The devices are vulnerable to an authentication bypass due to flaws in the authorization mechanism. An unauthenticated remote attacker could exploit this weakness by performing brute-force attacks to guess valid credentials or by using MD5 collision techniques to forge authentication hashes, potentially compromising the device.
The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack).
