CVE-2025-41067

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. An SBI request that deletes the NRF's own registry causes a check that ends up crashing the NRF process and renders the discovery service unavailable.

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) expuesto sin autenticación (PR:N, UI:N); ataque remoto que causa caída del proceso y denial of service de aplicación.

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.
