DESCRIPTION:
RedTeam Pentesting has discovered a vulnerability in Owl Intranet
Engine, which can be exploited by malicious people to bypass certain
security restrictions.

The lib/owl.lib.php script does not terminate execution for
unauthenticated sessions for certain values of the "userid"
parameter, which can be exploited to perform administrative actions
via direct HTTP requests without being authenticated.

Successful exploitation requires that the guest account is disabled,
and that an administrator is included in the "Administrators" group
or a user is set to "News Administrator".

The vulnerability is confirmed in version 0.96. Other versions may
also be affected.

SOLUTION:
Upgrade to version 1.01.

PROVIDED AND/OR DISCOVERED BY:
RedTeam Pentesting.
