Descriptions

There is insecure algorithm vulnerability in Huawei products. A module uses less random input in a secure mechanism. Attackers can exploit this vulnerability by brute forcing to obtain sensitive message. This can lead to information leak. Affected product versions include:USG9500 versions V500R001C30SPC200, V500R001C60SPC500,V500R005C00SPC200;USG9520 versions V500R005C00;USG9560 versions V500R005C00;USG9580 versions V500R005C00.

Se presenta una vulnerabilidad de algoritmo no seguro en unos productos Huawei. Un módulo usa una entrada poco aleatoria en un mecanismo seguro. Unos atacantes pueden explotar esta vulnerabilidad mediante fuerza bruta para obtener mensajes confidenciales. Esto puede conllevar a un filtrado de información. Las versiones de producto afectadas incluyen: USG9500 versiones V500R001C30SPC200, V500R001C60SPC500, V500R005C00SPC200; USG9520 versiones V500R005C00; USG9560 versiones V500R005C00; USG9580 versiones V500R005C00
