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.

Rejected reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue.

Wing FTP Server 6.3.8 contains a remote code execution vulnerability in its Lua-based web console that allows authenticated users to execute system commands. Attackers can leverage the console to send POST requests with malicious commands that trigger operating system execution through the os.execute() function.

Wing FTP Server 6.0.7 contains an unquoted service path vulnerability that allows local attackers to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted binary path in the service configuration to inject malicious executables that will be launched with LocalSystem permissions.

Wing FTP Server versions prior to 6.2.7 contain a cross-site request forgery (CSRF) vulnerability in the web administration interface that allows attackers to delete admin users. Attackers can craft a malicious HTML page with a hidden form to submit a request that deletes the administrative user account without proper authorization.
