Loading vulnerability…
A stack-based buffer overflow vulnerability exists in the HTTP packet-parsing functionality of the LIVE555 RTSP server library version 0.92. The vulnerability is triggered by a specially crafted HTTP packet, which can overflow a stack buffer and allow for arbitrary code execution. The flaw resides in the way the server parses incoming HTTP packets, failing to properly validate input lengths before copying data to a stack buffer.

This repository contains a proof-of-concept (PoC) exploit for CVE-2018-4013, a vulnerability in WECON PLC Editor V1.3.5 and prior. The main file, 'cve-2018-4013.py', is a Python script that connects to a user-specified IP and port, then sends a specially crafted HTTP GET request with an oversized 'Accept' header (filled with 1500 'a' characters). The intent is to trigger a buffer overflow or similar flaw in the target service's HTTP header parsing. The script does not provide a post-exploitation payload or shell; it is designed to demonstrate the vulnerability's existence. The README provides references and a brief description, but the exploit code is self-contained and focused on the initial trigger. No hardcoded endpoints are present; the target is specified at runtime. The attack vector is network-based, requiring the attacker to reach the vulnerable service over TCP.
This repository provides a proof-of-concept (PoC) exploit for CVE-2018-4013, a stack-based buffer overflow in the LIVE555 RTSPServer's HTTP header parsing code. The exploit is implemented in a single Python script (PoC.py), which connects to a specified IP and port, then sends a specially crafted HTTP request with multiple large 'Accept:' headers. This triggers the vulnerable code path in the server, potentially leading to remote code execution. The README.md provides a detailed technical analysis of the vulnerability, including code snippets from the LIVE555 source and an explanation of the buffer overflow mechanism. The exploit is network-based, targeting the RTSP-over-HTTP interface (commonly on TCP ports 80, 8000, or 8080). The repository is structured simply, with the main exploit logic in PoC.py, a README.md with vulnerability details, and a .gitignore file. No payload for post-exploitation is included; the PoC demonstrates the crash/overflow condition.
