Multiple vulnerabilities have been discovered in eliteCMS, which can be exploited by malicious users to conduct script insertion and SQL injection attacks and by malicious people to conduct cross-site scripting, cross-site request forgery, and SQL injection attacks.

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

Successful exploitation allows e.g. retrieval of administrator usernames and password hashes.

2) Input passed to the "name", "sender_email", and "message" parameters of the "Contact Info" page 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) Input passed to the "page" parameter in admin/edit_page.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.

4) 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 if a logged-in administrative user visits a malicious web site.

5) Input passed via the "title", "keywords", and "description" parameters to admin/add_page.php, "title" parameter to admin/add_post.php, "first_name" and "last_name" parameters to admin/edit_user.php is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

6) Input passed via the "page" parameter to admin/add_post.php is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires prior authentication.

NOTE: This can further be exploited to conduct cross-site scripting attacks via SQL error messages.

The vulnerabilities are confirmed in version 1.01. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised. Do not browse untrusted sites or follow untrusted links while being logged-in to the application.
