CVE-2022-31479 CRITICAL

Published: 2022-06-06 | Last Modified: 2024-11-21 | Status: Modified

Description

An unauthenticated attacker can update the hostname with a specially crafted name that will allow for shell commands to be executed during the core collection process. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable. The injected commands only get executed during start up or when unsafe calls regarding the hostname are used. This allows the attacker to gain remote access to the device and can make their persistence permanent by modifying the filesystem.

Additional Descriptions (1)

Un atacante no autenticado puede actualizar el nombre de host con un nombre especialmente diseñado que permitirá una ejecución de comandos de shell durante el proceso de recogida del núcleo. Esta vulnerabilidad afecta a los productos basados en los controladores inteligentes HID Mercury LP1501, LP1502, LP2500, LP4502 y EP4502 que contienen versiones de firmware anteriores a 1.302 para la serie LP y 1.296 para la serie EP. Un atacante con este nivel de acceso en el dispositivo puede monitorear todas las comunicaciones enviadas hacia y desde este dispositivo, modificar los relés de la placa, cambiar los archivos de configuración o causar que el dispositivo se vuelva inestable. Los comandos inyectados sólo son ejecutados durante el arranque o cuando son usadas llamadas no seguras en relación con el nombre del host. Esto permite al atacante conseguir acceso remoto al dispositivo y puede hacer que su persistencia sea permanente al modificar el sistema de archivos
