Loading vulnerability…
An out-of-bounds read vulnerability exists in FreeRDP before version 2.1.2 due to improper bounds checking when accessing the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This flaw allows the software to read memory outside the intended buffer, potentially exposing sensitive information or causing a crash.

This repository contains a proof-of-concept (PoC) exploit for CVE-2020-11097, a vulnerability in FreeRDP. The main file, 'test.py', is a Python script that implements a malicious NTLM authentication server. When run, it listens on TCP port 3389 (the standard RDP port) and waits for incoming connections from RDP clients. Upon receiving an NTLM negotiation from a client, the script responds with a specially crafted NTLM Type 2 Challenge message containing a malformed AV_PAIR section designed to trigger an out-of-bounds read in the FreeRDP client, causing it to crash. The README provides instructions for running the server and connecting to it using the 'xfreerdp' client. The exploit demonstrates the vulnerability but does not provide a weaponized or post-exploitation payload. The repository is structured simply, with a single exploit script and a README file.
