Wing FTP Server < 7.4.4 Multiple Vulnerabilities

critical Nessus Plugin ID 241999

Language:

Synopsis

The remote FTP service is affected by multiple vulnerabilities.

Description

The remote FTP server is running a version of Wing FTP Server earlier than 7.4.4. It is, therefore, affected by multiple vulnerabilities, as follows:

 - 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. (CVE-2025-47812)

 - loginok.html in Wing FTP Server before 7.4.4 discloses the full local installation path of the application when using a long value in the UID cookie. (CVE-2025-47813)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to version 7.4.4 or later.
