Title: Watchguard SOHO 2.2 Denial of Service Vulnerability
Severity: HIGH
Description:
The SOHO 2.2 is a popular SOHO firewall by Watchguard Technologies Inc.
A vulnerability exists in Watchguard SOHO 2.2 firewalls with firmware versions 2.2.1 and below that could allow a remote attacker to execute a Denial of Service attack on the firewall and render it in-operable.
It is possible for a remote attacker to issue large amounts of GET requests (70+) to the firewall which will in turn deplete memory resources on the firewall and either cause it to reboot or shutdown completely. In the case of a reboot, the firewall will be in-operable for one to five minutes. If the firewall shuts down completely, it will require a power recycle. In the case of a sustained attack, the firewall can be permanently taken off-line. It should be noted that this attack does not appear in the firewall logs except for a reboot notification.
Affected Products:
- WatchGuard SOHO 2.2.0
