AWStats fails to validate input supplied to pluginmode parameter

Vulnerability Note VU#259785

Original Release Date: 2005-02-25 | Last Revised: 2005-02-25


AWStats performs inadequate validation on user-controlled data that is supplied to the pluginmode parameter. Exploitation of this vulnerability 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. AWStats provides the ability to extend its functionality via plug-ins. Inadequate validation on input supplied to the pluginmode parameter may allow an attacker to execute PERL commands (i.e. the system() function), which can be used to execute arbitrary operating system or shell commands with the privileges of the web server process.


A remote, unauthenticated attacker may be able to execute arbitrary commands or cause a denial-of-service condition.



According to public reports, this vulnerability was corrected in AWStats version 6.4. While this version is available to the public, it is still considered under development (beta). Users are encouraged to consult the AWStats Download page for more information.
