Security readout for executives and security teams
Plain-English summary
This issue lets a low-privileged Jenkins user list credential IDs stored in Jenkins when the Synopsys Jenkins Coverity Plugin is installed. It does not disclose credential secret values, but credential names can reveal sensitive operational context and help further attacks.
Executive priority
Treat this as a moderate Jenkins hardening item. It does not expose passwords directly, but it can reveal credential inventory details that make follow-on attacks easier. Prioritize internet-accessible or broadly shared Jenkins environments.
Technical view
CVE-2023-23850 is a missing permission check in Synopsys Jenkins Coverity Plugin 3.0.2 and earlier. An attacker with Jenkins Overall/Read permission can enumerate stored Jenkins credential IDs. CVSS 3.1 is 4.3 with network access, low complexity, low privileges, and confidentiality-only impact.
Likely exposure
Exposure is limited to Jenkins environments running Synopsys Jenkins Coverity Plugin 3.0.2 or earlier where untrusted or broad user groups have Overall/Read permission.
Exploitation context
The supplied sources do not report active exploitation, and the CVE is not listed as KEV. The risk is mainly information disclosure that may support later attacks, especially in Jenkins environments with many authenticated users.
Researcher notes
The public bundle identifies CWE-862 and CWE-276, indicating missing authorization and permission-control weakness. Evidence supports credential ID enumeration only, not secret-value disclosure, code execution, integrity impact, availability impact, or active exploitation.
Mitigation direction
- Inventory Jenkins instances for Synopsys Jenkins Coverity Plugin 3.0.2 or earlier.
- Check Jenkins and Synopsys advisories for current fixed-version guidance.
- Restrict Overall/Read permission to trusted users where operationally possible.
- Remove or disable the plugin if Coverity integration is not required.
- Review credential naming practices to avoid exposing sensitive system context.
Validation and detection
- Confirm whether the Coverity plugin is installed on each Jenkins controller.
- Record installed plugin versions and identify versions 3.0.2 or earlier.
- Review Jenkins authorization strategy for users with Overall/Read permission.
- Confirm remediation guidance from Jenkins or Synopsys before closing the finding.
- Document remaining business need for the plugin if it cannot be removed.
