CVE-2020-2034

Estado: ModificadaAlta (8.1)—💥 PoC

An OS Command Injection vulnerability in the PAN-OS GlobalProtect portal allows an unauthenticated network based attacker to execute arbitrary OS commands with root privileges. An attacker requires some knowledge of the firewall to exploit this issue. This issue can not be exploited if GlobalProtect portal feature is not enabled. This issue impacts PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; all versions of PAN-OS 8.0 and PAN-OS 7.1. Prisma Access services are not impacted by this vulnerability.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 7.15%
Percentil entre todas las CVEs puntuadas: 94
Fecha de la puntuación: 7/10/2026

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.
