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.

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.

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.

BigTree CMS 4.2.23 allows remote authenticated users, if possessing privileges to set hooks, to execute arbitrary code via /core/admin/auto-modules/forms/process.php.

BigTree-CMS contains a Cross Site Scripting (XSS) vulnerability in /users/create that can result in The low-privileged users can use this vulnerability to attack high-privileged(Developer) users.. This attack appear to be exploitable via no. This vulnerability appears to have been fixed in after commit b652cfdc14d0670c81ac4401ad5a04376745c279.

BigTree before 4.2.22 has XSS in the Users management page via the name or company field.

site/index.php/admin/trees/add/ in BigTree 4.2.22 and earlier allows remote attackers to upload and execute arbitrary PHP code because the BigTreeStorage class in core/inc/bigtree/apis/storage.php does not prevent uploads of .htaccess files.

An issue was discovered in BigTree 4.2.22. There is cross-site scripting (XSS) in /core/inc/lib/less.php/test/index.php because of a $_SERVER['REQUEST_URI'] echo, as demonstrated by the dir parameter in a file=charsets action.

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.

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.

Cross-site scripting (XSS) vulnerabilities in BigTree CMS through 4.2.18 allow remote authenticated users to inject arbitrary web script or HTML via the description parameter. This issue exists in core\admin\ajax\pages\save-revision.php and core\admin\modules\pages\revisions.php. Low-privileged (administrator) users can attack high-privileged (Developer) users.

SQL injection vulnerability in BigTree CMS through 4.2.18 allows remote authenticated users to execute arbitrary SQL commands via core/admin/modules/developer/modules/views/create.php. The attacker creates a crafted table name at admin/developer/modules/views/create/ and the injection is visible at admin/ajax/auto-modules/views/searchable-page/ or admin/modules_name.

Multiple cross-site scripting (XSS) vulnerabilities in BigTree CMS through 4.2.18 allow remote authenticated users to inject arbitrary web script or HTML by uploading a crafted package, triggering mishandling of the (1) title or (2) version or (3) author_name parameter in manifest.json. This issue exists in core\admin\modules\developer\extensions\install\unpack.php and core\admin\modules\developer\packages\install\unpack.php. NOTE: the vendor states "You must implicitly trust any package or extension you install as they all have the ability to write PHP files.

BigTree CMS through 4.2.18 allows remote authenticated users to execute arbitrary code by uploading a crafted package containing a PHP web shell, related to extraction of a ZIP archive to filename patterns such as cache/package/xxx/yyy.php. This issue exists in core\admin\modules\developer\extensions\install\unpack.php and core\admin\modules\developer\packages\install\unpack.php. NOTE: the vendor states "You must implicitly trust any package or extension you install as they all have the ability to write PHP files.

BigTree CMS through 4.2.18 allows remote authenticated users to conduct SQL injection attacks via a crafted tables object in manifest.json in an uploaded package. This issue exists in core\admin\modules\developer\extensions\install\process.php and core\admin\modules\developer\packages\install\process.php. NOTE: the vendor states "You must implicitly trust any package or extension you install as they all have the ability to write PHP files.

BigTree CMS through 4.2.18 has CSRF related to the core\admin\modules\users\profile\update.php script (modify user information), the index.php/admin/developer/packages/delete/ URI (remove packages), the index.php/admin/developer/upgrade/ignore/?versions= URI, and the index.php/admin/developer/upgrade/set-ftp-directory/ URI.

A directory traversal vulnerability exists in core\admin\ajax\developer\extensions\file-browser.php in BigTree CMS through 4.2.18 on Windows, allowing attackers to read arbitrary files via ..\ sequences in the directory parameter.

SQL injection vulnerability in BigTree CMS through 4.2.18 allows remote authenticated users to execute arbitrary SQL commands via core\admin\modules\developer\modules\designer\form-create.php. The attacker creates a crafted table name at admin/developer/modules/designer/ and the injection is visible at admin/dashboard/vitals-statistics/integrity/check/?external=true.

Multiple CSRF issues exist in BigTree CMS through 4.2.18 - the clear parameter to core\admin\modules\dashboard\vitals-statistics\404\clear.php and the from or to parameter to core\admin\modules\dashboard\vitals-statistics\404\create-301.php.

BigTree CMS through 4.2.18 does not prevent a user from deleting their own account. This could have security relevance because deletion was supposed to be an admin-only action, and the admin may have other tasks (such as data backups) to complete before a user is deleted.

Unrestricted File Upload exists in BigTree CMS through 4.2.18: if an attacker uploads an 'xxx.pht' or 'xxx.phtml' file, they could bypass a safety check and execute any code.

CSRF exists in BigTree CMS through 4.2.18 with the force parameter to /admin/pages/revisions.php - for example: /admin/pages/revisions/1/?force=false. A page with id=1 can be unlocked.

BigTree CMS through 4.2.17 relies on a substring check for CSRF protection, which allows remote attackers to bypass this check by placing the required admin/developer/ URI within a query string in an HTTP Referer header. This was found in core/admin/modules/developer/_header.php and patched in core/inc/bigtree/admin.php on 2017-04-14.

Unrestricted File Upload exists in BigTree CMS before 4.2.17: if an attacker uploads an 'xxx.php[space]' file, they could bypass a safety check and execute any code.
