IBM Quality Manager (RQM) 6.02, 6.06, and 6.0.6.1 could allow an authenticated user to create keywords through the REST API and have them appear as if they were created by another user. IBM X-Force ID: 168295.

Security readout for executives and security teams

Plain-English summary

CVE-2019-4603 affects IBM Rational Quality Manager versions 6.0.2, 6.0.6, and 6.0.6.1. An authenticated user could create keywords through the REST API so they appear attributed to another user, weakening audit integrity rather than causing data theft or outage.

Executive priority

Treat as a moderate-priority integrity issue. It is unlikely to drive emergency response by itself, but it can undermine accountability in quality-management workflows, especially where RQM records support regulated releases, audit evidence, or change-control decisions.

Technical view

The source describes a spoofing issue in IBM RQM’s REST API keyword creation path. CVSS 3.0 is 4.3: network-accessible, low attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality or availability impact, and low integrity impact.

Likely exposure

Exposure is limited to organizations running IBM Rational Quality Manager 6.0.2, 6.0.6, or 6.0.6.1 with authenticated users able to reach the REST API. The bundle does not identify other affected products or versions.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVSS vector marks exploit maturity as unproven. Abuse would require authenticated access and would mainly affect attribution and trust in RQM keyword records.

Researcher notes

Evidence is concise: affected versions, REST API keyword spoofing behavior, IBM X-Force ID 168295, and CVSS vector are provided. No CWE, exploit details, or exact fixed release are included in the bundle, so remediation should be verified against IBM guidance.

Mitigation direction

  • Identify any IBM RQM 6.0.2, 6.0.6, or 6.0.6.1 deployments.
  • Review IBM’s advisory for the official fix or upgrade path.
  • Restrict REST API access to required authenticated users only.
  • Review RQM keyword audit records for suspicious attribution anomalies.

Validation and detection

  • Inventory RQM versions and confirm whether listed vulnerable versions are present.
  • Confirm REST API exposure is limited to trusted networks or users.
  • Check whether IBM’s official remediation has been applied.
  • Review logs or records for keyword creation attributed unexpectedly.
