- 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 :
####################
You can see below lines in "RTE_file_browser.asp"

	'Stip path tampering for security reasons
	strSubFolderName = Replace(strSubFolderName, "../", "", 1, -1, 1)
	strSubFolderName = Replace(strSubFolderName, "..", "", 1, -1, 1)
	strSubFolderName = Replace(strSubFolderName, "./", "", 1, -1, 1)
	strSubFolderName = Replace(strSubFolderName, ".", "", 1, -1, 1)

Only add this to them:
	strSubFolderName = Replace(strSubFolderName, "/", "", 1, -1, 1)
	strSubFolderName = Replace(strSubFolderName, "\", "", 1, -1, 1)
	strSubFolderName = Replace(strSubFolderName, "..", "", 1, -1, 1)
