The TeleMessage service through 2025-05-05 relies on MD5 for password hashing, which opens up various attack possibilities (including rainbow tables) with low computational effort.
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).
