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.
-
Identify Cisco TelePresence Advanced Media Gateway installationLocate the device or software on your network. This is typically dedicated hardware or a virtual appliance. Check network scans or asset inventory for 'Cisco TelePresence Advanced Media Gateway' or 'AMG' entries.Affected if The device or software is present in your environment.
-
Determine the installed software versionAccess the device administrative interface or check system information. The web interface typically shows version in 'System' > 'About' or similar. CLI access may use 'show version' or 'show system information' commands.Affected if The installed version is exactly 1.1(1.40).
-
Verify the web administrative interface is exposedDetermine if the web-based management interface (typically HTTPS on port 443 or 8443) is accessible from network segments where users or attackers could trigger malicious requests.Affected if The web interface is accessible and authentication sessions can be obtained.
-
Inspect for CSRF protectionsExamine HTTP responses from the web interface for anti-CSRF tokens in forms, SameSite cookie attributes, and check if POST requests properly validate Origin or Referer headers before processing state-changing operations.Affected if No CSRF tokens exist in forms, SameSite cookies are not set, and Origin/Referer headers are not validated.
You are affected if Cisco TelePresence Advanced Media Gateway version 1.1(1.40) is deployed with its web administrative interface accessible and no CSRF protections are implemented.

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 dataUpgrade to a patched software version if available; alternatively, implement CSRF tokens, SameSite cookie attributes, and Origin/Referer header validation on all state-changing operations, and disable unused administrative interfaces.
