The root cause of this vulnerability is that an unauthenticated remote attacker can access the Common Gateway Interface (CGI) and use a crafted User-Agent HTTP header to execute commands on the server. This vulnerability is similar to the Shellshock vulnerability (CVE-2014-6271).

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.
