Description

This security bulletin contains information about 1 vulnerability.

1) Cross-site request forgery (CVE-ID: CVE-2017-1000092)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: 7.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

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.

Remediation

Install update from vendor's website.
