DESCRIPTION:
Multiple security issues have been discovered in the Grapefile plugin
for WordPress, which can be exploited by malicious people to
compromise a vulnerable system.

The security issues are caused due to missing access restrictions to
the wp-content/plugins/grapefile/grapeupload.php,
wp-content/plugins/grapefile/grapeupload2.php,
wp-content/plugins/grapefile/grapeupload3.php, and
wp-content/plugins/grapefile/grapeupload4.php scripts. This can be
exploited to upload arbitrary files to the
"wp-content/plugins/grapefile/filestore/avi",
"wp-content/plugins/grapefile/filestore/doc",
"wp-content/plugins/grapefile/filestore/mp3", and
"wp-content/plugins/grapefile/filestore/zip" folders inside the
webroot and e.g. execute arbitrary PHP code.

The security issues are confirmed in version 1.1. Other versions may
also be affected.

SOLUTION:
Restrict access to the grapeupload.php, grapeupload2.php,
grapeupload3.php, and grapeupload4.php scripts (e.g. via .htaccess).
