Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Cross-site request forgery (CSRF) vulnerability in Cisco WebEx Training Center allows remote attackers to hijack the authentication of unspecified victims via unknown vectors, aka Bug ID CSCul25567.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Cross-site request forgery (CSRF) vulnerability in Cisco WebEx Training Center allows remote attackers to hijack the authentication of unspecified victims by tricking authenticated users into submitting malicious requests to the WebEx platform.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) for all state-changing operations in WebEx Training Center, and validate the Origin/Referer headers on server-side requests to prevent unauthorized cross-origin requests.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm WebEx Training Center deployment
    Identify if Cisco WebEx Training Center is hosted in your environment by accessing the WebEx URL and verifying the Training Center component is active. Check server response headers and application URLs for '/training/' paths or 'trainingcenter' in the hostname.
    Affected if WebEx Training Center is deployed and accessible without additional CSRF protections.
  2. Inspect HTML forms for anti-CSRF tokens
    Log into WebEx Training Center as a valid user and use browser developer tools to view the source of state-changing forms (registration, user management, meeting creation). Look for hidden input fields containing random tokens, or check form action URLs for token parameters.
    Affected if Forms lack hidden CSRF token fields and rely solely on session cookies for authentication.
  3. Verify session cookie SameSite attribute
    Open browser developer tools, go to the Application/Storage tab, and examine the session cookies for the WebEx domain. Check if the SameSite attribute is set to 'Strict' or 'Lax', or is absent (which defaults to None in older browsers).
    Affected if Session cookies have no SameSite attribute set, allowing cross-origin requests to proceed.
  4. Check for Origin/Referer header validation
    Submit a cross-origin request to WebEx Training Center (using a tool like curl or Burp) with a mismatched Origin header. Observe if the request is rejected or accepted. Alternatively, review server-side logs for any header validation logic.
    Affected if Requests with mismatched Origin/Referer headers are processed without rejection, indicating lack of server-side CSRF protection.
  5. Test state-changing operations via cross-origin request
    Create a proof-of-concept HTML page hosted on a different domain that automatically submits a form to the WebEx Training Center endpoint (such as changing user settings or joining a meeting). If the action succeeds without requiring re-authentication, CSRF protection is absent.
    Affected if Cross-origin form submissions execute successfully without token validation or re-authentication.

If WebEx Training Center is deployed and forms lack anti-CSRF tokens, session cookies lack SameSite attributes, and the server does not validate Origin/Referer headers, the environment is vulnerable to CVE-2013-6710.
