Security readout for executives and security teams
Plain-English summary
CVE-2021-29813 is a stored cross-site scripting issue in IBM Jazz for Service Management 1.1.3.10, with IBM also naming Tivoli Netcool/OMNIbus_GUI in the description. An authenticated user could store JavaScript in the Web UI, changing page behavior and potentially exposing credentials inside a trusted session.
Executive priority
Treat as a moderate operational security item. It is not described as actively exploited, but affected monitoring or service-management interfaces may hold trusted sessions and sensitive credentials. Prioritize if exposed beyond a tightly controlled admin group.
Technical view
The vulnerability is stored XSS with CVSS 3.0 score 6.4. The vector indicates network reachability, low privileges required, low attack complexity, changed scope, and low confidentiality and integrity impact. The source bundle does not identify a CWE or provide exploit details. IBM X-Force tracks it as ID 204331.
Likely exposure
Exposure is most likely where IBM Jazz for Service Management 1.1.3.10 or the IBM Tivoli Netcool/OMNIbus GUI Web UI is deployed and accessible to authenticated users. Internet exposure, broad internal access, or shared operational accounts would increase business risk.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. The exploitability signal is authenticated stored XSS: a low-privileged user may persist malicious script in the UI, affecting later trusted sessions without needing victim interaction per the CVSS vector.
Researcher notes
Key gaps: the prompt does not include exact fixed versions, affected CPEs, or proof of exploitation. Do not broaden affected products beyond IBM’s named products. Focus validation on installed version, authenticated Web UI reachability, and whether vendor remediation has been applied.
Mitigation direction
- Check IBM advisory node 6491543 for the official remediation.
- Apply IBM-provided fixes or upgrades for affected deployments.
- Restrict Web UI access to trusted users and networks.
- Review user privileges for accounts that can submit stored UI content.
- Monitor for suspicious UI content changes and credential anomalies.
Validation and detection
- Inventory Jazz for Service Management and Netcool/OMNIbus GUI deployments.
- Confirm whether any deployment runs Jazz for Service Management 1.1.3.10.
- Compare installed levels with IBM advisory guidance.
- Review authentication and Web UI logs for unusual stored-content activity.
- Validate remediation in a controlled environment without using live credentials.
