The issue is fixed in version 3.2.1; sites on affected versions should update now. Disclosed September 2014, reported by Mallory Adams.
Vulnerability Overview
Cross-site request forgery (CSRF) vulnerability in the Login Widget With Shortcode (login-sidebar-widget) plugin before 3.2.1 for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the custom_style_afo parameter on the login_widget_afo page to wp-admin/options-general.php.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Login Widget With Shortcode < 3.2.1 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Login Widget With Shortcode the fix is 3.2.1: builds < 3.2.1 are affected, anything from 3.2.1 onward is not.
Remediation
Update to version 3.2.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Login Widget With Shortcode: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Login Widget With Shortcode 3.2.1 closes this, and updating the plugin is the step that ends it.
