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. *(2.1) *The first cipher programming flaw occurs at "/section.php" page with "&Module" parameter. *References:* http://www.tetraph.com/security/directory-traversal-vulnerability/724cms-5-01-directory-path-traversal-security-vulnerabilities/ http://securityrelated.blogspot.com/2015/03/724cms-501-directory-path-traversal.html http://www.inzeed.com/kaleidoscope/computer-web-security/724cms-5-01-directory-path-traversal-security-vulnerabilities/ http://diebiyi.com/articles/%E5%AE%89%E5%85%A8/724cms-5-01-directory-path-traversal-security-vulnerabilities/ https://computertechhut.wordpress.com/2015/03/14/724cms-5-01-directory-path-traversal-security-vulnerabilities/ http://marc.info/?a=139222176300014&r=1&w=4 http://en.hackdig.com/wap/?id=17404 -- Wang Jing, Division of Mathematical Sciences (MAS), School of Physical and Mathematical Sciences (SPMS), Nanyang Technological University (NTU), Singapore. http://www.tetraph.com/wangjing/ https://twitter.com/justqdjing
