Simple PoC-checker for CVE-2022-31749 by 1vere$k

介绍

# CVE-2022-31749 by 1vere$k
Simple PoC-checker for CVE-2022-31749 by 1vere$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](https://web.archive.org/web/20160522043540/http://funoverip.net/2013/09/cracking-watchguard-passwords/) using hashcat to crack the hashes in this file all the way back in 2013
