Descriptions

LOYTEC LINX-212 firmware 6.2.4 and LVIS-3ME12-A1 firmware 6.2.2 and LIOB-586 firmware 6.2.3 devices lack authentication for the preinstalled version of LWEB-802 via an lweb802_pre/ URI. An unauthenticated attacker can edit any project (or create a new project) and control its GUI.

Los dispositivos LOYTEC LINX-212 firmware 6.2.4 y LVIS-3ME12-A1 firmware 6.2.2 y LIOB-586 firmware 6.2.3 carecen de autenticación para la versión preinstalada de LWEB-802 a través de un URI lweb802_pre/. Un atacante no autenticado puede editar cualquier proyecto (o crear un proyecto nuevo) y controlar su GUI.

LOYTEC LINX-151, LINX-212, LVIS-3ME12-A1, LIOB-586, LIOB-580 V2, LIOB-588, L-INX Configurator devices (all versions) lack authentication for the preinstalled version of LWEB-802 via an lweb802_pre/ URI. An unauthenticated attacker can edit any project (or create a new project) and control its GUI.
