IBM Jazz for Service Management and IBM Tivoli Netcool/OMNIbus_GUI 8.1.0 is vulnerable to stored 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: 204265.

Security readout for executives and security teams

Plain-English summary

This issue lets a low-privileged user store JavaScript in the IBM web interface. When trusted users use the affected UI, that script can change page behavior and may expose credentials within their session. It is moderate business risk for environments still running the affected IBM monitoring stack.

Executive priority

Treat this as a targeted remediation item, not an internet-wide emergency. Prioritize if the affected IBM console is still in production, supports critical monitoring operations, or is used by privileged administrators.

Technical view

CVE-2021-29807 is stored cross-site scripting in IBM Jazz for Service Management and IBM Tivoli Netcool/OMNIbus_GUI 8.1.0. The CVSS 3.0 score is 6.4 with network attack vector, low complexity, low privileges required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is most likely where IBM Tivoli Netcool/OMNIbus GUI 8.1.0 or the associated Jazz for Service Management Web UI remains deployed, especially with multiple users able to create or modify Web UI content.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The risk is still practical because stored XSS can persist inside an operational console and affect trusted sessions after content is saved.

Researcher notes

The source bundle identifies stored XSS and IBM X-Force ID 204265 but does not include detailed vulnerable fields, patch identifiers, or exploitation evidence. Avoid assuming broader IBM product impact beyond the named Jazz for Service Management and Netcool/OMNIbus_GUI 8.1.0 scope.

Mitigation direction

  • Review IBM advisory 6490747 and X-Force ID 204265 for the official fix level.
  • Patch or upgrade affected IBM Tivoli Netcool/OMNIbus GUI 8.1.0 deployments per IBM guidance.
  • Limit Web UI content-editing privileges until remediation is complete.
  • Monitor the application for unexpected saved markup or script-like content.
  • Review session and credential exposure assumptions for users of the affected console.

Validation and detection

  • Inventory IBM Jazz for Service Management and Netcool/OMNIbus GUI deployments.
  • Confirm whether any deployment is version 8.1.0 and includes the affected Web UI.
  • Check whether IBM's official fix or upgrade has been applied.
  • Review user-editable Web UI content for unexpected script-bearing markup.
  • Confirm privileged console users changed credentials if exposure is suspected.
