CVE-2020-9067


There is a buffer overflow vulnerability in some Huawei products. The vulnerability can be exploited by an attacker to perform remote code execution on the affected products when the affected product functions as an optical line terminal (OLT). Affected product versions include:SmartAX MA5600T versions V800R013C10, V800R015C00, V800R015C10, V800R017C00, V800R017C10, V800R018C00, V800R018C10; SmartAX MA5800 versions V100R017C00, V100R017C10, V100R018C00, V100R018C10, V100R019C10; SmartAX EA5800 versions V100R018C00, V100R018C10, V100R019C10.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.0, indicating it requires adjacent network access with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 6 products from huawei, from huawei, from huawei and 3 others, organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2020, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For huawei's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
