Account Manager CGI - access admin control panel



Vulnerability

    Account Manager CGI

Affected

    ALL including LITE and PRO haven't been able to test ENTERPRISE

Description

    'n30' found following.  The  Script allows any remote user  access
    to the Administration Control Panel through overwriting the  Admin
    Password with  one of  their own  making.   This is possible since
    the  script  parses  the  inputted  data  with total disregard for
    whether the current userhas Admin priveleges.  Therefore calling

        www.server.com/cgibin/amadmin.pl?setpasswd

    using a POST command would allow the password to be altered.

    Using this exploit would give a remote user access to add and
    remove users from protected areas of your website perphaps to
    other more interesting CGI's.

    Here comes the exploit:
