What is CVE-2020-35783?

Certain NETGEAR Smart Managed Plus Switches are susceptible to a vulnerability due to insufficient access control at the function level. This allows unauthenticated remote attackers to exploit the NSDP protocol, enabling them to send specific read requests and obtain sensitive switch configuration parameters without any authentication. Affected models include JGS516PE, GS116Ev2, JGS524Ev2, and JGS524PE, all running firmware versions prior to 2.6.0.48. It is crucial for users to update their devices to safeguard against unauthorized access.
