Source: CVE Program / CVE List V5
Vulnerability Description
In Wing FTP Server before 7.4.4. the user and admin web interfaces mishandle '\0' bytes, ultimately allowing injection of arbitrary Lua code into user session files. This can be used to execute arbitrary system commands with the privileges of the FTP service (root or SYSTEM by default). This is thus a remote code execution vulnerability that guarantees a total server compromise. This is also exploitable via anonymous FTP accounts.

II. Public POCs for CVE-2025-47812

# POC Description Source Link Shenlong Link
1 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. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2025/CVE-2025-47812.yaml POC Details
