Wing Ftp Server

Wing FTP Server 8.1.2 contains an authenticated remote code execution vulnerability in the session serialization mechanism that allows authenticated administrators to inject arbitrary Lua code through the domain admin mydirectory field. Attackers can exploit unsafe serialization of session values into Lua source code without proper escaping of closing delimiters, causing the injected code to be executed when the poisoned session is loaded via loadfile().

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. [CVSS 4.3 MEDIUM]

Wing Ftp Server versions up to 6.0.7 contains a vulnerability that allows attackers to potentially execute arbitrary code with elevated system privileges (CVSS 7.8).

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. [CVSS 8.8 HIGH]

Wing FTP Server before 7.4.4 contains a critical remote code execution vulnerability (CVE-2025-47812, CVSS 10.0) through null byte injection in user/admin web interfaces that enables arbitrary Lua code execution in session files. With EPSS 92.7% and KEV listing, this vulnerability guarantees unauthenticated root/SYSTEM code execution on affected servers, as the FTP service runs with maximum privileges by default.

In Wing FTP Server through 7.4.4, the administrative web interface (listening by default on port 5466) runs as root or SYSTEM by default. The web application itself offers several legitimate ways to execute arbitrary system commands (i.e., through the web console or the task scheduler), and they are automatically executed in the highest possible privilege context. Because administrative users of the web interface are not necessarily also system administrators, one might argue that this is a privilege escalation. (If a privileged application role is not available to an attacker, CVE-2025-47812 can be leveraged.) NOTE: the vendor reportedly considers this behavior "fine to keep."
