- Description:
####################
Web Wiz NewsPad is an advanced but easy to use Email Newsletter and  
Website News Bulletin software.

####################
- Vulnerability:
####################
Input passed to the FolderName parameter in "RTE_file_browser.asp" is  
not properly sanitised before being used. This can be exploited to  
list directories, list txt and list zip files through directory  
traversal attacks.
Also, "RTE_file_browser.asp" does not check user's session and an  
unauthenticated attacker can perform this attack.

-POC:
http://[WebWiz 
NewsPad]/RTE_file_browser.asp?look=&sub=\.....\\\.....\\\.....\\\


####################
- Fast Solution :
####################

=09strSubFolderName = Replace(strSubFolderName, "../", "", 1, -1, 1)
=09strSubFolderName = Replace(strSubFolderName, "..\", "", 1, -1, 1)
=09strSubFolderName = Replace(strSubFolderName, "./", "", 1, -1, 1)
