Background
The Jenkins HashiCorp Vault Plugin is a Maven package (com.datapipe.jenkins.plugins:hashicorp-vault-plugin) that provides functionality for integrating Jenkins with HashiCorp Vault. This plugin allows users to securely retrieve and manage secrets stored in Vault from within Jenkins. It is commonly used in CI/CD pipelines to access sensitive information such as API keys, passwords, and certificates. However, versions 3.8.0 and earlier of the plugin contain a security vulnerability that enables agent processes to bypass the controller's security measures and retrieve any Vault secrets. This means that attackers who can control agent processes can obtain Vault secrets for a specified path and key, potentially leading to unauthorized access and misuse of sensitive information.
Vulnerability Detail
The vulnerability (CVE-2022-25186) in the Jenkins HashiCorp Vault Plugin allows agent processes to retrieve any Vault secrets for use on the agent. This security bypass occurs due to a flaw in the plugin's implementation, which does not properly enforce access controls for agent processes. As a result, attackers who can control agent processes can exploit this vulnerability to obtain Vault secrets for an attacker-specified path and key. The impact of this vulnerability is significant as it allows unauthorized access to sensitive information stored in Vault, potentially leading to data breaches, privilege escalation, and other malicious activities.
