     Advisory: phpMyAdmin - error.php XSS Vulnerability
 Release Date: 2006/11/02
Last Modified: 2006/11/02
Author: Stefan Esser [] 

  Application: phpMyAdmin <=
     Severity: XSS vulnerability in an error displaying script
         Risk: Medium Critical
Vendor Status: Vendor has a released an updated version


Quote from 
   "phpMyAdmin is a tool written in PHP intended to handle the 
   administration of MySQL over the Web. Currently it can create and 
   drop databases, create/drop/alter tables, delete/edit/add fields, 
   execute any SQL statement, manage keys on fields, manage privileges,
   export data into various formats and is available in 50 languages."

   It was discovered that phpMyAdmin comes with a script to display
   error messages that supports displaying the error in a user supplied 
   charset. Unfortunately the encoding of the error message is not 
   taking the charset into account which can result into XSS when UTF-7 
   is selected. (Other charsets like US-ASCII can also be used to 
   exploit this in some browsers.)
   To trigger this XSS vulnerability an attacker just needs to call 
   the error displaying script with charset=utf-7 and utf-7 encoded
   HTML tags in the error message.

Proof of Concept:

   The Hardened-PHP Project is not going to release exploits for
   this vulnerability to the public.
