CVE-2025-27724

Estado: ModificadaCrítica (9.8)—

A privilege escalation vulnerability exists in the login.php functionality of meddream MedDream PACS Premium 7.3.3.840. A specially crafted .php file can lead to elevated capabilities. An attacker can upload a malicious file to trigger this vulnerability.

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.

CVSS AV:N PR:N UI:N indica exposición remota sin privilegios. Upload de archivo .php en login.php sugiere ejecución de código remoto escalable a privilegios (T1068) y potencial web shell (T1505.003).

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.
