CVE-2023-37019

Estado: AnalizadaAlta (8.6)—

Open5GS MME versions <= 2.6.4 contains an assertion that can be remotely triggered via a malformed ASN.1 packet over the S1AP interface. An attacker may send an `S1Setup Request` message missing a required `Supported TAs` field to repeatedly crash the MME, resulting in denial of service.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N/AC:L/PR:N permite explotación remota sin privilegios (T1190). El envío de paquetes S1AP malformados causa crash del MME (DoS por inundación de aplicación, T1499.004).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
