CVE-2023-35838

Name of the Vulnerable Software and Affected Versions WireGuard client version 0.5.3

Description The WireGuard client version 0.5.3 on Windows has an insecure configuration of the operating system and firewall. This configuration can block traffic to a local network using non-RFC1918 IP addresses. An attacker can exploit this to trick a user into blocking IP traffic to specific IP addresses and services, even while the VPN is active. This issue can result in disruption of access to network resources.

Recommendations Update to a newer version of the WireGuard client that addresses this firewall configuration issue.
