High-Tech Bridge has discovered multiple vulnerabilities in TCExam, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to conduct cross-site scripting attacks.

1) Input passed to the "cid" and "uids" parameters in admin/code/tce_select_users_popup.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.

2) Input passed via the "user_groups[]" parameter to admin/code/tce_edit_test.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.

The vulnerabilities are confirmed in version 11.3.008. Prior versions may also be affected.

Solution
Update to version 11.3.009.
