Background
phpMyAdmin is a popular open-source tool for managing MySQL databases. It provides a web-based interface that allows users to perform various database management tasks. This vulnerability affects versions 4.0.x, 4.1.x, and 4.2.x of phpMyAdmin. The vulnerability allows remote authenticated users to inject arbitrary web script or HTML through crafted database or table names. The issue is present in the code responsible for SQL debug output and the server monitor page.
Vulnerability Detail
The vulnerability in phpMyAdmin allows an attacker with authenticated access to inject malicious script or HTML code through specially crafted database or table names. This can lead to cross-site scripting (XSS) attacks, where the injected code is executed in the context of other users accessing the affected pages. The impact of this vulnerability can range from stealing sensitive information, such as login credentials, to performing actions on behalf of the victim user.

Workaround
If upgrading to the latest version is not immediately possible, a temporary workaround can be implemented by sanitizing user input for database and table names. This can be done by implementing proper input validation and filtering to prevent the injection of malicious code. Here is an example of how to sanitize user input in PHP:
$databaseName = filter_var($_POST['database_name'], FILTER_SANITIZE_STRING);
$tableName = filter_var($_POST['table_name'], FILTER_SANITIZE_STRING);
By using the FILTER_SANITIZE_STRING filter, any potentially harmful characters will be removed from the input.
Conclusion
The phpMyAdmin implementation XSS vulnerability on the server monitor page can allow remote authenticated users to inject arbitrary web script or HTML. This can lead to cross-site scripting attacks and potential unauthorized access to sensitive information. It is recommended to upgrade to the latest version of phpMyAdmin (4.0.10.5, 4.1.14.6, or 4.2.10.1) to fix this vulnerability. If immediate upgrade is not possible, implementing proper input validation and filtering can serve as a temporary workaround.
