[R1] phpMyAdmin Setup Script setup/frames/index.inc.php Verbose Server Name Stored XSS

Medium

Synopsis

During the analysis of PMASA-2010-5 and developing a Nesuss plugin, it was discovered that the 'Verbose server name' field in /setup/index.php does not properly sanitize user-supplied input before being passed to setup/frames/index.inc.php, leading to a stored cross-site scripting issue. After submitting the form, the input is sanitized everwhere except the 'td' tag, so it renders in the table where all servers are listed. Authentication is required for this attack.

Solution

Upgrade to 3.3.7, or later. Note that 2.11.10.1 was tested and found not vulnerable. The vendor confirmed that 2.11.x was not affected.
