CVE-2017-7881

Name of the Vulnerable Software and Affected Versions BigTree CMS versions prior to 4.2.18

Description The issue allows remote attackers to bypass CSRF protection by manipulating the HTTP Referer header. This is due to the reliance on a substring check for CSRF protection, which can be exploited by placing the required admin/developer/ URI within a query string in the Referer header. The vulnerability was found in the core/admin/modules/developer/ header.php file and was patched in the core/inc/bigtree/admin.php file.

Recommendations For BigTree CMS versions prior to 4.2.18, update to version 4.2.18 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin/developer/ URI to minimize the risk of exploitation.
