Description

F5 FirePass contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when an invalid login attempt is made in the login page at 'my.activation.php'. If the username exists in the local LDAP user directory, a slightly different error message will be displayed than in the case of a non-existent username. This will enable an attacker to enumerate valid usernames, resulting in a loss of confidentiality.
