Huawei switches S5700, S6700, S7700, S9700 with software V200R001C00SPC300, V200R002C00SPC100, V200R003C00SPC300, V200R005C00SPC500, V200R006C00; S12700 with software V200R005C00SPC500, V200R006C00; ACU2 with software V200R005C00SPC500, V200R006C00 have a permission control vulnerability. If a switch enables Authentication, Authorization, and Accounting (AAA) for permission control and user permissions are not appropriate, AAA users may obtain the virtual type terminal (VTY) access permission, resulting in privilege escalation.

Exploit prediction

0.79% chance of exploitation in the next 30 days, higher than 56% of all scored CVEs (FIRST EPSS, 2026-11-09).

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
