CVE-2021-47817

Estado: ModificadaMedia (4.8)—

OpenEMR 5.0.2.1 contains a cross-site scripting vulnerability in user profile parameters that authenticated attackers can chain with a file upload to achieve remote code execution. Attackers can exploit the vulnerability by crafting a malicious payload to download and execute a web shell, enabling remote command execution on the vulnerable OpenEMR instance.

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).
