iveresk/cve-2022-31749PoC checker for CVE-2022-31749 exploiting a parameter injection vulnerability in WatchGuard SSH interface to exfiltrate hashed user passwords via FTP.
Simple PoC-checker for CVE-2022-31749 by 1vere$k.
It exploits a parameter injection vulnerability in the WatchGuard SSH interface.
The vulnerability allows a low privileged user to exfiltrate arbitrary system files to an attacker controlled FTP server.
Fortunately, there is a builtin low privileged user named status that this script defaults to.
It isn't unreasonable to assume that the status user will use a password of readonly, but it isn't required.
The exploit exfiltrates the user file configd-hash.xml.
This file contains hashed user passwords.
The hashes are simply unsalted MD4. @funoverip described using hashcat to crack the hashes in this file all the way back in 2013
