Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Cisco ACS installationIdentify whether Cisco Secure Access Control System is installed in your environment by checking for the ACS application directory, services, or by querying installed software on relevant serversAffected if The product is present and running
-
Locate the ACS web interfaceIdentify the URL and port used to access the Cisco ACS Administration and View pages (typically ports 443 or 8080 for the web-based management interface)Affected if The ACS web management interface is accessible
-
Inspect Administration page for anti-CSRF protectionAccess the Cisco ACS Administration page, log in, then view the page source or intercept requests to examine if anti-CSRF tokens are included in HTML forms or session cookiesAffected if No anti-CSRF tokens are present in form submissions to the Administration page
-
Check SameSite cookie configurationInspect the session cookies returned by the ACS web interface using browser developer tools or a packet capture to verify if SameSite attributes are setAffected if SameSite cookie attributes are not configured on ACS session cookies
-
Verify Referer/Origin header validationSubmit a request to the Administration page with a modified or missing Referer/Origin header using a tool like Burp Suite to test if the request is still processedAffected if The application accepts requests without proper Referer or Origin header validation
If Cisco Secure Access Control System is deployed with its web interface accessible and no anti-CSRF protections are implemented on the Administration and View pages, the environment is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch from Cisco for this vulnerability. Additionally, implement anti-CSRF tokens, SameSite cookie attributes, and origin/referer header validation on affected pages as defense-in-depth measures.
