CVE-2020-2036

Estado: ModificadaAlta (8.8)—💥 Exploit

A reflected cross-site scripting (XSS) vulnerability exists in the PAN-OS management web interface. A remote attacker able to convince an administrator with an active authenticated session on the firewall management interface to click on a crafted link to that management web interface could potentially execute arbitrary JavaScript code in the administrator's browser and perform administrative actions. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.16; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9.

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.
