WordPress Subscribe2 "subject" and "searchterm" Cross-Site Scripting Vulnerabilities


Description   Two vulnerabilities have been discovered in the Subscribe2 plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed via the "subject" parameter to wp-admin/admin.php (when "page" is set to "s2_posts") is not properly sanitised in wp-content/plugins/subscribe2/admin/send_email.php before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed via the "searchterm" parameter to wp-admin/admin.php (when "page" is set to "s2_tools") is not properly sanitised in wp-content/plugins/subscribe2/admin/subscribers.php before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities are confirmed in version 8.1. Prior versions may also be affected.
