Description:
Three different Cross Site Scripting vulnerabilities have been identified in PostNuke.
The problem is that certain input isn't verified properly. While certain malicious tags are filtered it is still possible to inject malicious scripts using tag parameters.
Examples:
/user.php?op=confirmnewuser&module=NS-NewUser&uname=%22%3E%3Cimg%20src=evil_script
/modules.php?op=modload&name=FAQ&file=index&myfaq=yes&id_cat=1&
categories=%3Cimg%20src=evil_script
/modules.php?letter=%22%3E%3Cimg%20src=evil_script
This has been reported to affect version 0.723-Phoenix
Solution:
Update to version 0.726 or later.
