DESCRIPTION:
Kerio has acknowledged a vulnerability in Kerio Control and Kerio
WinRoute Firewall, which can be exploited by malicious people to
poison the HTTP cache.

The vulnerability is caused due to an unspecified error when
processing HTTP data sent to a "non-HTTP" TCP connection. This can be
exploited via a malicious website to e.g. store arbitrary data in the
HTTP cache, which will then be served instead of legitimate content.

Successful exploitation requires that the HTTP cache is enabled
(disabled by default).

The vulnerability is reported in all versions prior to Kerio Control
version 7.1.0 Patch 1.

SOLUTION:
Update to Kerio Control version 7.1.0 Patch 1.
