DESCRIPTION:
Charlie Eriksen has discovered multiple vulnerabilities in the Global
Content Blocks plugin for WordPress, which can be exploited by
malicious users to bypass certain security restrictions and by
malicious people to disclose potentially sensitive information.

1) The
wp-content/plugins/global-content-blocks/resources/tinymce/gcb_ajax_add.php
script does not properly verify permissions before creating code
blocks. This can be exploited to create arbitrary code blocks and
execute PHP code.

2) The
wp-content/plugins/global-content-blocks/resources/tinymce/gcbvalue.php
and wp-content/plugins/global-content-blocks/gcb/gcb_export.php
scripts does not properly restrict access, which can be exploited to
disclose the contents of code blocks.

The vulnerabilities are confirmed in version 1.5.1. Other versions
may also be affected.

SOLUTION:
Update to version 1.5.2.

PROVIDED AND/OR DISCOVERED BY:
Charlie Eriksen via Secunia.
