Security readout for executives and security teams
Plain-English summary
This flaw lets a low-privileged Jenkins user misuse the Synopsys Coverity plugin to make Jenkins send stored credentials to an attacker-controlled HTTP server, if they already know a valid credentials ID. The direct CVSS rating is medium, but leaked CI credentials can create wider business risk.
Executive priority
Treat this as a near-term Jenkins hardening issue, especially where Jenkins stores production, deployment, SCM, or cloud credentials. It is not listed as actively exploited, but credential exposure from CI systems can enable follow-on compromise beyond Jenkins.
Technical view
Synopsys Jenkins Coverity Plugin 3.0.2 and earlier lacked required permission checks. An attacker with Overall/Read permission could trigger a connection to an attacker-specified HTTP server using attacker-specified Jenkins credentials IDs obtained separately, exposing stored credentials. CVSS 3.1 is 4.3 with low confidentiality impact.
Likely exposure
Exposure is limited to Jenkins environments running Synopsys Jenkins Coverity Plugin 3.0.2 or earlier. The attacker needs Jenkins Overall/Read access and a valid credentials ID learned through another path. Internet exposure of Jenkins increases practical risk but is not required by the CVE description.
Exploitation context
The source bundle does not cite active exploitation, and the CVE is not marked CISA KEV. Exploitation is authenticated and depends on access to Jenkins plus knowledge of a credentials ID. The main concern is credential capture, not direct code execution.
Researcher notes
Evidence supports missing authorization checks and improper permission handling, mapped to CWE-862 and CWE-276. The CVE scope is unchanged with confidentiality impact only. The bundle does not include exploit proof, active exploitation evidence, or detailed fixed-version text beyond identifying 3.0.2 and earlier as affected.
Mitigation direction
- Identify Jenkins instances using the Synopsys Coverity plugin.
- Upgrade from plugin version 3.0.2 or earlier per Jenkins or Synopsys guidance.
- Restrict Jenkins Overall/Read access to trusted users only.
- Review and rotate credentials that may be exposed through Jenkins.
- Limit Jenkins outbound network access where operationally feasible.
Validation and detection
- Check installed Synopsys Coverity plugin versions across Jenkins controllers.
- Review Jenkins user and group assignments for Overall/Read permission.
- Audit Jenkins credentials referenced by Coverity jobs or configurations.
- Review logs for unexpected Coverity plugin connections to external HTTP endpoints.
- Confirm remediation against Jenkins and Synopsys advisory guidance.
