Description Adam Mariš 2018-06-28 05:35:22 EDT

A form action method in GitHub Plugin did not check the permission of the user accessing it, allowing anyone with Overall/Read access to Jenkins to cause Jenkins to send a GitHub API request to create an API token to an attacker-specified URL.

This allowed users with Overall/Read access to Jenkins to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Additionally, this form validation method did not require POST requests, resulting in a CSRF vulnerability.
