Shellshock HTTP Exploit Attempt

Shellshock is a remote code execution (RCE) vulnerability in the Bourne-Again shell (Bash) that attackers have been exploiting since 2014. An attacker sends an HTTP request with a Shellshock payload to a vulnerable device. The payload includes code with a syntax similar to () { :;}; <exploit command>. The malicious command runs in Bash and creates a shell. The attacker connects to the shell to remotely run commands on the victim.
