TITLE

Kerio WinRoute Firewall Multiple Denial of Service Vulnerabilities

DESCRIPTION

Multiple unspecified vulnerabilities in Kerio WinRoute Firewall before 6.1.4 Patch 1 allow remote attackers to cause a denial of service via multiple unspecified vectors involving (1) long strings received from Active Directory and (2) the filtering of HTML. Kerio WinRoute Firewall is prone to multiple denial of service vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input. An attacker can exploit these vulnerabilities to crash the affected service, effectively disabling the firewall. This may aid in further attacks. Kerio WinRoute firewall is an enterprise gateway firewall suitable for small and medium businesses. Kerio WinRoute has loopholes when processing specific HTML data, and remote attackers may use the loopholes to perform denial-of-service attacks on the firewall.
