CVE-2010-20113Public exploitNetwork attack vector

Unauthenticated code execution via unchecked path length

Published Aug 21, 2025 · Updated May 15, 2026

Stack-based buffer overflow in KMiNT21 Software EasyFTP Server 1.7.0.11 and earlier allows remote attackers to execute code. The list.html handler accepts an overlong path query value without enforcing its size, overwriting stack-resident control-flow data. Default anonymous access exposes the HTTP interface without credentials, allowing process takeover or a service crash.
