CVE-2020-2147Network attack vector

Credential capture via CSRF-triggered SSH connection

Published Mar 9, 2020 · Updated Aug 4, 2024

CSRF in Jenkins Mac Plugin 1.1.0 and earlier allows remote attackers to send stored credentials to an attacker-controlled SSH server. The form-validation endpoint accepts GET requests and invokes FormUtils.verifyConnection with attacker-supplied host and credential identifiers. A logged-in Jenkins user must load the forged request; the resulting outbound SSH authentication exposes the selected stored credential to the attacker.
