WordPress Plugin Banners Lite - 'wpbanners_show.php' HTML Injection

source: https://www.securityfocus.com/bid/58671/info

The Banners Lite plugin for WordPress is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
