Security readout for executives and security teams
This flaw lets an authenticated user place JavaScript into the IBM Rational Team Concert web interface. If another user views the affected content, the script can run inside that trusted session and may expose credentials or alter page behavior. The business risk is moderate, concentrated where RTC is still used for source control or engineering workflows. Exposure is limited to organizations running IBM Rational Team Concert versions 5.0, 5.0.1, 5.0.2, or 6.0 through 6.0.6. Risk depends on whether the web UI is reachable by untrusted or broadly provisioned users. Treat this as a focused remediation item, not an emergency. Prioritize if RTC is internet-facing, used by contractors, or contains sensitive engineering work. Legacy RTC instances should be upgraded or isolated because trusted-session credential exposure can affect development operations. Mitigation focus: Identify all Rational Team Concert deployments and confirm exact versions.; Review IBM advisory 10875364 for official fixes or update guidance.; Apply IBM's official fix or supported upgrade path where applicable..
