Last modified Jun 17, 2026

CVE-2020-35221 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
