CVE-2024-12830

Estado: AnalizadaAlta (7.3)—

Arista NG Firewall custom_handler Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Arista NG Firewall. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the custom_handler method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of the www-data user. Was ZDI-CAN-24019.

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 remota sin autenticación en servicio web (AV:N, PR:N, UI:N). Directory traversal (CWE-22) permite RCE como www-data. Impactos: ejecución de código arbitrario y acceso a archivos del servidor.

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.
