Background
The DotCi Plugin is a plugin for Jenkins, an open-source automation server. It provides support for Continuous Integration and Continuous Deployment (CI/CD) pipelines. The DotCi Plugin allows users to define their CI/CD workflows using YAML configuration files (.ci.yml). These files are stored in the source code management (SCM) system and are executed by Jenkins during the build process. The plugin is vulnerable to a remote code execution (RCE) vulnerability that can be exploited by attackers who can modify the .ci.yml files in the SCM.
Vulnerability Detail
The vulnerability in the DotCi Plugin arises from its YAML parser not being properly configured to prevent the instantiation of arbitrary types. This allows attackers to inject malicious code into the .ci.yml files, which is then executed by Jenkins during the build process. As a result, an attacker with the ability to modify these files can execute arbitrary code on the Jenkins server, potentially leading to further compromise of the system. The vulnerability has a CVSS score of 8.8, indicating a high severity level.
How To Fix
