Multiple vulnerabilities have been discovered in Gazelle CMS, which can be exploited by malicious people to disclose sensitive information, conduct cross-site scripting and cross-site request forgery attacks, bypass certain security restrictions, conduct SQL injection attacks and compromise a vulnerable system.

1) Input passed to the "template" parameter in index.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.

2) Input passed to the "user" parameter in user.php and to the "lookup" parameter in search.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) The password reset functionality in renew.php does not validate the identity of a user requesting a password reset, which can be exploited to specify a new password for an existing user.

Successful exploitation requires that the username is known.

4) The application does not properly restrict access to the admin/settemplate.php script, which can be exploited to e.g. create new files containing arbitrary PHP code via specially crafted requests.

5) Access to admin/editor/filemanager/browser.html is not properly restricted. This can be exploited to upload file with multiple extensions and e.g. execute arbitrary PHP code.

Successful exploitation requires a certain server configuration (e.g. an Apache server with the "mod_mime" module installed).

6) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. create an arbitrary user with administrative privileges and conduct script insertion attacks if a logged-in administrative user visits a malicious web site.

7) Input passed to the "email", "table" and "activate" parameters in forgot.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

8) Input appended to the URL after index.php, forgot.php, and register.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

9) Input passed to the "table" parameter in register.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

10) The application does not properly restrict access to admin/extract.php and can be exploited to execute arbitrary PHP code by uploading a malicious PHP script compressed in a ZIP file.

The vulnerabilities are confirmed in version 1.0. Other versions may also be affected.
