Barracuda Web Application Firewall (WAF) 7.8.1.013 allows remote attackers to bypass authentication by leveraging a permanent authentication token obtained from a query string.

Hard coded weak credentials in Barracuda Load Balancer 5.0.0.015.

Privilege escalation vulnerability in Barracuda Load Balancer 5.0.0.015 via the use of an improperly protected SSH key.

Barracuda Web Filter before 8.1.0.005, when SSL Inspection is enabled, does not verify X.509 certificates from upstream SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Barracuda Web Filter 7.x and 8.x before 8.1.0.005, when SSL Inspection is enabled, uses the same root Certification Authority certificate across different customers' installations, which makes it easier for remote attackers to conduct man-in-the-middle attacks against SSL sessions by leveraging the certificate's trust relationship.

A remote command injection vulnerability exists in the Barracuda Load Balancer product line (confirmed on v5.4.0.004 (2015-11-26) and v6.0.1.006 (2016-08-19); fixed in 6.1.0.003 (2017-01-17)) in which an authenticated user can execute arbitrary shell commands and gain root privileges. The vulnerability stems from unsanitized data being processed in a system call when the delete_assessment command is issued.

Barracuda Message Archiver 2018 has XSS in the error_msg exception-handling value for the ldap_user parameter to the cgi-mod/ldap_load_entry.cgi module. The injection point of the issue is the Add_Update module.

Authenticated, administrative access to a Barracuda Load Balancer ADC running unpatched firmware <= v6.4 allows one to edit the LDAP service configuration of the balancer and change the LDAP server to an attacker-controlled system, without having to re-enter LDAP credentials. These steps can be used by any authenticated administrative user to expose the LDAP credentials configured in the LDAP connector over the network.

The barracudavpn component of the Barracuda VPN Client prior to version 5.0.2.7 for Linux, macOS, and OpenBSD runs as a privileged process and can allow an unprivileged local attacker to load a malicious library, resulting in arbitrary code executing as root.
