CVE-2022-39959

Estado: ModificadaAlta (7.8)—💥 PoC

Panini Everest Engine 2.0.4 allows unprivileged users to create a file named Everest.exe in the %PROGRAMDATA%\Panini folder. This leads to privilege escalation because a service, running as SYSTEM, uses the unquoted path of %PROGRAMDATA%\Panini\Everest Engine\EverestEngine.exe and therefore a Trojan horse %PROGRAMDATA%\Panini\Everest.exe may be executed instead of the intended vendor-supplied EverestEngine.exe file.

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.
