In Progress WSFTP Server before 8.8, it is possible for a host administrator to elevate their privileges via the administrative interface due to insufficient authorization controls applied on user modification workflows.

Reflected XSS (via AngularJS sandbox escape expressions) exists in Progress Ipswitch WSFTP Server 8.6.0. This can lead to execution of malicious code and commands on the client due to improper handling of user-provided input. By inputting malicious payloads in the subdirectory searchbar or Add folder filename boxes, it is possible to execute client-side commands. For example, there is Client-Side Template Injection via subFolderPath to the ThinClient/WtmApiService.asmx/GetFileSubTree URI.

In WSFTP Server version prior to 8.8.2,

an unauthenticated user could enumerate files under the 'WebServiceHost' directory listing.

In WSFTP Server version prior to 8.8.2, a stored cross-site scripting (XSS) vulnerability exists in WSFTP Server's Management module. An attacker with administrative privileges could import a SSL certificate with malicious attributes containing cross-site scripting payloads.  Once the cross-site scripting payload is successfully stored,  an attacker could leverage this vulnerability to target WSFTP Server admins with a specialized payload which results in the execution of malicious JavaScript within the context of the victims browser.

In WSFTP Server versions prior to 8.7.4 and 8.8.2,

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

In WSFTP Server versions prior to 8.7.4 and 8.8.2, 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 WSFTP folder path.  Attackers could also escape the context of the WSFTP Server file structure and perform the same level of operations (delete, rename, rmdir, mkdir) on file and folder locations on the underlying operating system.

In WSFTP Server versions prior to 8.7.4 and 8.8.2,

a SQL injection vulnerability exists in the WSFTP Server manager interface. An attacker may be able to infer information about the structure and contents of the database and execute SQL statements that alter or delete database elements.

In WSFTP Server version prior to 8.8.2,

the WSFTP Server Manager interface was missing cross-site request forgery (CSRF) protection on a POST transaction corresponding to a WSFTP Server administrative function.

In WSFTP Server versions before 8.8.8 (2022.0.8), a Missing Critical Step in Multi-Factor Authentication of the Web Transfer Module allows users to skip the second-factor verification and log in with username and password only.

In WSFTP Server versions before 8.8.8 (2022.0.8), an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Web Transfer Module allows File Discovery, Probe System Files, User-Controlled Filename, Path Traversal.

An authenticated file download flaw has been identified where a user can craft an API call that allows them to download a file from an arbitrary folder on the drive where that user host's root folder is located (by default this is C:)

In WSFTP Server versions prior to 8.7.6 and 8.8.4, an unrestricted file upload flaw has been identified. An authenticated Ad Hoc Transfer user has the ability to craft an API call which allows them to upload a file to a specified location on the underlying operating system hosting the WSFTP Server application.

Buffer overflow in Ipswitch WSFTP Server with SSH 6.1.0.0 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a long opendir command.

A Directory Traversal issue was discovered in SSHServerAPI.dll in Progress ipswitch WSFTP Server 2018 before 8.6.1. An attacker can supply a string using special patterns via the SCP protocol to disclose WSFTP usernames as well as filenames.
