Cross-site scripting in phpMyAdmin - CVE-2014-8958

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 a crafted (1) database, (2) table, or (3) column name that is improperly handled during rendering of the table browse page; a crafted ENUM value that is improperly handled during rendering of the (4) table print view or (5) zoom search page; or (6) a crafted pma_fontsize cookie that is improperly handled during rendering of the home 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.
