Multiple vulnerabilities have been discovered in ProQuiz, which can be exploited by malicious users to conduct SQL injection attacks and compromise a vulnerable system and by malicious people to conduct cross-site request forgery, cross-site scripting, and SQL injection attacks.

1) Input passed via the "page" parameter to my_account.php (when "action" is set to "getpage") is not properly verified before being used to include files. This can be exploited to include arbitrary PHP files from local or remote resources.

2) Input passed via the "instid" parameter to my_account.php (when "action" is set to "answers") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

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

3) Input passed via the "email" POST parameter to functions.php (when "action" is set to "recoverpass") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

4) Input passed via the "username" POST parameter to functions.php (when "action" is set to "edit_profile" and "type" is set to "username") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

5) 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. change the administrator's password if a logged-in administrator visits a malicious web site.

The vulnerabilities are confirmed in version 2.0.2. Other versions may also be affected.
