Description
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.

What to do
Solution: Administrators should ensure that their Barracuda Load Balancer ADC is on either a 6.3.x or 6.4.x version so that the patch can be applied through Barracuda's automated security patching system. Ensure that you have not intentionally disabled the security update system. Administrators should update their Barracuda Load Balancer ADC devices to the latest firmware versions as they become available. Version 6.5 will ship with the patch for CVE-2019-5648.
