CVE-2019-14530

Estado: ModificadaAlta (8.8)—💥 Exploit

An issue was discovered in custom/ajax_download.php in OpenEMR before 5.0.2 via the fileName parameter. An attacker can download any file (that is readable by the user www-data) from server storage. If the requested file is writable for the www-data user and the directory /var/www/openemr/sites/default/documents/cqm_qrda/ exists, it will be deleted from server.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
