CVE-2022-34186

CVE-2022-34186: Cross-site Scripting in Jenkins Dynamic Extended Choice Parameter Plugin

Jenkins Dynamic Extended Choice Parameter Plugin 1.0.1 and earlier does not escape the name and description of Moded Extended Choice parameters on views displaying parameters, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

Exploitation of this vulnerability requires that parameters are listed on another page, like the "Build With Parameters" and "Parameters" pages provided by Jenkins (core), and that those pages are not hardened to prevent exploitation. Jenkins (core) has prevented exploitation of vulnerabilities of this kind on the "Build With Parameters" and "Parameters" pages since 2.44 and LTS 2.32.2 as part of the SECURITY-353 / CVE-2017-2601 fix. Additionally, several plugins have previously been updated to list parameters in a way that prevents exploitation by default, see SECURITY-2617 in the 2022-04-12 security advisory for a list.

Root Cause Analysis

The vulnerability stems from unescaped parameter name/description fields in UI rendering. Jenkins plugins typically use Jelly templates for parameter visualization. The advisory explicitly states the plugin fails to escape these fields, which would manifest in the view templates (Jelly files) responsible for parameter display. While specific Java code isn't available, the pattern matches known XSS vulnerabilities in Jenkins plugins where parameter metadata isn't escaped during rendering.
