Loading vulnerability…
An untrusted search path vulnerability exists in VLC Media Player 1.1.3 and earlier, specifically in bin/winvlc.c, where the application loads DLLs from the current working directory. This allows an attacker to place a malicious wintab32.dll in the same directory as a media file (e.g., .mp3), which VLC will load when opening the file, leading to arbitrary code execution.

This repository demonstrates DLL injection techniques and specifically targets the untrusted search path vulnerability (CVE-2010-3124) in VLC Media Player 1.1.3 and earlier on Windows. The exploit leverages the fact that VLC will load a DLL (wintab32.dll) from the same directory as a media file (e.g., .mp3) when opening it, allowing an attacker to execute arbitrary code. The repository contains two Python scripts: - `src/dll_injection.py`: Implements DLL injection using the Windows API via ctypes, automating the process of injecting a DLL into a target process by PID. - `src/injection.py`: Another variant of DLL injection, also using ctypes, with similar logic but slightly different implementation details. Both scripts are proof-of-concept code for DLL injection and are not weaponized (they do not include a malicious DLL payload). The README provides a detailed explanation of the vulnerability, attack scenario, and background on DLL injection. The main fingerprintable endpoints are the DLL filename (`wintab32.dll`) and the use of `.mp3` files to trigger the exploit. The attack vector is local, requiring the attacker to place files on the victim's system and for the victim to open the media file with VLC.
