Executive Summary

The vulnerability exists in the Jenkins Credentials Binding Plugin version 720.v3f6decef43ea_ and earlier. It occurs because the plugin does not properly sanitize file names for file and zip file credentials. This flaw allows attackers who can provide credentials to a Jenkins job to write files to arbitrary locations on the node's filesystem.

If Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node, this vulnerability can be exploited to write files anywhere on the node, potentially leading to remote code execution.

Impact Analysis

This vulnerability can have serious impacts including unauthorized file writes to arbitrary locations on the Jenkins node filesystem.

If exploited, it can lead to remote code execution, allowing an attacker to run malicious code on the Jenkins server with the privileges of the Jenkins process.

This can compromise the integrity and security of the Jenkins environment and potentially the broader network or systems connected to it.

Compliance Impact

The vulnerability in Jenkins Credentials Binding Plugin allows attackers with the ability to provide credentials to a job to write files to arbitrary locations on the node filesystem, potentially leading to remote code execution. This unauthorized access and potential execution of arbitrary code can result in the compromise of sensitive data and system integrity.

Such a security breach can impact compliance with common standards and regulations like GDPR and HIPAA, which require the protection of sensitive data and the implementation of adequate security controls to prevent unauthorized access and data breaches.

Therefore, organizations using affected versions of the plugin may face increased risk of non-compliance due to potential data exposure or system compromise stemming from this vulnerability.

Mitigation Strategies

To mitigate this vulnerability, you should update the Jenkins Credentials Binding Plugin to a version later than 720.v3f6decef43ea_. This update addresses the improper sanitization of file names for file and zip file credentials, preventing attackers from writing files to arbitrary locations on the node filesystem.

Additionally, review and restrict permissions so that low-privileged users cannot configure file or zip file credentials used for jobs running on the built-in node, as this configuration can lead to remote code execution.
