CVE-2025-24403 is identified as a medium-severity vulnerability affecting the Jenkins Azure Service Fabric Plugin, specifically version 1.6 and earlier. This vulnerability allows attackers with Overall/Read permission to enumerate credentials IDs of Azure credentials stored within Jenkins. The implications of this weakness enable unauthorized access to potentially sensitive information, which could lead to further exploits.
The CVSS score for this vulnerability is 4.3, indicating its medium severity. The score reflects a low attack complexity with network-based attack vectors, requiring only low privileges, and does not necessitate user interaction. Therefore, organizations must understand the risk to their systems and prioritize remediation.
As this vulnerability is actively being analyzed and does not currently have a known exploit, organizations should not delay in addressing it. The publication date was January 22, 2025, and with the evolving threat landscape, immediate action is warranted.
Organizations should prioritize patching immediately to prevent unauthorized access to Azure credentials. Failure to do so could expose sensitive data and create avenues for attackers to compromise systems.
Vulnerability Details
The official description states that a missing permission check in Jenkins Azure Service Fabric Plugin versions prior to 1.6 allows attackers to enumerate credentials IDs, posing a significant risk to organizations using this plugin.
The vulnerability is classified under CWE-862, relating to insufficient access control. Given the medium CVSS score of 4.3, the vulnerability is characterized by a network attack vector with low complexity, requiring low privileges and no user interaction.
Affected systems include all versions of the Jenkins Azure Service Fabric plugin prior to version 1.6, which is critical for organizations to address promptly.
Technical Analysis
The root cause of this vulnerability lies in the absence of proper permission checks within the Jenkins Azure Service Fabric Plugin. Attackers leveraging this vulnerability can exploit the permission misconfiguration to gain visibility into sensitive credentials stored in Jenkins.
The attack vector is characterized as network-based, allowing remote attackers to exploit the weakness without needing to be physically present. The attack complexity is low, making it easier for potential attackers to execute an exploit. Privileges required are also low, which raises concerns regarding the ability of unauthorized users to gain access to sensitive information without significant barriers.
In terms of impact, the confidentiality of the Azure credentials is at risk, while integrity and availability are not directly impacted. Organizations must monitor for any signs of unauthorized access or credential enumeration attempts.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-24403 includes potential exposure of sensitive Azure credentials, which could lead to unauthorized access to cloud resources. This could enable attackers to perform malicious actions, including data exfiltration or further attacks within the organization.
Organizations leveraging Jenkins for their Azure services should consider the blast radius of this vulnerability, as it could affect all users with Overall/Read permissions, thereby amplifying the risk significantly.
Given the CVSS score of 4.3 and the fact that it is not currently included in the KEV catalog, organizations should still address this vulnerability in their patching cycles. The urgency for remediation is classified as medium, and organizations should schedule remediation to ensure their systems are secure.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to the vendor patch are affected by this vulnerability, specifically the Jenkins Azure Service Fabric Plugin version 1.6 and earlier.
Mitigation & Remediation
Organizations should prioritize patching the Jenkins Azure Service Fabric Plugin to version 1.7 or later to mitigate this vulnerability. In instances where immediate patching is not feasible, organizations should consider implementing access controls to restrict Overall/Read permissions as a temporary workaround.
Additionally, organizations should review their configurations and harden their network controls to prevent unauthorized access attempts. Continuous monitoring for unusual activity regarding credential enumeration is also recommended.
For more information on effective penetration testing strategies to identify vulnerabilities, organizations can refer to penetration testing services.
Detection Guidance
Organizations should monitor logs for any indicators of unauthorized access attempts, particularly related to the enumeration of Azure credentials. Behavioral anomalies in user activity, especially those with Overall/Read permissions, should be closely observed.
Implementing network signatures that can detect abnormal requests to the Jenkins server can also help in identifying potential exploitation attempts.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-24403 underscores the need for rigorous access control measures within CI/CD pipelines, particularly those integrated with cloud services. This vulnerability exemplifies the patterns observed in many security breaches, where insufficient permission checks lead to data exposure.
Security teams should take this incident as a learning opportunity to reinforce their security posture by conducting regular assessments and updating their configurations. The importance of proactive security measures cannot be overstated.
Organizations seeking to enhance their security framework may find value in reviewing best practices in vulnerability management and penetration testing methodology to prevent similar vulnerabilities.
In summary, CVE-2025-24403 presents a clear example of how oversight in permission checks can lead to significant security risks. By prioritizing remediation, organizations can safeguard their systems from potential exploitation.
