Loading vulnerability…
An elevation of privilege vulnerability affecting Microsoft Visual Studio. Successful exploitation allows an attacker to gain higher privileges than intended within the affected environment. Publicly available context identifies the issue as a Visual Studio privilege escalation flaw, but does not provide sufficient technical detail about the vulnerable component, root cause, or triggering conditions to describe the underlying bug with confidence.

This repository is a Proof-of-Concept (PoC) exploit for CVE-2024-20656, a local privilege escalation vulnerability in the Microsoft Visual Studio DiagnosticsHub Collector Service (VSStandardCollectorService150). The exploit is implemented in C++ and consists of several source and header files, with 'main.cpp' serving as the entry point. The code orchestrates a series of file system operations, including the creation of directories, symbolic links, and junctions, to manipulate the file system in a way that abuses the privileged service. It monitors for the creation of specific files (such as 'MofCompiler.exe' in the Visual Studio SetupWMI directory), resets their permissions, and then triggers the WMI installer to execute code with elevated privileges. The exploit is designed for local execution on Windows systems where the vulnerable service is present. The repository structure is typical for a Visual Studio C++ project, with project and solution files, source code, and a brief README referencing the vulnerability and a related blog post. No network endpoints are involved; all actions are performed locally on the file system.
