*Product Introduction Overview:*  
"724CMS is a content management system (CMS) that has customers spread in  
Canada, Japan, Korean, the United States, European and many others. It  
allows publishing, editing and modifying content, organizing, deleting as  
well as maintenance from a central interface. Meanwhile, 724CMS provides  
procedures to manage workflow in a collaborative environment."  
  
"A CMS helps you create and store content in a shared repository. It then  
manages the relationships between content items for you (e.g. keeping track  
of where they fit into the site hierarchy). Finally, it ensures that each  
content item is connected to the right style sheet when it comes to be  
published. Some CMSs also provide facilities to track the status of content  
items through editorial processes and workflows."  
  
  
  
  
  
  
*(2) Vulnerability Details:*  
724CMS web application has a security bug problem. It can be exploited by  
Directory Traversal - Local File Include (LFI) attacks. A local file  
inclusion (LFI) flaw is due to the script not properly sanitizing user  
input, specifically path traversal style attacks (e.g. '../../') supplied  
to the parameters. With a specially crafted request, a remote attacker can  
include arbitrary files from the targeted host or from a remote host . This  
may allow disclosing file contents or executing files like PHP scripts.  
Such attacks are limited due to the script only calling files already on  
the target host.  
  
Several 724CMS products vulnerabilities have been found by some other bug  
hunter researchers before. 724CMS has patched some of them. The MITRE  
Corporation is a not-for-profit company that operates multiple federally  
funded research and development centers (FFRDCs), which provide innovative,  
practical solutions for some of our nation's most critical challenges in  
defense and intelligence, aviation, civil systems, homeland security, the  
judiciary, healthcare, and cybersecurity. It has published suggestions,  
advisories, solutions details related to 724CMS vulnerabilities.
