Vulnerability from variot - Updated: 2023-12-18 12:53Kerio WinRoute Firewall 6.2.2 and earlier allows remote attackers to cause a denial of service (crash) via malformed DNS responses. Kerio WinRoute Firewall is prone to a remote denial-of-service vulnerability. Exploiting this issue may permit an attacker to crash affected devices, denying further network services to legitimate users. Kerio WinRoute Firewall 6.2.2 and prior versions are vulnerable; other versions may also be affected. Kerio WinRoute Firewall is a gateway firewall for small and medium businesses.
To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.
The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios.
This includes: * Reason for rating * Extended description * Extended solution * Exploit code or links to exploit code * Deep links
