A cross-site request forgery (CSRF) vulnerability in Jenkins Azure Service Fabric Plugin 1.6 and earlier allows attackers to connect to a Service Fabric URL using attacker-specified credentials IDs obtained through another method. This vulnerability has been classified with a CVSS score of 4.3, indicating a medium severity level.
Risk to organizations includes potential unauthorized access to sensitive components of the Service Fabric. Attackers may leverage this vulnerability to gain control over systems, impacting confidentiality and potentially leading to further exploits.
Organizations should prioritize patching immediately. The vulnerability was disclosed on January 22, 2025, and continues to pose a risk given the lack of available exploits in the public domain.
As of the latest information, this vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it has not been actively exploited in the wild but should not be overlooked in security assessments.
Vulnerability Details
The official description states that this vulnerability allows attackers to exploit CSRF weaknesses to connect to Service Fabric URLs using credentials obtained through means other than direct user input. The affected product is the Jenkins Azure Service Fabric Plugin, specifically versions 1.6 and earlier.
The CVSS score of 4.3 indicates a medium severity level, primarily due to the attack vector being network-based with low complexity and requiring low privileges, while the confidentiality impact is rated as low.
The vulnerability is classified under CWE-352, which refers to CSRF vulnerabilities, highlighting the nature of the flaw.
Technical Analysis
The root cause of this vulnerability stems from insufficient protection against CSRF attacks in the Jenkins Azure Service Fabric Plugin. Attackers can exploit the lack of proper CSRF tokens to connect to Service Fabric URLs by manipulating user sessions.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability without needing physical access to the target system. The low attack complexity means that attackers can easily execute the CSRF attack without requiring additional conditions or configurations.
The privileges required are low, meaning that an attacker does not need elevated permissions to carry out the attack. User interaction is not required, which increases the risk as it can be executed without user consent or awareness.
The confidentiality impact is rated as low, indicating that while sensitive information may be accessed, it does not necessarily lead to a complete exposure of all data. Integrity and availability impacts are rated as none, suggesting that the attack does not modify or disrupt services.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is significant, especially for organizations using Jenkins in environments where Service Fabric is deployed. The potential for unauthorized access to service endpoints can lead to further vulnerabilities or breaches.
The urgency for addressing this vulnerability is moderate, given the CVSS score and the fact that it is not currently being actively exploited. Organizations should schedule remediation and consider the impact on their operational security.
With the potential blast radius being considerable, organizations must evaluate their deployment of the Jenkins Azure Service Fabric Plugin and assess any existing security controls that may mitigate the risk posed by this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects the Jenkins Azure Service Fabric Plugin version 1.6 and earlier. All versions prior to the vendor patch are vulnerable.
Mitigation & Remediation
Organizations should update to the latest version of the Jenkins Azure Service Fabric Plugin to mitigate this vulnerability. If immediate patching is not feasible, implement CSRF tokens to secure endpoints.
Consider applying configuration hardening to restrict access to sensitive service endpoints and utilize network controls to limit exposure.
Monitoring for unusual access patterns and failed authentication attempts can provide early indicators of potential exploitation.
Penetration testing can also help identify weaknesses and validate remediation efforts.
Detection Guidance
Organizations should monitor logs for unusual access patterns, especially around service endpoints related to the Azure Service Fabric. Behavioral anomalies may indicate attempts to exploit the vulnerability.
Network signatures should be established to detect potential CSRF attack patterns, and any changes to system configurations should be closely monitored.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability is that it highlights ongoing issues with CSRF protections in web applications. Security teams must remain vigilant in implementing security best practices to mitigate such risks.
The vulnerability represents a trend of inadequate security measures in plugins and extensions, emphasizing the need for regular security reviews and updates.
Vulnerability management programs should incorporate assessments of third-party plugins to fortify defenses against such vulnerabilities.
In conclusion, organizations must be proactive in their security posture by adopting comprehensive security strategies that include regular updates, monitoring, and vulnerability assessments to counteract the evolving threat landscape.
