CVE-2024-4157 is a PHP Object Injection vulnerability in the Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder for WordPress. Affected versions are all versions up to and including 5.1.15. The issue is caused by deserialization of untrusted input in the extractDynamicValues function, allowing an authenticated attacker to supply crafted serialized data and cause arbitrary PHP objects to be instantiated. On its own, the vulnerability enables object injection; if a usable POP chain exists in the WordPress environment through another installed plugin or theme, the issue may be escalated to arbitrary file deletion, sensitive data disclosure, or code execution.

This repository contains a Python exploit (exploit.py) and a README.md for CVE-2024-4157, targeting Havoc C2 version 0.7. The exploit chains a Server-Side Request Forgery (SSRF) with a Remote Code Execution (RCE) vulnerability to achieve a reverse shell on the C2 server. The attacker provides the target C2 server's URL, internal IP/port, valid credentials, and their own IP/port for the reverse shell. The exploit works by spoofing agent registration and socket communication with the C2 teamserver, then injecting a reverse shell command via a crafted payload. The README provides usage instructions, example commands, and credits. The main exploit logic is in exploit.py, which handles encryption, agent registration, socket operations, and payload delivery. The exploit is operational and provides a working reverse shell if the target is vulnerable and credentials are valid. Several network and file endpoints are fingerprintable, including the C2 server URL, internal IPs, and Windows file paths used in the payload.
