Glossword contains a flaw that allows a remote Cross-site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application does not require multiple steps or explicit confirmation for sensitive transactions for the gw_admin.php script. By using a crafted URL (e.g., a crafted GET request inside an "img" tag), an attacker may trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into disclosing a user's database in the context of their session with the application, without further prompting or verification.
