Description

The disclosed vulnerability allows a remote user to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote authenticated user with Overall/Read permission can send a specially crafted HTTP request to an attacker-specified SSH server and trick the application to initiate requests to arbitrary systems, capturing credentials stored in Jenkins.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
