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.

Huawei AR routers with software before V200R007C00SPC100; Quidway S9300 routers with software before V200R009C00; S12700 routers with software before V200R008C00SPC500; S9300, Quidway S5300, and S5300 routers with software before V200R007C00; and S5700 routers with software before V200R007C00SPC500 make it easier for remote authenticated administrators to obtain and decrypt passwords by leveraging selection of a reversible encryption algorithm.
