VAR-202103-0257
Vulnerability from variot - Updated: 2023-12-18 13:22The 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. NETGEAR JGS516PE and GS116E There are cryptographic strength vulnerabilities in the device.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. NETGEAR JGS516PE/GS116Ev2 is a 16-port gigabit intelligent network management Plus switch.
NETGEAR JGS516PE/GS116Ev2 2.6.0.43 version has security vulnerabilities. Allow external attackers to gain administrative access to the switch
