CVE-2018-1407: IBM Rational Team Concert 5.0 through 5.0.2 and 6.0 through 6.0.5 are vulnerable to cross-site scripting.

IBM Rational Team Concert 5.0 through 5.0.2 and 6.0 through 6.0.5 are 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: 138445.

Security readout for executives and security teams

Plain-English summary

CVE-2018-1407 is a cross-site scripting issue in IBM Rational Team Concert. An authenticated user could place JavaScript into the Web UI, potentially changing what another trusted user sees or exposing credentials within that session.

Executive priority

Handle as a moderate priority for legacy IBM development environments. It is not KEV-listed, but it can affect trusted user sessions and credentials, so exposed or business-critical RTC instances should be remediated promptly.

Technical view

Affected IBM Rational Team Concert versions are 5.0 through 5.0.2 and 6.0 through 6.0.5. The CVSS 3.0 score is 5.4 with network attack vector, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to organizations running the listed IBM Rational Team Concert versions with the Web UI reachable by authenticated users. Internet exposure increases risk, but the source bundle does not state deployment prevalence.

Exploitation context

CISA KEV is false and the supplied sources do not cite active exploitation. The CVSS temporal vector includes E:H, indicating IBM assessed exploit maturity as high, but this does not prove exploitation in the wild.

Researcher notes

The bundle does not identify the vulnerable parameter, proof of concept, or exact fixed version. Analysis should stay version-focused and advisory-driven. Validate exposure through inventory and vendor remediation status, not exploit reproduction.

Mitigation direction

  • Review the IBM advisory for the official fix or supported upgrade path.
  • Upgrade affected Rational Team Concert versions according to IBM guidance.
  • Restrict Web UI access to trusted networks and required users.
  • Monitor for suspicious script content or unexpected UI changes.
  • Treat credential exposure risk as session-scoped and review affected accounts if abuse is suspected.

Validation and detection

  • Inventory Rational Team Concert servers and confirm installed versions.
  • Check whether Web UI access is exposed beyond intended user groups.
  • Verify IBM advisory remediation has been applied.
  • Review application logs for suspicious authenticated content changes.
  • Confirm no users remain on affected 5.0.x or 6.0.x versions listed.
