Remote code execution via unsafe log formatting

Published Aug 13, 2025 · Updated Apr 7, 2026

Stack-based buffer overflow in RabidHamster R4 Embedded Server 1.25 allows remote attackers to execute code via a crafted URI. The embedded HTTP server passes an oversized query string to sprintf() while generating a log entry, overflowing a stack buffer. No authentication or user interaction is required, and successful exploitation runs code with the web server process's privileges.
