Summary
CVE-2025-56448 is a medium-severity Authentication Bypass by Capture-replay (CWE-294) vulnerability in Positron Px360Bt Firmware. Its CVSS base score is 6.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Pass the Hash (T1550.002); ranked at the 20th 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 SC-23 (Session Authenticity) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Vulnerability Data
The Positron PX360BT SW REV 8 car alarm system is vulnerable to a replay attack due to a failure in implementing rolling code security. The alarm system does not properly rotate or invalidate used codes, allowing repeated reuse of captured…

transmissions. This exposes users to significant security risks, including vehicle theft and loss of trust in the alarm's anti-cloning claims.

Mitigating Controls (NIST 800-53 r5) AI
Session authenticity mechanisms directly stop replay of captured authentication traffic by enforcing freshness or cryptographic binding.
Transmission integrity (with anti-replay) stops captured messages from being accepted as valid later.
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.
Protecting and verifying identity assertions prevents replay of captured authentication material.
Encryption and integrity protections for data-in-transit directly block capture-replay of credentials or tokens.
Network monitoring may detect anomalous replays after the fact but does not prevent the design flaw.
Strong authentication methods can reduce replay risk but do not inherently address captured messages.
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.
Cryptographic protections (e.g., nonces, timestamps, message authentication codes) make captured authentication messages unusable for replay.
A.8.5 mandates MFA, non-cleartext transmission, session termination, brute-force protection, and log-on design that directly stops replayed sniffed credentials from succeeding; the bounded remainder is replay of non-password authenticators or post-auth session tokens not covered by the clause.
