CVE-2025-13086

Estado: AnalizadaMedia (4.6)—

Improper validation of source IP addresses in OpenVPN version 2.6.0 through 2.6.15 and 2.7_alpha1 through 2.7_rc1 allows an attacker to open a session from a different IP address which did not initiate the connection resulting in a denial of service for the originating client

CVSS

Probabilidad de explotación (EPSS)
