CVE-2022-31262

Estado: ModificadaAlta (7.8)—💥 PoC

An exploitable local privilege escalation vulnerability exists in GOG Galaxy 2.0.46. Due to insufficient folder permissions, an attacker can hijack the %ProgramData%\GOG.com folder structure and change the GalaxyCommunication service executable to a malicious file, resulting in code execution as SYSTEM.

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.
