Creating a honeypot for CVE-2021-41773 (Path Traversal and RCE)

A path traversal vulnerability and exploit just dropped in the wild for a specific version of Apache (Apache/2.4.49). This vulnerability allows an unauthenticated attacker to execute a path traversal attack (and now shown RCE if MOD_CGI is enabled) to read files outside of the virtual directory path bounds. This only affects a single version of Apache, there’s a fair few of these online, however it’s very unlikely all are vulnerable. The vulnerability requires specific permissions to be configured.
