Multiple heap-based buffer overflows in Huawei Campus Series Switches S3700HI, S5700, S6700, S3300HI, S5300, S6300, S9300, S7700, and LSW S9700 with software V200R001 before V200R001SPH013; S5700, S6700, S5300, and S6300 with software V200R002 before V200R002SPH005; S7700, S9300, S9300E, S5300, S5700, S6300, S6700, S2350, S2750, and LSW S9700 with software V200R003 before V200R003SPH005; and S7700, S9300, S9300E, and LSW S9700 with software V200R005 before V200R005C00SPC300 allow remote attackers to cause a denial of service (device restart) via a crafted length field in a packet.

Stack-based buffer overflow in the HTTP module in the (1) Branch Intelligent Management System (BIMS) and (2) web management components on Huawei AR routers and S2000, S3000, S3500, S3900, S5100, S5600, S7800, and S8500 switches allows remote attackers to execute arbitrary code via a long URI.
The HTTP module in the (1) Branch Intelligent Management System (BIMS) and (2) web management components on Huawei AR routers and S2000, S3000, S3500, S3900, S5100, S5600, and S7800 switches uses predictable Session ID values, which makes it easier for remote attackers to hijack sessions via a brute-force attack.
