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 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.
