DescriptionCVE.org

A command injection vulnerability in the DHCP activation feature of Weintek cMT-3072XH2 easyweb Web Version v2.1.53, OS v20231011 allows attackers to execute arbitrary commands with root privileges.

Executive ViewAI

Why It Matters

A critical remote code execution vulnerability (CVE-2024-55020, CVSS 9.8) affects Weintek cMT-3072XH2 HMI devices running easyweb Web v2.1.53, enabling unauthenticated attackers to execute arbitrary commands with root privileges. Organizations deploying these industrial control devices face immediate risk of complete system compromise, data exfiltration, and operational disruption with no vendor patch currently available.

Business Impact: Severe

Compensating Controls

Disable DHCP activation feature in device configuration if business operations permit; implement network segmentation isolating cMT-3072XH2 devices to restricted VLANs with strict ingress filtering; deploy WAF rules targeting DHCP activation service endpoints with input validation; restrict administrative access via IP whitelisting; enable enhanced logging and SIEM alerting on device access patterns; monitor for CVE-2024-55020 exploitation signatures; implement network-based intrusion detection targeting command injection payloads.
