CVE-2020-28391

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-200RNA switch family (All versions < V3.2.7). Devices create a new unique key upon factory reset, except when used with C-PLUG. When used with C-PLUG the devices use the hardcoded private RSA-key shipped with the firmware-image. An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.

Se ha identificado una vulnerabilidad en la familia de switches SCALANCE X-200 (incluyendo Variantes SIPLUS NET) (Todas las versiones anteriores a la versión V5.2.5), familia de switches SCALANCE X-200IRT (incluyendo la variante SIPLUS NET) (Todas las versiones anteriores a la versión V5.5.0). Los dispositivos crean una nueva clave única tras el restablecimiento de fábrica, excepto cuando se usan con C-PLUG. Cuando se usa con C-PLUG, los dispositivos usan la clave RSA privada embebida que se envía con la imagen del firmware. Un atacante podría aprovechar esta situación en una situación de man-in-the-middle y descifrar el tráfico capturado previamente
