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 product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
