Webmin miniserv.pl username Parameter Format String Vulnerability

Vulnerability Assessment Summary
Checks for username parameter format string vulnerability in Webmin miniserv.pl

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server is affected by a format string vulnerability.

Description :

The remote host is running Webmin or Usermin, web-based interfaces for
Unix / Linux system administrators and end-users.

Webmin and Usermin both come with the Perl script 'miniserv.pl' to
provide basic web services, and the version of 'miniserv.pl' installed
on the remote host contains a format string flaw when logging failed
authentication attempts. Using specially-crafted values for the
'username' parameter of the 'session_login.cgi', a possible hacker may be
able to exploit this flaw to crash the affected server or potentially
to execute arbitrary code on the affected host under the rights of
the userid under which 'miniserv.pl' runs, by default root.
