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, S7800, and S8500 switches does not check whether HTTP data is longer than the value of the Content-Length field, which allows remote HTTP servers to conduct heap-based buffer overflow attacks and execute arbitrary code via a crafted response.

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.
