CVE-2026-24848

Estado: AnalizadaAlta (8.7)—

OpenEMR is a free and open source electronic health records and medical practice management application. In 7.0.4 and earlier, the disposeDocument() method in EtherFaxActions.php allows authenticated users to write arbitrary content to arbitrary locations on the server filesystem. This vulnerability can be exploited to achieve Remote Code Execution (RCE) by uploading malicious PHP web shells.

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 autenticado (PR:L) sin interacción a método que permite escritura arbitraria de archivos en servidor OpenEMR, permitiendo inyectar web shells PHP para RCE.

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.
