Descriptions

Huawei S7700, S9300, S9700, and S12700 devices with software before V200R008C00SPC500 use random numbers with insufficient entropy to generate self-signed certificates, which makes it easier for remote attackers to discover private keys by leveraging knowledge of a certificate.

Dispositivos Huawei S7700, S9300, S9700 y S12700 con software en versiones anteriores a V200R008C00SPC500 utiliza números aleatorios con entropía insuficiente para generar certificados con auto-firma, lo que facilita a atacantes remotos descubrir claves privadas mediante el aprovechamiento del conocimiento un certificado.
