Summary

CVE-2023-50123 is a high-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Hozard Alarm System. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Password Guessing (T1110.001); ranked at the 48th percentile by exploit likelihood (below the median); 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-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-7 Unsuccessful Logon Attempts good match

AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.

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.

DE.CM-03 partial match
blocks

Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.

PR.AA-03 partial match
blocks

Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.

PR.PS-04 partial match
blocks

Generating auth logs enables later detection or forensics but does not itself restrict attempts.
