Critical:

Software:Xitami 2.x

Description:
A vulnerability has been identified in Xitami allowing malicious people to cause a Denial of Service.

The problem is that Xitami fails to handle a header which is longer than 5154 characters followed by ":" when a ".shtm" file is requested. This causes Xitami to crash.

This has been reported to affect release version 2.4d9 and beta version 2.5b5.

Solution:
Use a proxy server or firewall with URL filtering capabilities to block malicious requests.
