CVE-2024-57520

Estado: ModificadaCrítica (9.8)—

Insecure Permissions vulnerability in asterisk v22 allows a remote attacker to execute arbitrary code via the action_createconfig function. NOTE: this is disputed by the Supplier because the impact is limited to creating empty files outside of the Asterisk product directory (aka directory traversal) and the attack can only be performed by a privileged user who has the ability to manage the configuration.

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.

AV:N/AC:L/PR:N indica exposición remota sin privilegios previos (T1190). CWE-732 es permisos inseguros; impacto T1222 (modificación permisos/atributos). La traversal permite crear ficheros fuera del directorio Asterisk (T1565.001: manipulación de datos/ficheros).

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.
