CVE-2011-5331

This exploit targets a remote code execution vulnerability in Distributed Ruby (dRuby) by leveraging instance_eval and syscall methods to execute arbitrary commands. It attempts multiple techniques, including direct command injection and syscall-based file creation/execution, to achieve RCE on both 32-bit and 64-bit systems.

This exploit leverages Ruby's DRb (Distributed Ruby) to achieve remote code execution by bypassing instance_eval restrictions. It connects to a vulnerable DRb server and executes arbitrary commands via a shell.
