CVE-2022-25188 : Security Advisory and Response

This article provides detailed information about CVE-2022-25188, a vulnerability affecting Jenkins Fortify Plugin versions up to 20.2.34 that allows attackers with Item/Configure permission to manipulate .xml files on the Jenkins controller file system.

Understanding CVE-2022-25188

CVE-2022-25188 is a security flaw in the Jenkins Fortify Plugin that exposes a risk of unauthorized file manipulation on the Jenkins controller file system.

What is CVE-2022-25188?

The vulnerability in Jenkins Fortify Plugin versions <= 20.2.34 arises from the lack of sanitization in the appName and appVersion parameters of Pipeline steps. This oversight permits attackers with specific permissions to write or overwrite arbitrary .xml files, leading to potential system compromise.

The Impact of CVE-2022-25188

The impact of CVE-2022-25188 includes the unauthorized modification of sensitive .xml files on the Jenkins controller file system. Attackers with Item/Configure permissions can inject malicious content into these files, bypassing control mechanisms and potentially compromising the integrity of the software development environment.

Technical Details of CVE-2022-25188

The following technical details shed light on the vulnerability's description, affected systems, and exploitation mechanism.

Vulnerability Description

Jenkins Fortify Plugin 20.2.34 and earlier fail to properly sanitize the appName and appVersion parameters, enabling attackers to write or overwrite .xml files on the Jenkins controller file system.

Affected Systems and Versions
