How to fix

Fixed in: 15.1.1

Technical details

The vulnerability combines insufficient LDAP filter escaping in account lookups with missing validation in the password recovery workflow. An unauthenticated remote attacker can discover GINA accounts lacking a password and initiate password recovery without verifying the account holder's identity, allowing account takeover. The fix escapes LDAP filter values and restricts password recovery to registered users with configured security questions.
