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 WebEx Meetings Server is installedLocate the installation directory or check system services for WebEx Meetings Server components. Typical paths include /opt/webex or check service listings (systemctl list-units | grep -i webex or similar).Affected if The product is not installed or has been removed entirely.
-
Identify the installed versionCheck the version of Cisco WebEx Meetings Server using the administrative interface, CLI (show version), or configuration files in the installation directory. Compare against the affected version 2.6.0.Affected if The installed version is exactly 2.6.0.
-
Locate the account-validation endpointIdentify if the /account-validation or similar endpoint exists in the web application. Check the URL paths exposed by the server (typically under /webex/ or /meetings/ paths).Affected if The account-validation endpoint exists and is accessible.
-
Verify remote accessibility of the endpointAttempt to access the account-validation endpoint from an unauthorized remote system. If the endpoint responds without requiring authentication, it is exposed.Affected if The endpoint is reachable from remote networks without authentication.
If Cisco WebEx Meetings Server version 2.6.0 is running with the account-validation endpoint exposed to network access, the environment is affected by this vulnerability.

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 for CSCuy92704. If no patch is available, implement rate limiting or request throttling on the account-validation endpoint to prevent repeated access abuse.
