Wftpserver: >> Wing Ftp Server >> 3.5.2 Security Vulnerabilities
CVE-2025-47812
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.

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."

A vulnerability has been found in Wing FTP Server up to 7.4.3 and classified as critical. Affected by this vulnerability is an unknown functionality of the component Lua Admin Console. The manipulation leads to execution with unnecessary privileges. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 7.4.4 is able to address this issue. It is recommended to upgrade the affected component. The vendor explains: "[W]e do not consider it as a security vulnerability, because the system admin in WingFTP has full permissions [...], but you can suggest the user run WingFTP service as Normal User rather than SYSTEM/Root, it will be safer."

An issue was discovered in Wing FTP Server 6.2.5 before February 2020. Due to insecure permissions when handling session cookies, a local user may view the contents of the session and session_admin directories, which expose active session cookies within the Wing FTP HTTP interface and administration panel. These cookies may be used to hijack user and administrative sessions, including the ability to execute Lua commands as root within the administration panel.
