DESCRIPTION:
supernothing has discovered a vulnerability in 1 Flash Gallery plugin
for WordPress, which can be exploited by malicious people to
compromise a vulnerable system.

The vulnerability is caused due to the
wp-content/plugins/1-flash-gallery/upload.php script (when "action"
is set to "uploadify" and "fileext" is set to e.g. "php") improperly
verifying uploaded files. This can be exploited to execute arbitrary
PHP code by uploading a PHP file.

The vulnerability is confirmed in version 1.5.6. Prior versions may
also be affected.

SOLUTION:
Update to version 1.5.8.
