MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires only network access to an exposed Oracle WebLogic Server WLS Web Services endpoint over HTTP; per the CVSS vector (AV:N/AC:L/PR:N/UI:N) there are no authentication, user-interaction, or special-configuration prerequisites, so default deployments with reachable web-service endpoints are exploitable. The practical limiting factors are therefore network exposure of the web-services ports/context paths and running one of the affected versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0); instances where the Web Services component is undeployed or the endpoints are unreachable from the attacker's network are not exposed. Impact is confined to confidentiality (data disclosure) - integrity and availability are not affected. |
| Impact | The signals point to a genuine high priority rather than a paper-high score: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N combines network reachability, low complexity, no privileges and no user interaction, meaning any exposed WebLogic web-service endpoint is trivially reachable, and the scope change (S:C) plus confirmed high confidentiality impact means a compromise can reach data in other connected products. The offsetting factor is that impact is confidentiality-only (I:N/A:N) - this is a data-exposure/authentication-bypass issue, not remote code execution or denial-of-service. No EPSS score, KEV listing, or POC was provided, so exploitation probability cannot be quantified and there is no evidence of active exploitation; however, WebLogic is a perennial, heavily targeted attacker favorite, so weaponization historically follows Critical Patch Update disclosure quickly. The 'Authentication Bypass' tag aligns with PR:N in the vector, so the available signals are internally consistent. |
| Exploit ScenarioDerived | An attacker who can reach a WebLogic web-service endpoint over HTTP sends a crafted request to the WLS Web Services component without any credentials, bypassing authentication to read sensitive data the server can access. Because of the scope change, the attacker may reach critical data belonging to other products integrated with the WebLogic instance. No public exploit is identified at time of analysis, but the low attack complexity makes reliable exploitation likely once technical details emerge. |

Alert meAnalysisAIv1 – Jul 21, 2026
Unauthorized data disclosure in Oracle WebLogic Server (WLS Web Services component) lets an unauthenticated remote attacker read all data accessible to the server over HTTP, with a scope change that can significantly impact additional products beyond WebLogic itself. Affected supported versions are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0, addressed in Oracle's July 2026 Critical Patch Update. Rated CVSS 3.1 8.6 (confidentiality-only) and tagged as an authentication bypass; no public exploit identified at time of analysis.
RemediationAI
Apply the fixes from Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html) to all affected releases - 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 - as the primary and only fully effective remedy; Oracle distributes these as quarterly patch bundles per version rather than a single upgrade target, so select the patch matching your installed release (Patch available per vendor advisory; no standalone fix version was provided in the input beyond the CPU reference). Until patched, reduce exposure by restricting network access to the WebLogic web-services HTTP/HTTPS ports so they are not reachable from untrusted networks, and where web-service endpoints are not required, undeploy or disable them or filter the relevant URL paths (for example /ws, /wls-wsat and other web-service context roots) at a reverse proxy or WAF - noting that blocking these paths will break any legitimate SOAP clients that depend on them. Place WebLogic behind an authenticating gateway and monitor for anomalous web-service requests as a detective control.

Technical ContextAI · show details
Oracle WebLogic Server is a Java EE/Jakarta EE application server widely used to host enterprise web applications and SOA/web-service endpoints. The flaw resides in the WLS Web Services subsystem, which exposes SOAP/XML HTTP endpoints; the 'Authentication Bypass' tag combined with the unauthenticated network vector is consistent with historically recurring WebLogic issues where web-service handlers process attacker input prior to or without enforcing authentication (frequently insecure deserialization or XML external-entity/SSRF-style handling in the T3/HTTP web-service stack). No CWE was assigned in the source data, so the precise root-cause class cannot be confirmed; the CPE cpe:2.3:a:oracle_corporation:oracle_weblogic_server identifies the affected product but does not narrow the exact web-service handler.

DescriptionCVE.org
Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: WLS - Web Services). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. While the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data. CVSS 3.1 Base Score 8.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).
Executive ViewAI
A critical Oracle WebLogic Server vulnerability allows unauthenticated remote attackers to exfiltrate all data accessible to the server, affecting enterprise middleware deployments globally. The vulnerability's scope extends beyond WebLogic itself to dependent applications and systems, creating organization-wide data exposure risk. No patch is currently available, requiring immediate defensive action.
No vendor-released patch identified at time of analysis. Interim mitigations include: implement firewall rules to restrict HTTP network access to affected WebLogic servers; deploy Web Application Firewall rules to block malicious requests to the WLS Web Services component; disable the WLS Web Services component entirely if not required for active business operations; segment WebLogic servers from critical systems to limit data exposure scope; implement monitoring and alerting on data access patterns and unusual HTTP requests to detect exploitation attempts.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
