CVE-2017-1000091
Jenkins GitHub Branch Source Plugin vulnerable to Cross-Site Request Forgery
Also known as GHSA-w66r-f5gg-gqwm
Published 9 y ago · modified 4 mo ago · JSON
Summary
GitHub Branch Source Plugin connects to a user-specified GitHub API URL (e.g. GitHub Enterprise) as part of form validation and completion (e.g. to verify Scan Credentials are correct). This functionality improperly checked permissions, allowing any user with Overall/Read access to Jenkins to connect to any web server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery.
Exploit prediction (EPSS)
0.64% probability of exploitation in the next 30 days, higher than 51% of all scored CVEs.
