Estado: Pendiente de análisisAlta (8.2)—

The following Poly Voice IP devices, CCX, Trio, and Edge E, might be inoperable if they connect to a malicious SIP server and receive malformed data. HP is releasing updates to mitigate these potential vulnerabilities.

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.

Acceso remoto a red sin privilegios (AV:N/PR:N) contra servidores SIP. VA:H indica DoS de disponibilidad. Recepción de datos malformados causa inoperabilidad.

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.
