admin.php in BigTree through 4.2.18 has a Cross-site Scripting (XSS) vulnerability, which allows remote authenticated users to inject arbitrary web script or HTML by launching a Home Template Edit Page action and entering the Navigation Title of a page that is scheduled for future publication (aka a pending page change).

An issue was discovered in BigTree CMS before 4.2.15. The vulnerability exists due to insufficient filtration of user-supplied data in the "id" HTTP GET parameter passed to the "core/admin/adjax/dashboard/check-module-integrity.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

SQL injection vulnerability in core\admin\auto-modules\forms\process.php in BigTree 4.2.18 allows remote authenticated users to execute arbitrary SQL commands via the tags array parameter.

A SQL injection vulnerability in core/inc/auto-modules.php in BigTree CMS through 4.2.19 allows remote authenticated attackers to obtain information in the context of the user used by the application to retrieve data from the database. The attack uses an admin/trees/add/process request with a crafted _tags[] parameter that is mishandled in a later admin/ajax/dashboard/approve-change request.

CSRF exists in BigTree CMS 4.1.18 and 4.2.16 with the id parameter to the admin/ajax/users/delete/ page. A user can be deleted.

SQL injection vulnerability in core/inc/bigtree/cms.php in BigTree CMS 4.0 RC2 and earlier allows remote attackers to execute arbitrary SQL commands via the PATH_INFO to index.php.

Cross-site request forgery (CSRF) vulnerability in core/admin/modules/users/create.php in BigTree CMS 4.0 RC2 and earlier allows remote attackers to hijack the authentication of administrators for requests that create an administrative user via an add user action to index.php.

Cross-site request forgery (CSRF) vulnerability in core/admin/modules/users/update.php in BigTree CMS 4.0 RC2 and earlier allows remote attackers to hijack the authentication of administrators for requests that modify arbitrary user accounts via an edit user action.

Cross-site scripting (XSS) vulnerability in core/admin/modules/developer/modules/views/add.php in BigTree CMS 4.0 RC2 and earlier allows remote attackers to inject arbitrary web script or HTML via the module parameter.

Cross Site Scripting vulnerability in BigTree CMS v.4.5.7 allows a remote attacker to execute arbitrary code via the ID parameter in the Developer Settings functions.

BigTree CMS 4.4.16 was discovered to contain an arbitrary file upload vulnerability which allows attackers to execute arbitrary code via a crafted PDF file.

A vulnerability has been discovered in BigTree CMS 4.4.10 and earlier which allows an authenticated attacker to execute arbitrary commands through a crafted request sent to the server via the 'Create a New Setting' function.

A stored cross-site scripting (XSS) vulnerability was discovered in BigTree CMS 4.4.10 and earlier which allows an authenticated attacker to execute arbitrary web scripts or HTML via the page content to site/index.php/admin/pages/update.

A SQL injection vulnerability was discovered in /core/feeds/custom.php in BigTree CMS 4.4.10 and earlier which allows an authenticated attacker to inject a malicious SQL query to the applications via the 'Create New Feed' function.

Cross Site Scripting (XSS) vulnerabilty exists in BigTree-CMS 4.4.3 in the tag name field found in the Tags page under the General menu via a crafted website name by doing an authenticated POST HTTP request to admin/tags/create.

Cross-site scripting (XSS) in BigTree 4.2.19 allows any remote users to inject arbitrary web script or HTML via the directory parameter. This issue exists in core/admin/ajax/developer/extensions/file-browser.php.

BigTree 4.3 allows full path disclosure via authenticated admin/news/ input that triggers a syntax error. NOTE: This has been disputed with the following reasoning: "The issue reported requires full developer level access to the content management system where cross site scripting is not an issue -- you already have full control of the CMS including running arbitrary PHP.

A Session Fixation issue was discovered in Bigtree before 4.2.24. admin.php accepts a user-provided PHP session ID instead of regenerating a new one after a user has logged in to the application. The Session Fixation could allow an attacker to hijack an admin session.

In the 4.2.23 version of BigTree, a Stored XSS vulnerability has been discovered in /admin/ajax/file-browser/upload/ (aka the image upload area).

BigTree 4.2.23 on Windows, when Advanced or Simple Rewrite routing is enabled, allows remote attackers to bypass authentication via a ..\ substring, as demonstrated by a launch.php?bigtree_htaccess_url=admin/images/..\ URI.
