The zip API endpoint in Cerberus FTP Server 8 allows an authenticated attacker without zip permission to use the zip functionality via an unrestricted API endpoint. Improper permission verification occurs when calling the file/ajax_download_zip/zip_name endpoint. The result is that a user without permissions can zip and download files even if they do not have permission to view whether the file exists.

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.

The wp-cerber plugin before 2.7 for WordPress has XSS via the X-Forwarded-For HTTP header.

Buffer overflow in Cerberus FTP Server 8.0.10.3 allows remote attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact via a long MLST command.

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.

Multiple cross-site scripting (XSS) vulnerabilities in the administrative web interface in Cerberus FTP Server before 5.0.6.0 allow (1) remote attackers to inject arbitrary web script or HTML via a log entry that is not properly handled within the Log Manager component, and might allow (2) remote authenticated administrators to inject arbitrary web script or HTML via a Messages field to the servermanager program.

Multiple cross-site request forgery (CSRF) vulnerabilities in the web interface in Cerberus FTP Server before 5.0.5.0 allow remote attackers to hijack the authentication of administrators for requests that (1) add a user account or (2) reconfigure the state of the FTP service, as demonstrated by a request to usermanager/users/modify.

The default configuration of Cerberus FTP Server before 5.0.4.0 supports the DES cipher for SSH sessions, which makes it easier for remote attackers to obtain sensitive information by sniffing the network and performing a brute-force attack on the encrypted data.

Cerberus FTP Server before 4.0.3.0 allows remote authenticated users to list hidden files, even when the "Display hidden files" option is enabled, via the (1) MLSD or (2) MLST commands.

Cerberus Helpdesk before 4.0 (Build 600) allows remote attackers to obtain sensitive information via direct requests for "controllers ... that aren't standard helpdesk pages," possibly involving the (1) /display and (2) /kb URIs.
