CVE-2023-47564

Estado: ModificadaAlta (8.1)—💥 PoC

An incorrect permission assignment for critical resource vulnerability has been reported to affect Qsync Central. If exploited, the vulnerability could allow authenticated users to read or modify the resource via a network.

We have already fixed the vulnerability in the following versions: Qsync Central 4.4.0.15 ( 2024/01/04 ) and later Qsync Central 4.3.0.11 ( 2024/01/11 ) and later

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.
