Cisco Catalyst Sd Wan Manager
Monthly
Remote availability disruption in Cisco Catalyst SD-WAN Manager and Controller allows a low-privileged authenticated attacker over the network to cause high-availability impact with scope change - affecting resources beyond the directly targeted component. Discovered internally by Cisco's SD-WAN engineering team during a proactive security review and addressed in software hardening releases, this vulnerability is not confirmed as actively exploited (not in CISA KEV) and no public exploit code is known at time of analysis. The CVSS 7.7 (High) score reflects the combination of network accessibility, low authentication bar, no user interaction required, and high availability consequence with scope change.
Cleartext storage of sensitive information in Cisco Catalyst SD-WAN Controller and Manager exposes credentials or other security-critical data to authenticated network-accessible attackers, with CVSS 8.8 reflecting the high potential for full system compromise via stolen credentials. Affecting an extraordinarily wide version range spanning 17.2.x through 20.14.x across both the Controller and Manager components, this vulnerability was discovered internally by Cisco's engineering team - a positive signal indicating no known prior adversarial exploitation. No public exploit code exists and the vulnerability is not listed in CISA KEV; however, the SD-WAN control plane sensitivity means exposed credentials could enable broad network infrastructure takeover.
Privileged file manipulation in Cisco Catalyst SD-WAN Manager and SD-WAN Controller allows an authenticated attacker to abuse improper symbolic-link resolution (CWE-59) to read, overwrite, or destroy files outside intended boundaries, with a scope-changing impact that reaches beyond the vulnerable process. The flaw was found during Cisco's internal SD-WAN security review and remediated in hardening releases; it carries a CVSS 9.1 rating driven by network reach, low complexity, and high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the high base score and management-plane exposure make it a meaningful patching priority.
Privilege escalation and cross-boundary information disclosure in Cisco Catalyst SD-WAN Manager and SD-WAN Controller stems from improper input validation (CWE-20) discovered during Cisco's internal hardening review; an authenticated attacker with low privileges can send crafted input over the network to break out of their intended authorization scope and compromise the confidentiality, integrity, and availability of the management plane. The CVSS 9.9 score is driven by a scope change (S:C), meaning impact extends beyond the vulnerable component to the broader SD-WAN control fabric it orchestrates. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the near-maximal CVSS and the centrality of the affected controllers make this a high-priority patch.
Cleartext credential exposure in Cisco Catalyst SD-WAN Manager's web-based management interface allows an authenticated low-privileged remote attacker to read sensitive authentication material from system logs. The root cause is an incomplete encryption allowlist: specific template types are excluded from the encryption policy, resulting in sensitive values being written to logs in cleartext - accessible both on the local system and on any configured remote logging server. No public exploit code has been identified and this vulnerability is not listed in CISA KEV, but successful exploitation directly enables credential theft that can cascade into broader SD-WAN infrastructure compromise.
Privilege escalation and authentication-boundary bypass in Cisco Catalyst SD-WAN Manager and SD-WAN Controller allows a low-privileged, remote authenticated attacker to abuse improper access-control checks (CWE-284) to reach functionality or data intended for higher-privileged roles, with full confidentiality, integrity, and availability impact (CVSS 9.9, scope changed). The flaw was discovered internally by Cisco during a proactive hardening review and shipped as part of a consolidated software-hardening release; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Because SD-WAN Manager is the central orchestration plane for an entire SD-WAN fabric, successful abuse can cascade beyond the compromised component to the managed network.
Arbitrary file write via path traversal in Cisco Catalyst SD-WAN Manager (formerly SD-WAN vManage) allows an authenticated low-privileged attacker to create or overwrite any file on the underlying operating system by sending crafted HTTP requests to affected API endpoints. The vulnerability stems from insufficient validation of user-supplied input during the file upload process (CWE-22), and a successful exploit can serve as a reliable stepping stone to root-level privilege escalation on the management host. No public exploit has been identified at time of analysis, and the vulnerability is not currently listed in CISA KEV; however, the integrity impact combined with root escalation potential elevates real-world risk above the CVSS 6.5 Medium baseline.
Local privilege escalation in Cisco Catalyst SD-WAN Manager (formerly SD-WAN vManage) allows an authenticated netadmin user to execute arbitrary commands as root by uploading a crafted file through the CLI. Cisco has observed limited real-world exploitation that resulted in unauthorized configuration changes being pushed to downstream edge devices, though the issue is not currently listed in CISA KEV and no public exploit code has been identified at time of analysis.
Remote file disclosure in Cisco Catalyst SD-WAN Manager allows unauthenticated attackers to read arbitrary system files via XML External Entity (XXE) injection in the web UI. The vulnerability affects the management interface with network-accessible attack vector, low complexity, and no required privileges (CVSS 8.6). Attackers can extract sensitive configuration files, credentials, and operational data from the SD-WAN management platform. EPSS data not provided; exploitation status unknown but the unauthenticated remote vector and publicly disclosed Cisco advisory elevate real-world risk for internet-exposed instances.
Cisco Catalyst SD-WAN Manager web UI fails to properly redact sensitive information in device configurations and templates, allowing authenticated users with read-only permissions to extract and leverage privileged credentials to escalate their access and modify system configurations. The vulnerability affects all versions of the product and requires only network access and valid (albeit minimal) read-only credentials; successful exploitation grants attackers high-privileged administrative capability over the SD-WAN fabric.
Privilege escalation in Cisco Catalyst SD-WAN Manager allows authenticated users with read-only permissions to elevate privileges to high-privileged user level through exposure of sensitive session information in audit logs. An attacker with initial read-only access can extract high-privilege session credentials from audit logs and impersonate an administrator, bypassing intended access controls. CVSS score 5.4 (medium) reflects the requirement for initial authentication, though the ease of escalation (AC:L) and direct path to administrative capability represent significant risk in multi-tenant or shared SD-WAN deployments.
Remote unauthenticated attackers can bypass peering authentication in Cisco Catalyst SD-WAN Controller (vSmart) and SD-WAN Manager (vManage) to obtain administrative privileges and manipulate network configurations across the entire SD-WAN fabric. This critical authentication bypass (CVSS 10.0) allows direct NETCONF access as a high-privileged internal user without any credentials. Cisco released fixes in May 2026 following discovery of this second authentication flaw after a February 2026 disclosure of a related vulnerability. No active exploitation confirmed in CISA KEV at time of analysis, though the maximum CVSS score and authentication bypass nature make this a priority patching target for SD-WAN deployments.
Cisco Catalyst SD-WAN Manager's web interface contains a reflected cross-site scripting (XSS) vulnerability that requires user interaction and authentication to exploit. An attacker can craft a malicious link to execute arbitrary JavaScript in a victim's browser session, potentially stealing sensitive information or performing unauthorized actions within the management interface. No patch is currently available.
