Vulnerability from github – Published: 2022-05-24 17:30 – Updated: 2023-10-27 11:58

Summary

XXE vulnerability in Jenkins Nerrvana Plugin

Details

Jenkins Nerrvana Plugin 1.02.06 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers with Overall/Read permission to have Jenkins parse a crafted HTTP request with XML data that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Additionally, XML parsing is exposed as a form validation endpoint that does not require POST requests, allowing exploitation by users without Overall/Read permission via CSRF.

Severity

6.5 (Medium)
