Summary

CVE-2024-12137 is a high-severity Authentication Bypass by Capture-replay (CWE-294) vulnerability in Gov (inferred from references). Its CVSS base score is 7.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Remote Service Session Hijacking (T1563); ranked at the 3.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-23 (Session Authenticity) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Remote Service Session Hijacking (T1563). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

Directly requires mechanisms like nonces, timestamps, or challenge-response to protect communication session authenticity against capture-replay attacks enabling session hijacking.

SI-2 Flaw Remediation good match

prevent

Ensures timely identification, testing, and installation of software patches to remediate the specific authentication bypass vulnerability fixed in ANKA JPD-00028 V.01.01.

IA-11 Re-authentication partial match

prevent

Mandates re-authentication for session re-establishment or specific events, limiting the impact and duration of potential session hijacking via replay.

MITRE ATT&CK Enterprise TechniquesAI

T1563 Remote Service Session Hijacking Lateral Movement

Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.

Why these techniques?

The vulnerability enables capture-replay attacks resulting in session hijacking on the affected device, directly facilitating Remote Service Session Hijacking (T1563) by allowing replay of captured authentication data to take control of sessions.

Deeper analysisAI

CVE-2024-12137 is an Authentication Bypass by Capture-replay vulnerability in the Elfatek Elektronics ANKA JPD-00028 device, enabling session hijacking. This flaw affects ANKA JPD-00028 versions prior to V.01.01 and is rated with a CVSS v3.1 base score of 7.6 (AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H), mapped to CWE-294 (Authentication Bypass by Capture-replay).

An attacker with adjacent network access (AV:A) can exploit this vulnerability with low complexity (AC:L) and no required privileges (PR:N), though it necessitates user interaction (UI:R). Successful exploitation allows session hijacking, resulting in low confidentiality impact (C:L), high integrity impact (I:H), and high availability impact (A:H), potentially compromising the device's authentication mechanisms.

The Turkish National Cyber Incident Response Center (USOM) has issued an advisory on this issue at https://www.usom.gov.tr/bildirim/tr-25-0071, which security practitioners should consult for additional details on detection and response.
