*Product Introduction Overview:*  
NetCat.ru is russian local company. "NetCat designed to create an absolute  
majority of the types of sites: from simple "business card" with a minimum  
content to complex web-based systems, from corporate offices to online  
stores, libraries or media data - in other words, projects completely

and markup languages. NetCat constantly improving, adds new features. In  
the process of finalizing necessarily take into account the wishes of our

*(2) Vulnerability Details:*  
NetCat 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 other NetCat products 0-day vulnerabilities have been found by some  
other bug hunter researchers before. NetCat has patched some of them. Gmane  
(pronounced "mane") is an e-mail to news gateway. It allows users to access  
electronic mailing lists as if they were Usenet newsgroups, and also  
through a variety of web interfaces. Gmane is an archive; it never expires  
messages (unless explicitly requested by users). Gmane also supports  
importing list postings made prior to a list's inclusion on the service. It  
has published suggestions, advisories, solutions related to Directory  
Traversal vulnerabilities.
