zawhttpd Buffer Overflow Exploit

This exploit attempts to kill zawhttpd by sending a malicious GET request to the server. The malicious request contains a large number of backslashes which can cause a buffer overflow and crash the server.

Mitigation:

Ensure that the server is running the latest version of zawhttpd and that all security patches are up to date.
