Description The issue is related to the use of a password hash instead of the password for authentication, allowing a remote unauthenticated attacker to login to the product by replaying an eavesdropped password hash. This may enable an attacker to gain unauthorized access to protected information.

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