CVE-2016-6670 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.83% chance of exploitation in the next 30 days.
