The goal of this pattern is to discover server software that only applies filters to one version, but not the other. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. With AWStats, you can track website visits, referring websites, search engines, operating systems, browsers, and much more. If you extract the compressed AWStats distribution file, then you can find the script under tools directory. I've installed awstats on my new CentOS 7 webserver and keep getting client denied errors when trying to access it: Text. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. AWStats is a free and open-source log analyzer that provides detailed insights into the traffic of your Apache web server. OK, I'm sure there's a simple solution to this but my brain's fried today. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Databasebreakday mean: summary file will create in daily basis: each day will have it own summary file :. It's mean: each month will have it own summary file :. This attack targets the encoding of the Slash characters. Awstats read log file and create summary text file in monthly basis by default. Using Escaped Slashes in Alternate Encoding.It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. This is often referred as escaped ending or percent-encoding. This depends on the way you setup your web server and cgi directories. It's absolute or relative URL you must enter to run AWStats as a CGI. AWstats works as a CGI or from command line and shows you all possible information your log. Run Webmin, go to the 'AWStats LogFile Analysis' menu. For instance US-ASCII space character would be represented with %20. AWStats is a powerful tool which generates server statistics. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). A URL may contain special character that need special syntax handling in order to be interpreted. An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. This attack targets the encoding of the URL combined with the encoding of the slash characters. AWStats common use is made in 3 steps: The install and setup.
