IBM Jazz Foundation (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: 214619.

Security readout for executives and security teams

Plain-English summary

IBM Jazz Team Server has a medium-severity web UI flaw that can let an authenticated user place JavaScript into trusted pages. If another user interacts with that content, the script could alter page behavior or expose credentials within that user’s session.

Executive priority

Treat this as a targeted remediation item, not a crisis. Prioritize systems used by developers, administrators, or sensitive project teams because trusted-session credential exposure could create follow-on business risk.

Technical view

CVE-2021-39059 is a cross-site scripting issue in IBM Jazz Foundation / Jazz Team Server versions 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2. The CVSS 3.0 score is 5.4, with network attack vector, low privileges required, user interaction required, changed scope, and low confidentiality/integrity impact.

Likely exposure

Exposure is most likely where affected Jazz Team Server versions remain deployed with accessible web UI functions. The vulnerability requires an authenticated user and user interaction, so risk depends on who can create or influence UI content and who later views it.

Exploitation context

The source bundle does not state active exploitation, and KEV is false. The CVSS vector includes low attack complexity and high exploit maturity, but no exploit procedure, incident evidence, or public exploitation claim is provided here.

Researcher notes

Evidence identifies XSS and affected versions, but does not include a CWE, concrete vulnerable endpoint, exploit steps, or fixed version details in the provided bundle. Validation should focus on version exposure, IBM advisory status, and authenticated content-entry surfaces.

Mitigation direction

  • Check IBM advisory 6584347 for the official fix path for your Jazz Team Server version.
  • Upgrade or patch affected Jazz Team Server deployments according to IBM guidance.
  • Restrict Jazz web UI access to trusted users and networks where operationally possible.
  • Review credentials for users who interacted with untrusted Jazz content before remediation.

Validation and detection

  • Inventory Jazz Team Server versions and flag 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2.
  • Confirm remediation status against IBM advisory 6584347, not version assumptions alone.
  • Review application logs for suspicious content changes or unusual authenticated user activity.
  • Verify user roles that can create or edit web UI content in Jazz.
