CVE-2020-35221

The hashing algorithm implemented for NSDP password authentication on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was found to be insecure, allowing attackers (with access to a network capture) to quickly generate multiple collisions to generate valid passwords, or infer some parts of the original.
