Opengear console servers with firmware before 2.2.1 allow remote attackers to bypass authentication, and modify settings or access connected equipment, via unspecified vectors.

Opengear console server firmware releases prior to 4.5.0 have a stored XSS vulnerability related to serial port logging. If a malicious user of an external system (connected to a serial port on an Opengear console server) sends crafted text to a serial port (that has logging enabled), the text will be replayed when the logs are viewed. Exploiting this vulnerability requires access to the serial port and/or console server.
