  * Advisory ID: DRUPAL-SA-CONTRIB-2009-042
  * Project: Submitted By (third-party module)
  * Version: 6.x
  * Date: 2009-July-15
  * Security risk: Less critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

-------- DESCRIPTION  
---------------------------------------------------------

Submitted By is a module to let you control the format of the "Submitted by"
information on your content per content type. This module does not properly
escape user input used in building the string to display the "submitted by"
text. Only administrators with the 'administer content types' permission can
enter this text. A user with this administrative privileges could attempt a
cross site scripting [1] (XSS) attack which may lead to the user gaining full
administrative access. In general, the permission "administer content types"
is comparable in scope to the "administer site configuration" permission.
Only grant this permission to trusted site administrators. See:
http://drupal.org/node/372836
