This site is meant to be used as a tool for users of open source and sometimes commercial software who must keep constant track of new security bugs as soon as they appear in the wild. In its current state it constantly scans a number of security focused mailing lists for posts matching your criteria.
System Administrators who manage web based software are the primary audience for this tool, although it may be useful for anyone who wishes to keep track of 0-day advisories in their own hosted applications.
This tool was primarily written to track 0-day advisories on the BugTraq mailing list for php based web applications that I administer. However as it simply scans any number of different mailing lists based on very flexible criteria there are many other possible uses. At the moment however I would like to keep it security oriented.
My idea was that since many of these exploits consist of XSS, file include or SQL Injection which are generally fairly simple to fix by even a beginning programmer, but may not be fixed by the official provider for some time, it would be useful to have a way to scan bugtraq and other mailing lists and be alerted as soon as these exploits are discovered.
Even given the informal nature of these postings this is quite accurate as the vast majority of posters will put the application/project/component name in the subject of the message.
