CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2012-6570 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
