Authentication Token Vulnerability in NETGEAR Switches

CVE-2020-35229

Summary

The vulnerability involves the improper handling of authentication tokens in NETGEAR ProSafe Plus Switches, specifically the JGS516PE and GS116Ev2 models. This flaw allows an attacker with access to network traffic to reuse authentication tokens for NSDP write requests, ultimately granting them administrative privileges without the need for valid credentials. The issue arises due to the failure to invalidate old tokens, which can pose significant risks in network environments.
