Description

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.

Affected products

Opengear: before 4.5.0 — fixed in 4.5.0

Upgrade to a fixed version: Opengear 4.5.0. Check the vendor advisory for mitigations.
