Symmetricom SyncServer Unauthenticated Remote Command Execution

Disclosed

Description

This module exploits an unauthenticated command injection vulnerability in /controller/ping.php.
The S100 through S350 (End of Life) models should be vulnerable to
unauthenticated exploitation due to a session handling vulnerability.
Later models require authentication which is not provided in this module because we can't test it.
The command injection vulnerability is patched in the S650 v2.2 (CVE-2022-40022).
Run 'check' first to determine if vulnerable.
The server limits outbound ports. Ports 25 and 80 TCP were successfully used for SRVPORT
and LPORT while testing this module.
