CVE-2016-6670


TITLE

plural Huawei Vulnerability of obtaining private key in device software

Trust: 0.8

sources: JVNDB: JVNDB-2016-004560

DESCRIPTION

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. HuaweiS7700 is an intelligent routing switch of China Huawei. An insecure random number generation vulnerability exists in several Huawei products. The following products and versions are affected: Huawei S7700, S9300, S9700, and versions earlier than S12700 V200R008C00SPC500
