Descriptions

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.14.1), RUGGEDCOM ROX RX1400 (All versions < V2.14.1), RUGGEDCOM ROX RX1500 (All versions < V2.14.1), RUGGEDCOM ROX RX1501 (All versions < V2.14.1), RUGGEDCOM ROX RX1510 (All versions < V2.14.1), RUGGEDCOM ROX RX1511 (All versions < V2.14.1), RUGGEDCOM ROX RX1512 (All versions < V2.14.1), RUGGEDCOM ROX RX1524 (All versions < V2.14.1), RUGGEDCOM ROX RX1536 (All versions < V2.14.1), RUGGEDCOM ROX RX5000 (All versions < V2.14.1). Affected devices write crashdumps without checking if enough space is available on the filesystem. Once the crashdump fills the entire root filesystem, affected devices fail to boot successfully. An attacker can leverage this vulnerability to cause a permanent Denial-of-Service.

Se ha identificado una vulnerabilidad en RUGGEDCOM ROX MX5000 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1400 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1500 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1501 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1510 (Todas las versiones anteriores a V2. 14.1), RUGGEDCOM ROX RX1511 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1512 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1524 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX1536 (Todas las versiones anteriores a V2.14.1), RUGGEDCOM ROX RX5000 (Todas las versiones anteriores a V2.14.1). Los dispositivos afectados escriben crashdumps sin comprobar si presentan suficiente espacio disponible en el sistema de archivos. Una vez que el crashdump llena todo el sistema de archivos root, los dispositivos afectados no pueden arrancar con éxito. Un atacante puede aprovechar esta vulnerabilidad para causar una Denegación de Servicio permanente
