DESCRIPTION:
Gerry Chng and Claudean Zheng have reported a vulnerability in
Metadot Portal Server, which can be exploited by malicious users to
gain escalated privileges.

The vulnerability is caused due to an error in "Group.pm" where
certain global variables are not properly cleared. This can be
exploited to gain access to the "SITE_MGR" group.

Successful exploitation allows the user to carry out certain
administrative tasks (e.g. modify site content), but requires
knowledge of various fields to alter and the group identification
number of the "SITE_MGR" group.

The vulnerability has been reported in version 6.4.4. Other versions
may also be affected.

SOLUTION:
Update to version 6.4.5.
