Description:
Javier Munoz has reported two weaknesses in Kerio WinRoute Firewall, Kerio MailServer and Kerio Personal Firewall, which can be exploited by malicious people to potentially cause a DoS (Denial of Service) and brute force passwords.
1) An error in the remote administration protocol, where multiple login attempts can be performed over a single connection, can be exploited to brute force passwords if the username is known.
2) An error in the remote administration protocol in the handling of certain repeated pre-authentication protocol messages, may be exploited to cause a vulnerable system to consume a large amount of CPU resources by continuously sending specially crafted messages.
The weaknesses affect the following versions:
* Kerio WinRoute Firewall version 6.0.10 and prior.
* Kerio MailServer version 6.0.8 and prior.
* Kerio Personal Firewall version 4.1.2 and prior.
