- Vulnerability:  
####################  
Input passed to the FolderName parameter in "RTE_file_browser.asp" and   
"file_browser.asp" are 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.
