Name of the Vulnerable Software and Affected Versions: Huawei MBB (Mobile Broadband) products E5771h-937 versions before E5771h-937TCPU-V200R001B328D62SP00C1133 Huawei MBB (Mobile Broadband) products E5771h-937 versions before E5771h-937TCPU-V200R001B329D05SP00C1308

Description: The issue allows an attacker to launch a Denial of Service (DoS) attack by sending a special http request to the device. This causes the webserver process to consume excessive memory, resulting in the device becoming unresponsive.

Recommendations: For versions before E5771h-937TCPU-V200R001B328D62SP00C1133, update to a version after E5771h-937TCPU-V200R001B328D62SP00C1133 to resolve the issue. For versions before E5771h-937TCPU-V200R001B329D05SP00C1308, update to a version after E5771h-937TCPU-V200R001B329D05SP00C1308 to resolve the issue. As a temporary workaround, consider restricting access to the webserver process to minimize the risk of exploitation.
