CVE-2025-44952

Estado: AnalizadaAlta (7.8)—

A missing length check in `ogs_pfcp_subnet_add` function from PFCP library, used by both smf and upf in open5gs 2.7.2 and earlier, allows a local attacker to cause a Buffer Overflow by changing the `session.dnn` field with a value with length greater than 101.

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.

Buffer overflow local (AV:L, PR:L) permite escalada de privilegios y ejecución de código. CWE-120 y descripción explícita de overflow en función PFCP causa arbitrariedad en memoria, viabilizando RCE o DoS.

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.
