CVE-2010-20108Public exploit

Arbitrary code execution via oversized LIST response

Published Aug 21, 2025 · Updated May 15, 2026

Stack buffer overflow in FTPPad FTP Client 1.2.0 and earlier allows remote attackers to execute arbitrary code via a crafted FTP LIST reply. The directory listing parser accepts an excessively long directory and filename without validating its length, causing saved EIP to be overwritten. A user must connect the client to an attacker-controlled FTP server; the published exploit targets Windows XP SP3 and needs no further interaction.
