TITLE

Advantech EKI-132x Vulnerabilities that bypass authentication in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2015-006784

DESCRIPTION

Advantech EKI-132x devices with firmware before 2015-12-31 allow remote attackers to bypass authentication via unspecified vectors. Advantech EKI-132x The device firmware contains a vulnerability that prevents authentication.Authentication may be bypassed by a third party. The Advantech EKI-132x is a serial device networking server from Advantech, Inc., which provides a variety of redundant configurations and multiple access configurations for remote monitoring of serial devices over Ethernet communication protocols.
