Cross-site scripting in phpMyAdmin - CVE-2016-2561

Detailed vulnerability description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via (1) normalization.php or (2) js/normalization.js in the database normalization page, (3) templates/database/structure/sortable_header.phtml in the database structure page, or (4) the pos parameter to db_central_columns.php in the central columns page. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
