CVE-2019-16651Public exploitNetwork attack vector

WAN address disclosure via unauthenticated SNMP request

Published Sep 20, 2021 · Updated Aug 5, 2024

Information disclosure in Virgin Media Super Hub 3 devices allows remote attackers to read the WAN IP address through DNS rebinding. The browser-facing /snmpGet endpoint returns the WanCurrentIPAddr.1 OID without authentication after attacker-controlled DNS is rebound to the hub's local address. A victim must load attacker-controlled JavaScript while using an affected VPN configuration; the reported consequence is VPN decloaking, not router modification.
