CVE-2022-30959Network attack vector

Credential theft via unchecked SSH connection endpoint

Published May 17, 2022 · Updated Aug 3, 2024

Missing authorization in Jenkins SSH Plugin 2.6.1 and earlier allows remote authenticated users to capture stored Jenkins credentials. A plugin HTTP endpoint accepts an attacker-specified SSH server and credentials ID without checking authorization, then uses the selected stored credential for the outbound connection. Overall/Read permission and prior knowledge of a valid credentials ID are required, and the attacker-controlled SSH server receives the credential material used by Jenkins.
