Loading vulnerability…
A flaw in the protection mechanism of the Palo Alto Networks Cortex XDR agent on Windows allows a local user to disable the agent. This undermines the intended security controls provided by the agent, potentially exposing the system to further compromise.

This repository is a Proof-of-Concept (PoC) exploit demonstrating a Denial of Service (DoS) vulnerability affecting several Windows EDR (Endpoint Detection and Response) agents, including Palo Alto Networks Cortex XDR (Traps). The exploit works by registering a specific ALPC (Advanced Local Procedure Call) port in the Windows Object Manager namespace (\\RPC Control\\Palo-Alto-Networks-Traps-DB-Rpc) before the EDR agent initializes. If the EDR agent attempts to create or access this IPC object and finds it already registered, its user-mode components crash, effectively disabling the EDR protection until the next reboot. The exploit is implemented in a single C++ file (ALPC-Block-POC.cpp) and is intended to be run as a low-privileged user during early system startup, such as via a scheduled task. The README provides detailed background, usage instructions, and references to relevant CVEs. No network endpoints are involved; the attack vector is local, targeting the Windows IPC mechanism. The repository is structured as a Visual Studio C++ project with supporting solution and configuration files.
