 5.5 (PR:H, A:H) correctly reflects that high-privilege credentials are required but the availability impact from overwriting configuration or binary files can be severe.

Remote code execution in DSpace 8.0-8.3 and 9.0-9.2 allows an authenticated administrator to execute arbitrary Java via Velocity templates used to render COAR Notify/LDN messages, using reflection to escape the templating sandbox. Exploitation requires valid DSpace administrator credentials and is most impactful when chained with the related LDN path-traversal flaw (GHSA-9qm4-rh6w-pq5x). No public exploit identified at time of analysis, and CVSS is 8.0 (High).

Path traversal in XWiki running on Jetty 12+ lets remote users read arbitrary files the Jetty process can access by sending doubly URL-encoded '../' sequences to the skin resource endpoint (e.g. /xwiki/bin/skin/..%252f/..). Depending on how deep the webapp sits below root, this exposes both in-webapp secrets such as WEB-INF/xwiki.cfg and Hibernate configuration, and out-of-webapp OS files like /etc/passwd. No public exploit or active exploitation is tracked, but the vendor advisory (GHSA-qj4x-9g63-25g6) itself publishes working request URLs, so weaponization is trivial.

Authentication bypass in Apache Tomcat (7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.100, 10.1.0-M1-10.1.36, 11.0.0-M1-11.0.4) lets remote attackers authenticate without supplying the correct password when the JNDIRealm is configured to validate credentials via GSSAPI bind. The flaw (CWE-304, Missing Critical Step in Authentication) means the realm accepts a bind as successful even when the password verification step is effectively skipped. There is no public exploit identified at time of analysis, EPSS risk is low (0.21%, 12th percentile), and it is not listed in CISA KEV.

Improper Authorization (CWE-285) in Apache Tomcat's default servlet allows HTTP method-based and method-omission security constraints to be silently bypassed across all major supported Tomcat branches from 7.0.x through 11.0.x. An attacker can perform HTTP operations - such as PUT or DELETE - that the web.xml security constraint configuration was intended to restrict, potentially enabling unauthorized file upload, modification, or deletion on the default servlet's served content. No active exploitation has been confirmed (not in CISA KEV) and no CVSS score has been published at time of analysis, but the broad version range and ubiquitous deployment footprint of Tomcat make prompt patching a priority.

Replay attack vulnerability in Apache Tomcat's cluster EncryptionInterceptor allows a network-adjacent attacker to retransmit previously captured encrypted inter-node cluster messages, causing receiving nodes to accept and process them as legitimate - potentially corrupting distributed session state or triggering unintended cluster actions. All major supported branches are affected: 11.0.0-M1 through 11.0.22, 10.1.0-M1 through 10.1.55, 9.0.13 through 9.0.18, plus end-of-life branches 8.5.38-8.5.100 and 7.0.100-7.0.109. No public exploit or CISA KEV listing has been identified at time of analysis; however, the breadth of affected versions across all active and legacy branches elevates organizational exposure, particularly for environments running EOL 8.5.x or 7.x with no available patch.

Incomplete security-constraint logging in Apache Tomcat (8.5.0-8.5.100, 9.0.0.M1-9.0.118, 10.1.0-M1-10.1.55, 11.0.0-M1-11.0.22) omits special roles and empty authorization constraints when the effective web.xml is written to the log, giving administrators an inaccurate view of the deployed access-control configuration. There is no public exploit identified at time of analysis, EPSS is low (0.17%, 7th percentile), and CISA SSVC marks exploitation status as none, despite the inflated 9.1 CVSS published by Apache. The practical effect is misleading audit/diagnostic output rather than direct attacker compromise.

Improper handling of a Certificate Revocation List (CRL) error condition in Apache Tomcat's FFM-based (Foreign Function & Memory / OpenSSL) connector allows revoked client certificates to be accepted during mutual TLS authentication, defeating revocation checking. The flaw affects Tomcat 9.0.83-9.0.118, 10.1.0-M7-10.1.55, and 11.0.0-M1-11.0.22 when a CRL is configured on the FFM connector, letting an attacker holding a revoked-but-otherwise-valid client certificate reach protected resources. There is no public exploit identified at time of analysis and the issue is not on CISA KEV, though the CVSS base score is 9.1 (CWE-390).

Access-control bypass in Apache Tomcat's RewriteValve (versions 8.5.0-8.5.100, 9.0.0.M1-9.0.118, 10.1.0-M1-10.1.55, and 11.0.0-M1-11.0.22) arises because once the first condition in an OR (`[OR]`) chain matched, subsequent non-OR conditions were never evaluated. Where operators rely on chained rewrite conditions to gate or restrict requests, an attacker can satisfy only the first condition and have later guard conditions silently skipped, leading to information disclosure or unintended request routing. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; Apache has released fixes in 11.0.23, 10.1.56, and 9.0.119.

Reflected XSS in Apache Tomcat's bundled 'number guess' example application exposes users of that demo page to script injection across all major Tomcat release lines from 7.0 through 11.0. The flaw resides in a sample JSP/servlet, not the core Tomcat runtime, meaning exploitation depends entirely on the example application being deployed and accessible - a configuration that violates standard production hardening guidance. No public exploit code or active exploitation has been identified at time of analysis; no CVSS vector was assigned by the reporter.

Arbitrary file write in GeoServer's Master Password Dump web page allows an authenticated administrator to write attacker-controlled content to any absolute filesystem path the GeoServer process can write to, including JSP files in a Tomcat webapps directory. Because GeoServer enforces no maximum master password length, an admin can embed malicious JSP code into the master password and dump it to an executable location, escalating to remote code execution on the host. No public exploit identified at time of analysis and the issue is not in CISA KEV.

Unbounded memory allocation and CPU exhaustion in OpenTelemetry Java SDK's baggage propagation allows remote unauthenticated attackers to degrade or deny service by sending oversized baggage headers. Affected components - W3CBaggagePropagator, JaegerPropagator, and OtTracePropagator - all lacked enforcement of the W3C Baggage specification's recommended size and entry limits, causing character-by-character parsing of arbitrarily large inputs. A distinctive amplification risk exists: baggage is automatically re-injected into all outgoing requests, meaning a single malicious inbound payload can fan out DoS effects to downstream services that never directly received the original request. No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV.

Unauthenticated Solr streaming expression injection in Goobi viewer Core (versions 4.8.0 through 26.04) allows remote attackers to fully read, modify, or delete the backend Solr index by posting arbitrary expressions to the `/api/v1/index/stream` endpoint. No public exploit identified at time of analysis, but the vulnerability is trivially exploitable with CVSS 9.8 and bypasses access-condition protections such as moving walls and licence restrictions. EPSS is currently low (0.04%) reflecting the niche audience rather than technical difficulty.

efw4.X is an Enterprise Framework for Web. Prior to 4.08.010, efw.file.FileManager.unZip writes zip entries to disk using new File(baseDir, zipEntry.getName()) with no canonical-path check. An entry name such as ../../../pwned.jsp escapes the intended extraction directory and lands anywhere the Tomcat process can write - including the servlet context root. Combined with the framework's multipart /uploadServlet and an event that calls file.saveUploadFiles + FileManager.unZip, a remote attacker with no credentials drops a JSP webshell and executes arbitrary commands as the Tomcat user. This vulnerability is fixed in 4.08.010.

Improper Authorization vulnerability when multiple method constraints define an HTTP method for the same extension in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.

Timing side-channel in Apache Tomcat's AJP secret comparison exposes the shared AJP connector secret to remote, unauthenticated attackers capable of making precise network timing measurements. The vulnerability, tracked as CWE-208 (Observable Timing Discrepancy), affects all major Tomcat branches from 7.0.0 through current releases prior to the fixed versions, and could allow an attacker to recover the AJP shared secret through repeated probing. No public exploit code exists at time of analysis, EPSS is 0.02%, and CISA SSVC rates exploitation as none - making real-world risk low despite the network-accessible attack vector.

Improper Handling of Case Sensitivity vulnerability in LockOutRealm in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Older unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.

DEPRECATED: Authentication Bypass Issues vulnerability in digest authentication in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from before 7.0.0. Older unsupported versions any also be affect Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.

Improper Input Validation vulnerability in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 10.0.0-M1 through 10.0.27. Older, end of support versions may also be affected. Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.

Information disclosure in Apache Tomcat versions 7.0.83 through 11.0.21 exposes HTTP authentication headers to unintended hosts during WebSocket authentication handshakes, enabling credential leakage to third-party endpoints. The flaw carries a CVSS 7.3 score with partial confidentiality, integrity, and availability impact, and no public exploit identified at time of analysis. EPSS probability is very low (0.03%) but SSVC marks the issue as automatable, indicating that scripted exploitation is feasible if attacker positioning is achieved.

Denial of service in Apache Tomcat 9.x, 10.1.x, and 11.0.x allows remote unauthenticated attackers to exhaust server resources due to missing limits or throttling on a resource allocation path (CWE-770). Affected versions span 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, and 9.0.0.M1 through 9.0.117, with older unsupported branches also implicated per the EUVD entry. No public exploit identified at time of analysis, and the EPSS score is very low (0.02%, 5th percentile), but the SSVC framework flags the issue as automatable with partial technical impact.

Server-side template injection in OpenMRS Core allows authenticated users with 'Manage Concepts' privilege to execute arbitrary Java code by injecting malicious Apache Velocity templates into concept reference range criteria fields. The vulnerability stems from unsafe VelocityEngine initialization without sandbox restrictions (no SecureUberspector), enabling unrestricted Java reflection. Exploitation persists across all facility users whenever observations are validated against the compromised concept, creating a persistent remote code execution vector. Fixed in versions 2.7.9 and 2.8.6 via migration from Velocity to sandboxed Spring Expression Language (SpEL) with SimpleEvaluationContext. No active exploitation confirmed (not in CISA KEV), but proof-of-concept details available from researcher advisory at machinespirits.com.

Path traversal (Zip Slip) vulnerability in OpenMRS Core ≤ 2.7.8 and 2.8.0-2.8.5 allows authenticated administrators to achieve remote code execution by uploading a malicious .omod module archive to the REST API endpoint POST /openmrs/ws/rest/v1/module. Attackers can write arbitrary JSP files to the Tomcat webroot via crafted ZIP entries containing directory traversal sequences (e.g., web/module/../../../../malicious.jsp), which bypass incomplete path validation in WebModuleUtil.startModule(). The vulnerability also bypasses the module.allow_web_admin security control, as the REST API does not enforce this restriction despite Legacy UI being protected. No vendor-released patch identified at time of analysis for either affected version range.

Path traversal in OpenMRS Core's ModuleResourcesServlet allows unauthenticated attackers to read arbitrary files from the server filesystem, including sensitive configuration files and system files like /etc/passwd. The vulnerability exists in versions ≤ 2.7.8 and 2.8.0-2.8.5, with exploitation requiring Apache Tomcat < 8.5.31 where path parameter bypass protections are absent. Fix available in version 2.8.6 for the 2.8.x branch; no patch released for 2.7.x series at time of analysis. CVSS 7.5 (High) reflects network-accessible unauthenticated exploitation with high confidentiality impact.

CLIENT_CERT authentication bypass in Apache Tomcat allows unauthenticated remote attackers to bypass certificate-based authentication when soft fail is disabled and Foreign Function Memory (FFM) is enabled, affecting Tomcat 9.0.92-9.0.116, 10.1.22-10.1.53, and 11.0.0-M14-11.0.20. The vulnerability has a CVSS score of 6.5 with high confidentiality impact and partial integrity impact; however, the EPSS score of 0.04% (11th percentile) indicates very low real-world exploitation probability, and no public exploit code or confirmed active exploitation has been identified.

Apache Tomcat's cloud membership clustering component logs Kubernetes bearer tokens in plaintext, enabling unauthenticated remote attackers to extract authentication credentials from log files. Affects Tomcat 9.0.13-9.0.116, 10.1.0-M1-10.1.53, and 11.0.0-M1-11.0.20. CVSS 7.5 (High) reflects confidentiality impact; no public exploit identified at time of analysis. Exploitation requires network access to log files or log aggregation systems, potentially enabling privilege escalation within Kubernetes clusters.

Encryption bypass in Apache Tomcat 11.0.20, 10.1.53, and 9.0.116 allows unauthenticated remote attackers to circumvent the EncryptInterceptor component, exposing sensitive data in cleartext. The vulnerability stems from an incomplete fix for CVE-2026-29146, enabling network-accessible adversaries to access confidential information without authentication. CVSS 7.5 (High severity) reflects network-based exploitation with low complexity and high confidentiality impact. No public exploit identified at time of analysis; low observed exploitation activity (EPSS <1%).

Information disclosure in Apache Tomcat's JsonAccessLogValve allows unauthenticated remote attackers to retrieve sensitive data due to improper output encoding. Affects Tomcat versions 11.0.0-M1 through 11.0.20, 10.1.0-M1 through 10.1.53, and 9.0.40 through 9.0.116. The vulnerability enables high-impact confidentiality breaches through network-accessible attack vectors with low complexity and no user interaction required. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).

Improper input validation in Apache Tomcat allows remote unauthenticated attackers to obtain sensitive information via an incomplete fix of the prior CVE-2025-66614 vulnerability. Affected versions include Tomcat 11.0.15-11.0.19, 10.1.50-10.1.52, and 9.0.113-9.0.115. The CVSS score of 5.3 reflects low confidentiality impact with no integrity or availability impact, and the 0.04% EPSS score indicates minimal real-world exploitation probability at time of analysis with no public exploit code or KEV status confirmed.

Padding oracle attack in Apache Tomcat EncryptInterceptor leaks encrypted session data confidentiality across versions 7.0.100-7.0.109, 8.5.38-8.5.100, 9.0.13-9.0.115, 10.0.0-M1-10.1.52, and 11.0.0-M1-11.0.18 when default configuration is deployed. Unauthenticated remote attackers exploit oracle responses to decrypt sensitive information without authentication (CVSS:3.1 AV:N/AC:L/PR:N). CWE-209 (information exposure through error messages) enables cryptographic side-channel extraction. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.02%).

Authentication bypass in Apache Tomcat 9.x through 11.x and Tomcat Native 1.1.23-2.0.13 allows unauthenticated remote attackers to bypass CLIENT_CERT authentication when soft-fail is disabled, achieving unauthorized access to confidentiality- and integrity-sensitive resources. Exploitation requires no user interaction or privileges (CVSS:3.1 PR:N/UI:N). The flaw affects CLIENT_CERT authentication logic, permitting access under conditions where authentication should fail. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.04%).

Cipher preference order enforcement failure in Apache Tomcat 9.0.114-9.0.115, 10.1.51-10.1.52, and 11.0.16-11.0.18 allows unauthenticated remote attackers to force selection of weaker cryptographic ciphers during TLS negotiation, enabling potential decryption of confidential data transmitted over HTTPS connections. The vulnerability stems from improper preservation of administrator-configured cipher suite priority, potentially exposing sensitive session data, credentials, or application content. No public exploit identified at time of analysis. CVSS 7.5 (High) reflects network-accessible confidentiality impact requiring no privileges.

Open redirect vulnerability in Apache Tomcat's LoadBalancerDrainingValve allows unauthenticated remote attackers to redirect users to untrusted sites via crafted URLs. Affects Tomcat 11.0.0-M1 through 11.0.18, 10.1.0-M1 through 10.1.52, 9.0.0.M23 through 9.0.115, and 8.5.30 through 8.5.100. The vulnerability requires user interaction (clicking a malicious link) and has low real-world exploitation probability (EPSS 0.01%), with no public exploit code or confirmed active exploitation identified at the time of analysis.

HTTP request smuggling in Apache Tomcat 7.x through 11.x permits unauthenticated remote attackers to manipulate request routing and bypass security controls via malformed chunk extension processing. Exploitation enables header injection, cache poisoning, and request routing manipulation without code execution. Affects Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.115, 10.1.0-M1-10.1.52, and 11.0.0-M1-11.0.18. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).

Remote code execution in OpenIdentityPlatform OpenAM 16.0.5 and earlier allows unauthenticated attackers to execute arbitrary OS commands via unsafe Java deserialization of the jato.clientSession HTTP parameter. This bypass exploits an unpatched deserialization sink in JATO's ClientSession.deserializeAttributes() that was overlooked when CVE-2021-35464 was mitigated. Attackers can target any JATO ViewBean endpoint with <jato:form> tags (commonly found in password reset pages) using a PriorityQue

Server-side template injection in OpenOlat e-learning platform versions prior to 19.1.31, 20.1.18, and 20.2.5 enables authenticated users with Author role to execute arbitrary operating system commands via crafted Velocity directives in reminder email templates. Exploitation requires low-privilege authentication (PR:L) but is network-accessible (AV:N) with low complexity (AC:L), achieving full system compromise (C:H/I:H/A:H). The vulnerability leverages Java reflection through Velocity templates to instantiate ProcessBuilder and execute commands with Tomcat process privileges, often root in containerized environments. EPSS data not provided; no CISA KEV status confirmed; publicly available exploit code exists per GitHub security advisory disclosure.

Critical hardcoded credentials vulnerability in ZKTeco ZKBioSecurity 3.0's bundled Apache Tomcat server that allows unauthenticated remote attackers to upload malicious WAR files and execute arbitrary code with SYSTEM privileges.
