Exploitation Summary

EIP tracks 4 public exploits for CVE-2012-10053. PoCs published by Metasploit, mr.pr0n, mr.pr0n, juan vazquez, including Metasploit module exploits/windows/http/sws_connection_bof.

AI-analyzed exploit summary This Metasploit module exploits a stack-based buffer overflow in Simple Web Server 2.2 rc2 via a maliciously crafted Connection header. It achieves remote code execution by overwriting the EIP and leveraging a 'call edi' instruction from libstdc++-6.dll.

Description

Simple Web Server 2.2 rc2 contains a stack-based buffer overflow vulnerability in its handling of the Connection HTTP header. When a remote attacker sends an overly long string in this header, the server uses vsprintf() without proper bounds checking, leading to a buffer overflow on the stack. This flaw allows remote attackers to execute arbitrary code with the privileges of the web server process. The vulnerability is triggered before authentication.
