Progress WS_FTP Server < 8.7.4, 8.8.0 < 8.8.2 Multiple Vulnerabilities

critical Nessus Plugin ID 182521


The remote FTP server is affected by multiple vulnerabilities.


The remote host is running a version of WS_FTP earlier than 8.7.4 or 8.8.0 prior to 8.8.2. Such versions are reportedly affected by multiple vulnerabilities :

- A pre-authenticated attacker could leverage a .NET deserialization vulnerability in the Ad Hoc Transfer module to execute remote commands on the underlying WS_FTP Server operating system. (CVE-2023-40044)

- A directory traversal vulnerability was discovered. An attacker could leverage this vulnerability to perform file operations (delete, rename, rmdir, mkdir) on files and folders outside of their authorized WS_FTP folder path. Attackers could also escape the context of the WS_FTP Server file structure and perform the same level of operations (delete, rename, rmdir, mkdir) on file and folder locations on the underlying operating system. (CVE-2023-42657)

- A reflected cross-site scripting (XSS) vulnerability exists in WS_FTP Server's Ad Hoc Transfer module.
An attacker could leverage this vulnerability to target WS_FTP Server users with a specialized payload which results in the execution of malicious JavaScript within the context of the victims browser.

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


Upgrade to WS_FTP Server version 8.7.4, 8.8.2 or later.
