Who should care

IBM Jazz Team Server and IBM Rational Collaborative Lifecycle Management administrators, especially teams operating the affected 4.0.0-6.0.3 release line, should review this issue. Security teams should also care because even low-impact disclosure can help attackers map internal deployments and plan follow-on activity.

Technical summary

NVD lists CVSS 3.0 vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N and CWE-200, indicating a network-reachable information disclosure condition that requires low-privileged authenticated access. The record states that an unspecified vulnerability in IBM Jazz Team Server may disclose deployment information to an authenticated user. The affected CPEs cover IBM Rational Collaborative Lifecycle Management versions 4.0.0 through 6.0.3. No integrity or availability impact is described in the supplied corpus.

Defensive priority

Medium. The issue does not indicate code execution or service disruption, but it can reveal deployment details that may aid reconnaissance and later attacks. Prioritize remediation if the product is internet-facing or if authenticated users are not fully trusted.

Recommended defensive actions

  • Check whether any IBM Jazz Team Server or IBM Rational Collaborative Lifecycle Management instances are running versions 4.0.0 through 6.0.3.
  • Review IBM support advisory swg21997104 for vendor remediation guidance and apply the recommended patch or update path.
  • Restrict authenticated access to trusted users only and review privilege assignments for accounts that do not need access to the affected service.
  • Monitor logs for unusual authenticated requests that could indicate reconnaissance or attempts to enumerate deployment details.
  • If immediate patching is not possible, limit exposure of the service to internal networks and segment administrative interfaces.
