November 9, 2007
Risk Level:
HIGH - Vulnerability can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of an affected site. The elevated risk rating reflects the persistent nature of this cross-site scripting attack.
Program Summary:
phpMyAdmin is a tool written in PHP intended to handle the administration of MySQL over the Web.
http://www.phpmyadmin.net/
Cross-site Scripting Vulnerability:
When creating a new database, a malicious user can use a client-side Web proxy to place malicious code in the "db" parameter of the POST request. Since db_create.php does not properly sanitize user-supplied input, an administrator could face a persistent XSS attack when the database names are displayed.
Sample Exploit Code:
db=>%22%27><img%20src%3d%22javascript:alert(%27XSS%27)%22>
Vendor Solution:
Fixed in the SVN repository.
