Background
The Jenkins CRX Content Package Deployer Plugin is a Maven-based plugin that allows users to deploy CRX content packages in Jenkins. It provides functionality for managing and deploying content packages to Adobe Experience Manager (AEM) instances. The plugin is widely used in Jenkins environments for automating the deployment process of AEM applications.
Vulnerability Detail
The Jenkins CRX Content Package Deployer Plugin version 1.9 and earlier is vulnerable to a stored cross-site scripting (XSS) attack. The plugin fails to properly escape the name and description of CRX Content Package Choice parameters when displaying them on certain views. This vulnerability can be exploited by attackers with Item/Configure permission. To exploit this vulnerability, the parameters need to be listed on pages like 'Build With Parameters' and 'Parameters' pages provided by Jenkins. If these pages are not hardened to prevent exploitation, an attacker can inject malicious scripts into the parameter values, leading to potential XSS attacks. Jenkins (core) has addressed similar vulnerabilities in the past, but this specific plugin version remains vulnerable.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, users can manually sanitize the parameter values by escaping special characters and removing any potentially malicious scripts. However, this workaround is not recommended as it requires manual intervention and may not provide complete protection against XSS attacks. It is strongly advised to apply the official fix by upgrading the plugin to the latest version.
Conclusion
The Jenkins CRX Content Package Deployer Plugin version 1.9 and earlier is vulnerable to a stored XSS attack. To mitigate the risk, users should upgrade to version 1.10 or later. It is crucial to keep software up to date and follow security best practices to minimize the risk of exploitation.
