CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-39225 is a critical-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Gl-Inet Mt6000 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
GL-iNet routers including the AR750, AR750S, AR300M, MT300N-V2, B1300, MT1300, SFT1200, X750 (v4.3.11), MT3000, MT2500, AXT1800, AX1800, A1300, X300B (v4.5.16), XE300 (v4.3.16), E750 (v4.3.12), AP1300, S1300 (v4.3.13), and XE3000/X3000 (v4.4) contain a remote code execution vulnerability tracked as CVE-2024-39225. The flaw carries a CVSS 9.8 score reflecting network-accessible, unauthenticated attack conditions and maps to CWE-307, improper restriction of excessive authentication attempts.
An unauthenticated attacker with network access can exploit the weakness to bypass the login mechanism and execute arbitrary code on the device, resulting in full compromise of the affected router. The supplied reference details the login bypass technique used to reach code execution.
EPSS scores have reached a peak of 0.4653 with a current value of 0.4453, indicating sustained exploitation interest after public disclosure. The issue was published via GL.iNet's own CVE repository on GitHub.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces limits on unsuccessful logon attempts to block the authentication bypass (CWE-307) that enables unauthenticated RCE.
Requires the system to enforce authentication and access-control policies before permitting any code-execution paths on the router.
Restricts remote network access methods and requires additional controls that would have blocked the unauthenticated network attack vector.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.
Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.
Generating auth logs enables later detection or forensics but does not itself restrict attempts.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
CAPTCHA, account lock-out after repeated failures, and alerts on excessive attempts directly stop automated brute-force guessing of credentials.
