A lack of input validation in AWStats may allow a remote attacker to execute arbitrary commands.
AWStats is a Perl CGI script that collects and graphically displays statistics from web, FTP, and mail servers. The
configdir parameter, within the awstats.pl Perl script, is supplied user-controlled data and then passed as a parameter to the Perl routine
open(). A lack of input validation on the
configdir parameter may allow an attacker to compromise a vulnerable server. If an attacker supplies this parameter with arbitrary commands prefixed with the '|' character, those commands will be executed on the server.
Please note that according to public reports, this vulnerability is being actively exploited.
If a remote attacker supplies AWStats with specially crafted input, that attacker may be able to execute arbitrary commands with the privileges of the attacked server process, in most cases user
This issue has been corrected in AWStats version 6.3. Users are strongly encouraged to upgrade to this version.
