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
IBM Jazz Team Server products is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

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.

How this class of weakness works · CWE-918

The server can be induced to make requests to a URL an attacker controls, turning it into a proxy into internal networks and cloud metadata services. It's especially dangerous behind a trusted network boundary. The fix is strict allow-listing of destinations and blocking access to internal address ranges.

Recommended fix High confidence
  1. 1. Navigate to the IBM support page at https://www.ibm.com/support/pages/node/6508583 to obtain the appropriate patch for your specific IBM Jazz product and version.
  2. 2. Identify the exact fix package corresponding to your affected product (Engineering Lifecycle Optimization, Engineering Requirements Quality Assistant, Engineering Workflow Management, Rational Doors Next Generation, Rational Engineering Lifecycle Manager, Rational Rhapsody Design Manager, or Rational Team Concert).
  3. 3. Download the recommended patch or interim fix from the IBM support page.
  4. 4. Review the IBM installation instructions for applying the patch to your specific product.
  5. 5. Apply the patch to all affected Jazz Team Server instances in your environment.
  6. 6. After applying the patch, verify that the SSRF vulnerability is resolved by testing that the affected endpoints no longer allow unauthorized server-side requests.
  7. 7. Confirm that authenticated users can no longer exploit the SSRF vector to perform network enumeration or other unauthorized requests.
