Vulnerabilities

Insecure preserved inherited permissions vulnerability in Cerberus FTP Server on Windows allows Privilege Escalation.This issue has been resolved in Cerberus FTP Server: 2026.1

The Web Client in Cerberus FTP Server Enterprise before 10.0.19 and 11.x before 11.0.4 allows XSS via an SVG document.

Cerberus FTP Server Enterprise Edition prior to versions 11.0.3 and 10.0.18 allows an authenticated attacker to create files, display hidden files, list directories, and list files without the permission to zip and download (or unzip and upload) files. There are multiple ways to bypass certain permissions by utilizing the zip and unzip features. As a result, users without permission can see files, folders, and hidden files, and can create directories without permission.

Reflected XSS through an IMG element in Cerberus FTP Server prior to versions 11.0.1 and 10.0.17 allows a remote attacker to execute arbitrary JavaScript or HTML via a crafted public folder URL. This occurs because of the folder_up.png IMG element not properly sanitizing user-inserted directory paths. The path modification must be done on a publicly shared folder for a remote attacker to insert arbitrary JavaScript or HTML. The vulnerability impacts anyone who clicks the malicious link crafted by the attacker.

In Cerberus FTP Server 8.0.10.1, a crafted HTTP request causes the Windows service to crash. The attack methodology involves a long Host header and an invalid Content-Length header.
