CVE-2025-24397 is a medium-severity vulnerability discovered in the Jenkins GitLab Plugin, specifically version 1.9.6 and earlier. This vulnerability allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate credential IDs of GitLab API token and Secret text credentials stored in Jenkins. The potential exposure of sensitive credential information poses a significant risk to organizations using this plugin.
The vulnerability has a CVSS score of 4.3, indicating its medium severity. Organizations should prioritize addressing this issue, especially since it can be exploited over a network with low complexity and minimal privileges required. Active exploitation has not been reported, but the potential for credential enumeration presents a concerning threat.
Given its implications, organizations should assess their use of the Jenkins GitLab Plugin and implement necessary patches or mitigations promptly. The urgency to patch is underscored by the risk to sensitive data and the potential for unauthorized access to systems.
As of now, there are no known exploits in the wild. However, the nature of the vulnerability could be appealing to attackers, making it essential for organizations to monitor their systems for any unusual activity related to Jenkins.
Organizations should prioritize patching immediately. Regular updates and security assessments can help mitigate such vulnerabilities and reduce the risk of exploitation.
Vulnerability Details
The vulnerability is characterized by an incorrect permission check in the Jenkins GitLab Plugin versions 1.9.6 and earlier. This flaw is categorized under CWE-863, indicating an issue with permissions. The attack vector is network-based, requiring low complexity and only low privileges for exploitation.
The CVSS score of 4.3 reflects the medium severity of the vulnerability. Its publication date was January 22, 2025, with the last modification on October 3, 2025.
Technical Analysis
The root cause of this vulnerability lies in the inadequate permission checks implemented within the Jenkins GitLab Plugin. Attackers can exploit this flaw to enumerate credential IDs, which could lead to further attacks or unauthorized access to systems. The attack complexity is low, and no user interaction is required for exploitation.
The implications of this vulnerability include a low confidentiality impact since attackers may gain access to sensitive credential IDs but not the actual credentials themselves. There is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
The real-world risk of CVE-2025-24397 relates to the potential exposure of sensitive GitLab API tokens and Secret text credentials stored in Jenkins. If exploited, attackers could leverage this information to gain unauthorized access to systems or data, increasing the blast radius significantly.
Organizations using Jenkins should be particularly vigilant, given that the exploitability of this vulnerability is medium, and it can be exploited remotely. The overall risk to organizations includes unauthorized data access and potential data breaches.
The urgency for remediation is high, and organizations should address this vulnerability in their priority patch cycle. Failure to do so may leave systems exposed to potential attacks.
