CVE-2016-5804

Estado: ModificadaCrítica (9.8)—

Moxa MGate MB3180 before 1.8, MGate MB3280 before 2.7, MGate MB3480 before 2.6, MGate MB3170 before 2.5, and MGate MB3270 before 2.7 use weak encryption, which allows remote attackers to bypass authentication via a brute-force series of guesses for a parameter value.
