CVE-2024-55020 is a command injection vulnerability in the DHCP activation feature of Weintek cMT-3072XH2 easyWeb Web Version v2.1.53 running on OS v20231011. It allows attackers to execute arbitrary commands with root privileges. The vulnerability is associated with CWE-20 (Improper Input Validation) and CWE-78 (OS Command Injection) and has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility and lack of prerequisites.

Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation grants root-level command execution on the affected device, potentially enabling full system compromise, data exfiltration, persistence, or further lateral movement within industrial control system environments where Weintek cMT-3072XH2 HMIs are deployed.

Mitigation details are available in the referenced advisories, including the GitHub Gist at https://gist.github.com/AenganZ/f86ed0da28825a1432ec697f484622de and the Notion page at https://plain-trick-71d.notion.site/weintek-cMT-3072XH2-14687a89c4c181eeb21ad61e0392f34b?pvs=4.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing input validation through analysis or test cases.

SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Requiring documented development standards and tools can embed input-validation practices into the engineering process.

Secure engineering principles require proper neutralization of untrusted input before command construction.

Secure SDLC practices directly require and enforce input validation during development.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).

finds

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.

prevents

Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.

prevents

Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.

prevents

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.

prevents

Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.

none

Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
