DESCRIPTION:
A weakness has been reported in the Phoca Favicon component for
Joomla!, which can be exploited by malicious, local users to
manipulate certain data and potentially gain escalated privileges.

The weakness is caused due to the component setting insecure
permissions (777) for the "images/phocafavicon" folder. This can be
exploited to e.g. modify, create, or delete files contained in the
folder.

The weakness is reported in version 2.0.2. Other versions may also be
affected.

SOLUTION:
Modify the directory permissions to restrict access.

PROVIDED AND/OR DISCOVERED BY:
Reported by the Joomla! VEL team.
