Security readout for executives and security teams
Plain-English summary
This issue affects Jenkins environments using the Synopsys Coverity plugin. An attacker who already has some Jenkins access and can trick a user into an action may cause Jenkins to send stored credentials to an attacker-controlled server. The business risk is targeted credential exposure, not direct system takeover.
Executive priority
Treat as a low-priority but real credential-protection issue. Address during regular Jenkins maintenance unless the plugin is internet-exposed, broadly accessible, or tied to high-value credentials, in which case prioritize inventory and credential review.
Technical view
CVE-2023-23847 is a CWE-352 CSRF flaw in Synopsys Jenkins Coverity Plugin 3.0.2 and earlier. The published description says attackers can connect to an attacker-specified HTTP server using attacker-specified credential IDs obtained separately, allowing capture of Jenkins-stored credentials.
Likely exposure
Exposure is limited to Jenkins instances with Synopsys Jenkins Coverity Plugin 3.0.2 or earlier installed. Risk increases where low-privileged users can access Jenkins and stored credentials are available to Coverity configuration or jobs.
Exploitation context
The source bundle reports no CISA KEV listing and provides no evidence of active exploitation. The CVSS vector requires network access, low privileges, and user interaction, with low confidentiality impact and no integrity or availability impact.
Researcher notes
The public data is specific about the vulnerable plugin versions and impact path, but does not include exploitation evidence in the provided bundle. Avoid assuming broader Jenkins impact; this is scoped to the Synopsys Jenkins Coverity Plugin.
Mitigation direction
- Inventory Jenkins instances for Synopsys Coverity Plugin 3.0.2 or earlier.
- Check Jenkins and Synopsys advisories for the supported fixed version or mitigation.
- Disable or remove the plugin where Coverity integration is not required.
- Restrict Jenkins access and plugin configuration permissions to trusted administrators.
- Review and rotate potentially exposed Jenkins credentials if suspicious activity is found.
Validation and detection
- Confirm whether the Coverity plugin is installed on each Jenkins controller.
- Record the installed plugin version and compare it with advisory guidance.
- Review Jenkins audit logs for unexpected Coverity configuration or connection activity.
- Check outbound network logs for Jenkins connections to untrusted HTTP servers.
- Identify credentials referenced by Coverity jobs or plugin configuration.

Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
