Official Description
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.
Technical Analysis
CVE-2015-0961 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
