DarkFig has discovered some vulnerabilities in Tr Forum, which can be exploited by malicious people to conduct SQL injection attacks and bypass certain security restrictions.

1) Missing authentication verification in admin/insert_admin.php can be exploited to create an administrator account with limited privileges.

2) Input passed to the "id2" parameter in admin/editer.php isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires certain administrative privileges.

3) Missing access verification when updating the profile can be exploited to modify other users' settings by changing the "id" parameter.

A combination of vulnerabilities #1 and #2 can be exploited to access the administrative section with full privileges.

The vulnerabilities have been confirmed in version 2.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised and verified, and restrict access to the admin/insert_admin.php script.
