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.

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 deleteassessment command is issued.

Multiple cross-site scripting (XSS) vulnerabilities in index.cgi in Barracuda Spam Firewall (BSF) before 3.5.12.007, Message Archiver before 1.2.1.002, Web Filter before 3.3.0.052, IM Firewall before 3.1.01.017, and Load Balancer before 2.3.024 allow remote attackers to inject arbitrary web script or HTML via (1) the Policy Name field in Search Based Retention Policy in Message Archiver; unspecified parameters in the (2) IP Configuration, (3) Administration, (4) Journal Accounts, (5) Retention Policy, and (6) GroupWise Sync components in Message Archiver; (7) input to search operations in Web Filter; and (8) input used in error messages and (9) hidden INPUT elements in (a) Spam Firewall, (b) IM Firewall, and (c) Web Filter.
