CVE-2024-47946

Estado: AplazadaAlta (7.2)—

If the attacker has access to a valid Poweruser session, remote code execution is possible because specially crafted valid PNG files with injected PHP content can be uploaded as desktop backgrounds or lock screens. After the upload, the PHP script is available in the web root. The PHP code executes once the uploaded file is accessed. This allows the execution of arbitrary PHP code and OS commands on the device as "www-data".

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, PR:H (requiere sesión Poweruser válida): T1210. Carga de PNG con PHP inyectado accesible en web root ejecuta código arbitrario como www-data (web shell T1505.003 + ejecución T1059).

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.
