Loading vulnerability…
Multiple buffer overflow vulnerabilities exist in iMatix Xitami Web Server 2.5c2, specifically in the xigui32.exe and xitami.exe executables. These vulnerabilities are triggered by sending a long If-Modified-Since HTTP header, which can overflow internal buffers and allow for the execution of arbitrary code.

This repository contains a single Metasploit module (modules/exploits/windows/http/xitami_if_mod_since.rb) that exploits a stack buffer overflow vulnerability in the iMatix Xitami Web Server (version 2.5c2) on Windows. The vulnerability is triggered by sending an overly long 'If-Modified-Since' HTTP header, allowing remote code execution via a custom payload. The exploit uses the Egghunter technique to bypass size constraints and can deliver any Metasploit-compatible payload. The module includes detection logic to check for the presence of Xitami, and supports multiple return addresses for different vulnerable processes (xigui32.exe and xitami.exe). The attack vector is network-based, targeting TCP port 80. The exploit is operational and can be used to gain remote access to vulnerable systems.
