CVE-2023-32560

Estado: ModificadaCrítica (9.8)—💥 Exploit

An attacker can send a specially crafted message to the Wavelink Avalanche Manager, which could result in service disruption or arbitrary code execution.

Thanks to a Researcher at Tenable for finding and reporting.

Fixed in version 6.4.1.

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.
