CVE-2016-15031Public exploitNetwork attack vector

Unauthenticated SQL injection via unbound username

Published May 6, 2023 · Updated Aug 6, 2024

SQL injection in Ipoelnet PHP-Login 1.0 allows remote attackers to manipulate database queries through the myusername POST parameter. The checkLogin function inserts myusername directly into a SQL WHERE clause in login/scripts/class.loginscript.php instead of binding it as a prepared-statement parameter. Remote attackers require only access to the login endpoint, and the demonstrated boolean-based blind query permits database-content inference through response differences.
