CVE-2025-44896Public exploitNetwork attack vector

Unauthenticated memory corruption via crafted MAC name

Published May 20, 2025 · Updated May 21, 2025

A stack overflow in PLANET WGS-804HPT firmware 1.305b241111 allows remote attackers to corrupt memory through a crafted MAC name. The web_acl_bindEdit_post function fails to bound the bindEditMACName parameter before it overruns stack storage. Network access alone reaches the flaw; public evidence establishes memory corruption but does not establish reliable code execution beyond a service crash.
