Summary
A remote attacker who does not need to log in can take over a GINA account in SEPPmail Secure Email Gateway that was created but never registered and still has an empty initial password. The attacker can set a new password, sign in as that account, and lock the intended recipient out until the account is recovered.
Read the original description
SEPPmail Secure Email Gateway before 15.1.1 permits password recovery for a created but unregistered GINA account whose initial password is empty without adequately verifying ownership. A remote unauthenticated attacker who identifies such an account can set a new password, authenticate as that account, and prevent the intended recipient from using it until recovery.
What to do
Upgrade to a fixed version: 15.1.1.
