CVE-2025-41068

Estado: ModificadaAlta (8.7)—

Reachable Assertion vulnerability in Open5GS up to version 2.7.6 allows attackers with connectivity to the NRF to cause a denial of service. This is achieved by sending the creation of an NF with an invalid type via SBI and then requesting its data. The NRF executes a check that crashes the process, leaving the discovery service unresponsive.

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.

Vulnerabilidad de aserción alcanzable en servicio de red (NRF) accesible remotamente sin autenticación (PR:N, UI:N). Envío de mensaje SBI malformado causa crash del proceso, negando el servicio (VA:H, SA:L, aplicación protocol).

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.
