CVE-2018-3948

An exploitable denial-of-service vulnerability exists in the URI-parsing functionality of the TP-Link TL-R600VPN HTTP server. A specially crafted URL can cause the server to stop responding to requests, resulting in downtime for the management portal. An attacker can send either an unauthenticated or authenticated web request to trigger this vulnerability.
