CVE-2020-35801

Estado: ModificadaAlta (7.3)—

Certain NETGEAR devices are affected by incorrect configuration of security settings. This affects JGS516PE before 2.6.0.48, JGS524Ev2 before 2.6.0.48, JGS524PE before 2.6.0.48, and GS116Ev2 before 2.6.0.48. A TFTP server was found to be active by default. It allows remote authenticated users to update the switch firmware.
