Description
This security bulletin contains information about 1 security vulnerability.
1) Cross-site request forgery (CVE-ID: CVE-2017-1000092)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Git Plugin connects to a user-specified Git repository as part of form validation. An attacker with no direct access to Jenkins but able to guess at a username/password credentials ID could trick a developer with job configuration permissions into following a link with a maliciously crafted Jenkins URL which would result in the Jenkins Git client sending the username and password to an attacker-controlled server.
