Summary
by MITRE • 02/15/2022
A cross-site request forgery (CSRF) vulnerability in Jenkins Snow Commander Plugin 2.0 and earlier allows attackers to connect to an attacker-specified webserver using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

This cross-site request forgery vulnerability exists within the Jenkins Snow Commander Plugin version 2.0 and earlier, representing a critical security flaw that enables unauthorized attackers to exploit the plugin's functionality for credential theft. The vulnerability stems from insufficient validation of request origins and lack of proper anti-CSRF token implementation within the plugin's web interface. Attackers can craft malicious requests that appear to originate from legitimate Jenkins users, thereby exploiting the trust relationship between the web application and its authenticated users. The flaw specifically targets the plugin's ability to connect to external servers using stored credential identifiers, creating an attack vector where credentials can be exfiltrated through crafted requests.
The technical implementation of this vulnerability involves the absence of proper CSRF protection mechanisms that should validate the authenticity of requests originating from the Jenkins web interface. When users interact with the Snow Commander Plugin, the application fails to verify that requests are genuinely initiated by the authenticated user rather than by malicious actors who have constructed deceptive web requests. This weakness allows attackers to leverage stolen session tokens or other authentication credentials to execute unauthorized operations against the Jenkins instance. The vulnerability is particularly dangerous because it operates at the application layer and can be exploited without requiring elevated privileges or direct system access, making it an attractive target for attackers seeking to escalate their access within Jenkins environments.
The operational impact of this vulnerability extends beyond simple credential theft, as compromised credentials can provide attackers with persistent access to external systems that Jenkins connects to through the Snow Commander Plugin. Attackers can utilize the stolen credentials to establish unauthorized connections to Snowflake or other database systems, potentially leading to data exfiltration, system compromise, or further lateral movement within the network infrastructure. The attack surface is significantly expanded when considering that Jenkins typically serves as a central automation hub in CI/CD pipelines, making compromised credentials particularly valuable for attackers seeking to manipulate build processes, access source code repositories, or gain access to production environments. This vulnerability directly aligns with CWE-352, which defines Cross-Site Request Forgery as a weakness where a web application fails to validate that requests originate from legitimate users.
Mitigation strategies for this vulnerability should include immediate plugin updates to versions that implement proper CSRF protection mechanisms and anti-forgery tokens. Organizations should also consider implementing additional security controls such as network segmentation to limit access to Jenkins instances, regular credential rotation policies, and monitoring for unusual connection patterns to external systems. The implementation of web application firewalls and enhanced session management controls can provide additional layers of protection against similar attacks. Security teams should also conduct thorough audits of all Jenkins plugins to identify other potentially vulnerable components that may lack proper CSRF protection mechanisms. This vulnerability demonstrates the importance of maintaining up-to-date security practices and the critical need for comprehensive security testing of all web application components, particularly those handling sensitive authentication data. The ATT&CK framework categorizes this type of vulnerability under privilege escalation and credential access techniques, emphasizing the need for robust application-level security controls to prevent unauthorized access to stored credentials and system resources.
