An XSS issue was discovered in Wing FTP 6.4.4. An arbitrary IFRAME element can be included in the help pages via a crafted link, leading to the execution of (sandboxed) arbitrary HTML and JavaScript in the user's browser.

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.

Wing FTP Server v6.2.3 for Linux, macOS, and Solaris sets insecure permissions on files modified within the HTTP file management interface, resulting in files being saved with world-readable and world-writable permissions. If a sensitive system file were edited this way, a low-privilege user may escalate privileges to root.

Wing FTP Server v6.2.3 for Linux, macOS, and Solaris sets insecure permissions on installation directories and configuration files. This allows local users to arbitrarily create FTP users with full privileges, and escalate privileges within the operating system by modifying system files.

Multiple cross-site request forgery (CSRF) vulnerabilities in Wing FTP Server before 4.4.7 allow remote attackers to hijack the authentication of administrators for requests that (1) execute arbitrary code via a crafted request to admin_lua_script.html or (2) add a domain administrator via a crafted request to admin_addadmin.html.

Wing FTP Server before 4.1.1 allows remote authenticated users to cause a denial of service (daemon crash) via two zip commands.
