Deeper analysis
China Mobile Intelligent Home Gateway firmware version HG6543C4 contains a design flaw in its authentication mechanism, tracked as CVE-2023-41012 and assigned CWE-384. The vulnerability permits remote attackers to bypass identity verification and execute arbitrary commands on the device. It carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low complexity, and no required privileges or user interaction.
Unauthenticated remote attackers can exploit the weakness to gain full control of affected gateways, potentially compromising home-network traffic, connected devices, and any credentials stored on the appliance. The flaw stems from inadequate session or authentication-state handling that allows crafted requests to achieve command execution without valid credentials.
Public references consist of a detailed technical disclosure on GitHub that reproduces the command-execution path resulting from the identity-verification design flaw; no vendor advisory, patch, or official mitigation guidance is referenced in the available sources. The associated EPSS score reached a peak of 0.0703 before receding to its current value of 0.0404, indicating modest post-disclosure interest that has since declined.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Session termination after a set interval shortens the usable lifetime of a fixed session identifier, making successful exploitation of session fixation more difficult.
Re-authentication typically forces issuance of a new session, limiting the window for exploitation of a previously fixed session identifier.
Enforces proper session ID generation and binding, preventing fixation of a known session token.
