CVE-2017-20245Public exploitNetwork attack vector

Unauthenticated database reads via unescaped POST parameter

Published Jun 9, 2026 · Updated Jun 9, 2026

SQL injection in Wow-Company Wow Viral Signups 2.1 allows remote attackers to read arbitrary database data via a crafted POST request. The mwp_signup_send action accepts idsignup at wp-admin/admin-ajax.php and places the unescaped value in a MySQL WHERE or HAVING expression. No authentication or user interaction is required; successful requests expose database contents, while filesystem access depends on web-server misconfiguration.
