DESCRIPTION:
OS Reviews has reported a vulnerability in AWStats, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "migrate" parameter isn't properly sanitised
before being used in an "open()" call. This can be exploited to
inject and execute arbitrary shell commands via the "|" pipe
character.

Successful exploitation requires that "AllowToUpdateStatsFromBrowser"
is enabled (not default setting).
 
The vulnerability has been reported in versions 6.5 and 6.4. Prior
versions may also be affected.

SOLUTION:
The vulnerability has been fixed in version 6.6.
