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
Open redirect vulnerability in Cisco WebEx Training Center allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors, aka Bug ID CSCul57140.

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

Open redirect vulnerability in Cisco WebEx Training Center allows remote attackers to craft malicious URLs that redirect users to arbitrary external websites, facilitating phishing attacks. The vulnerability stems from insufficient validation of redirect destination parameters in the application.

MitigationImplement strict URL validation using an allowlist approach for all redirect parameters, ensuring only trusted domains are permitted. Additionally, implement anti-phishing protections such as prominent warnings when redirecting to external domains.

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 Cisco WebEx Training Center is deployed
    Identify if your organization uses Cisco WebEx Training Center. Check installed applications, web servers, or consult with IT administrators for any Cisco WebEx-related software or services.
    Affected if The product is in use and has a web-facing component
  2. Identify the WebEx Training Center web URL
    Locate the URL used to access Cisco WebEx Training Center. This is typically accessed via a specific web URL (such as trainingcenter.webex.com or a custom domain).
    Affected if You have a working URL to access the WebEx Training Center interface
  3. Inspect URLs for redirect parameters
    Examine the URL structure when navigating through the application. Look for parameters that control navigation, such as those containing 'redirect', 'url', 'dest', 'target', or similar terms that specify where a user should be sent.
    Affected if The application URL contains redirect-related parameters in the query string
  4. Test for unvalidated redirect behavior
    Modify any identified redirect parameter to point to an external domain (for example, change the parameter value to example.com). Submit the modified URL and observe if the application redirects to the untrusted domain without validation warnings.
    Affected if The application redirects to the arbitrary external domain specified in the modified parameter without proper validation or warning

Your environment is affected if Cisco WebEx Training Center is deployed and the application permits redirection to arbitrary external domains via URL parameters.
