CVE-2022-34183: 
Java vulnerability analysis and mitigation

Jenkins Agent Server Parameter Plugin 1.1 and earlier contains a stored cross-site scripting (XSS) vulnerability identified as CVE-2022-34183. The vulnerability was discovered and disclosed on June 22, 2022, affecting the plugin's parameter handling functionality. The issue affects all versions up to and including version 1.1 of the Agent Server Parameter Plugin (Jenkins Advisory).

The vulnerability stems from the plugin's failure to escape the name and description of Agent Server parameters on views displaying parameters. This creates a stored cross-site scripting (XSS) vulnerability that can be exploited by attackers who have Item/Configure permission. The vulnerability has been assigned a CVSS v3.1 base score of 5.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N (NVD).

The vulnerability allows attackers with Item/Configure permission to inject malicious HTML and JavaScript code into parameter views. When other users view these parameters, the injected code executes in their browsers, potentially leading to session hijacking, credential theft, or other client-side attacks (Jenkins Advisory).

As of the advisory's publication date, there was no fix available for the Agent Server Parameter Plugin. Users should consider implementing access control restrictions to limit Item/Configure permissions to trusted users only. Additionally, the vulnerability's impact is partially mitigated by Jenkins core's built-in protections against parameter-based XSS attacks on the 'Build With Parameters' and 'Parameters' pages (Jenkins Advisory).
