Technical details
A Cross-Site Request Forgery (CSRF) vulnerability exists in OpenCart version 3.0.3.7 and potentially earlier versions. The application fails to implement security tokens (anti-CSRF tokens) for sensitive actions within the user panel. An attacker can exploit this by crafting a malicious HTML page containing a hidden form that targets the 'account/password' endpoint. When an authenticated user visits the attacker's site, the form is submitted automatically, updating the 'password' and 'confirm' parameters to a value chosen by the attacker. This results in a full account takeover. The vulnerability is reachable over the network and requires the victim to be authenticated and interact with a malicious link or site.
