CVE-2024-9950 affects Forescout SecureConnector v11.3.07.0109 on Windows. The provided information indicates that the product uses an insecure temporary directory in a way that allows an unauthenticated user to modify compliance scripts. Based on the available description, the flaw stems from unsafe handling of temporary files or directories used to store or stage compliance scripts, enabling unauthorized modification of those scripts before they are consumed or executed by the product. Specific vulnerable functions, code paths, and exact script execution context are not provided in the available content.

This repository is a proof-of-concept (PoC) exploit for CVE-2024-9950, a local privilege escalation vulnerability in Forescout SecureConnector for Windows (versions <= 11.3.07). The exploit targets insecure permissions in a temporary directory used by the SecureConnector agent. The main script (CVE-2024-9950-PoC.ps1) uses PowerShell's FileSystemWatcher to monitor the temp directory for the creation of .bat files. When a targeted .bat file is created, the script renames the original, replaces it with a malicious 'chain_1.bat', and executes it. The payload (chain_1.bat and chain_1.ps1) writes a marker and the output of 'whoami' to a file in C:\Temp, demonstrating code execution with escalated privileges. The repository contains three code files: the main PoC PowerShell script, a batch file launcher, and a PowerShell payload. The attack vector is local, requiring access to the Windows system where SecureConnector is installed. No network endpoints are involved; all actions are performed via the filesystem.
