Summary
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.
Exploit prediction
0.83% chance of exploitation in the next 30 days, higher than 57% of all scored CVEs (FIRST EPSS, 2026-11-09).
