Description The issue is related to the use of a weak hash in the password storage mechanism, allowing a remote unauthenticated attacker to login to the product by using a password reversed from a previously eavesdropped password hash. This could potentially lead to unauthorized access to protected information.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
