CVE-2021-38871: IBM Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2 is vulnerable to cross-site scripting.

IBM Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 208345.

Security readout for executives and security teams

Plain-English summary

IBM Jazz Team Server versions 6.0.6 through 7.0.2 can let a user embed JavaScript in the web UI. If another user interacts with the affected page, the script could alter trusted-session behavior and expose credentials or session-sensitive data.

Executive priority

Treat as a medium-priority application security fix. It is not listed as actively exploited in the supplied evidence, but it can affect credentials inside a trusted collaboration system and should be remediated in normal patch cycles, faster for exposed deployments.

Technical view

This is a network-reachable cross-site scripting issue with low attack complexity, low privileges required, and user interaction required. The supplied CVSS vector is 5.4 with changed scope and low confidentiality and integrity impact. IBM X-Force tracks it as ID 208345.

Likely exposure

Exposure is limited to IBM Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2. Risk is higher where the web UI is reachable by many authenticated users, contractors, or federated identities.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVSS vector includes E:H, but that is not proof of active exploitation. Practical abuse depends on placing script content where another trusted user will view or trigger it.

Researcher notes

Do not broaden scope beyond IBM Jazz Team Server versions listed in the bundle. Evidence supports XSS with PR:L and UI:R. The advisory reference should be used for exact fixed versions because the supplied bundle does not name them.

Mitigation direction

  • Identify all IBM Jazz Team Server instances and versions.
  • Review IBM advisory node 6597503 for official fixes or upgrade guidance.
  • Prioritize remediation for internet-facing or broadly accessible deployments.
  • Restrict access to affected web UI until remediation is complete.
  • Review XSS-relevant controls such as input handling and session protections.

Validation and detection

  • Confirm deployed Jazz Team Server versions against the affected version list.
  • Check whether IBM advisory fixes have been applied.
  • Review logs for unusual script-bearing content or UI manipulation reports.
  • Verify access controls limit untrusted low-privilege contributors.
  • Run regression checks for stored or reflected XSS after remediation.
