Description:
An input validation vulnerability was reported in the Eudora WorldMail Server. A remote user can conduct cross-site scripting attacks against e-mail users.
exploitlabs.com reported that a search feature does not filter HTML code from user-supplied input when displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Eudora WorldMail Server software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
A demonstration exploit URL is provided:
http://[host]:8888/c%3dAE?%3FO=%3CSCRIPT%3Ealert%28document.cookie%29%3B%3C%2FSCRIPT%3E
|
Impact:
A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Eudora WorldMail Server software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

VUNERABILITY / EXPLOIT
======================
Vunerable hosts display the following:
-------------- snip ----------------------
A convenient hypertext interface to LDAP and X.500 Directories.
Local domains and aliases
Results for: entries at the top level
Name Description
Countries
AE <---------------- example country
IT
CA
--------------- snip --------------------
Select a country ( "AE" used as example )
you should see something like the following..
http://[host]:8888/c%3dAE
and a search box
"One-level search in AE:"
<FORM METHOD=GET ACTION="/c%3dAE">
<A NAME="search_form">One-level search in</A> <STRONG>AE</STRONG>:<br>
<INPUT NAME="?O" SIZE=39><INPUT TYPE=submit VALUE="Search">
<INPUT TYPE=reset VALUE="Clear"></FORM>
enter sum cool XSS...
<SCRIPT>alert(document.cookie);</SCRIPT>
and get
http://[host]:8888/c%3dAE?%3FO=%3CSCRIPT%3Ealert%28document.cookie%29%3B%3C%2FSCRIPT%3E
the results are rendered by the output of the formatted html.
yes, it just a non persistant XSS, but this is running as a service on
port 8888 and is a mail processing server, so there may be other issues
( DoS ? ) as well.
I belive LDAP has some DCOM connectivity as well, and there could be issies
with the LDAP...
