High severity, CVSS 8.1. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products

• Cerberusftp FTP Server: from 10.0.0, before 10.0.18 (fixed in 10.0.18); from 11.0.0, before 11.0.3 (fixed in 11.0.3)
