CVE-2024-22086Public exploitNetwork attack vector

Unauthenticated code execution via unbounded URI parsing

Published Jan 5, 2024 · Updated Jun 18, 2025

Stack-based buffer overflow in Cherry through commit 4b877df allows remote attackers to execute code via a long HTTP request URI. The handle_request function in http.c passes the request line to sscanf with unbounded %s conversions into fixed-size stack buffers for the method, URI, and version. Network access to a running Cherry HTTP server is sufficient; a malformed request overwrites adjacent stack memory and can crash the process or execute attacker-controlled code.
