SonicOS HTTP Request Stack-Based Buffer Overflow
CVE-2022-22274 is a stack-based buffer overflow in SonicWall SonicOS that is reachable via an HTTP request. According to the provided content, the flaw allows a remote, unauthenticated attacker to trigger memory corruption in the firewall by sending a crafted HTTP request to the affected SonicOS management interface. Successful exploitation can cause a denial of service and may potentially lead to code execution on the firewall. The specific vulnerable function, code path, and affected firmware versions are not provided in the supplied content.

Exploits

This repository provides a Python proof-of-concept (PoC) script (poc.py) for testing and exploiting two stack-based buffer overflow vulnerabilities in SonicWall SonicOS (CVE-2022-22274 and CVE-2023-0656). The exploit targets the web management interface of SonicWall NGFW devices via HTTPS, sending specially crafted HTTP GET requests with overly long URI paths to specific endpoints (/resources/, //, /atp/, /stats/, /Security_Services). The script can safely test for vulnerability or trigger a denial-of-service (DoS) by crashing the device. The README.md offers detailed background, usage instructions, and example outputs. The code is standalone, written in Python, and does not rely on external frameworks. No hardcoded IPs or domains are present; the user supplies the target. The repository is structured with a single exploit script, a README, and a license file.
