TITLE

WatchGuard SOHO deformity TCP Package can cause a denial of service attack vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-200208-113

DESCRIPTION

Watchguard SOHO firewall before 5.0.35 allows remote attackers to cause a denial of service (crash and reboot) when SOHO forwards a packet with bad IP options. WatchGuard SOHO Firewall is a firewall appliance intended for use by Home Office/Small Office users. It offers built-in VPN capabilities. WatchGuard SOHO Firewall crashes when handling certain types of malformed TCP packets. All current connections will drop when this occurs. It should be noted that this is only an issue for packets that are forwarded by the firewall appliance. It runs under the Windows operating system platform. The firewall may crash the program due to improper parsing and restart. This vulnerability exists only when the firewall allows the packet forwarding function to be enabled. For example, there are WEB services behind the firewall that may be affected by this vulnerability
