- Description:
|
|
####################
|
|
Web Wiz Rich Text Editor (RTE) is a free WYSIWYG HTML Rich Text Editor that replaces standard textarea's with an advanced Word style HTMLarea.
|
|
|
|
####################
|
|
- 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.
|
|
Moreover, by using "RTE_popup_save_file.asp" attacker can make his/her HTML or HTM file on the server, so this can be used in XSS attacks or making fake pages.
|
|
|
|
-POC:
|
|
http://[WebWiz RTE]/RTE_file_browser.asp?look=save&sub=\.....\\\.....\\\.....\\\.....\\\.....\\\
|
|
http://[WebWiz RTE]/RTE_popup_save_file.asp
|

|
- Fast Solution :
|
|
####################
|
|
1- 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)
|
|
2- Rename "RTE_popup_save_file.asp" till main solution by vendor
