DESCRIPTION:
James Bercegay has discovered a vulnerability in e107, which can be
exploited by malicious people to conduct SQL injection attacks and
compromise a vulnerable system.

The vulnerability is caused due to the insecure use of the
"extract()" function in download.php, which allows input passed via
the POST method to overwrite arbitrary variables. This can be
exploited to modify certain SQL statements and execute arbitrary PHP
code.

The vulnerability is confirmed in version 0.7.11. Other versions may
also be affected.

SOLUTION:
Fixed in the CVS repository.
