Wing FTP Server <= 7.4.3 - Remote Code Execution
Wing FTP Server versions prior to 7.4.4 are vulnerable to an unauthenticated remote code execution (RCE) flaw (CVE-2025-47812). The vulnerability arises from improper NULL byte handling in the 'username' parameter during login, which allows Lua code injection into session files. These injected session files are executed when accessing authenticated endpoints such as /dir.html, resulting in arbitrary command execution with elevated privileges. This attack is possible only when anonymous login is enabled on the server.
