Vendor description:
|
||
-------------------
|
||
"WSO2 Carbon redefines middleware by providing an integrated and componentized
|
||
middleware platform that adapts to the specific needs of any enterprise
|
||
IT project - on premise or in the cloud.
|
||
100% open source and standards-based, WSO2 Carbon enables developers to rapidly
|
||
orchestrate business processes, compose applications and develop services using
|
||
WSO2 Developer Studio and a broad range of business and technical services that
|
||
integrate with legacy, packaged and SaaS applications.
|
||
The lean, complete, OSGi-based platform includes more than 175 components – OSGi
|
||
bundles or Carbon features. The WSO2 Carbon core framework functions as
|
||
“Eclipse for servers” and includes common capabilities shared by all WSO2
|
||
products, such as built-in registry, user management, transports, security,
|
||
logging, clustering, caching and throttling services, co-ordination, and a
|
||
GUI framework."

|
||
|
||
"The WSO2 Dashboard Server (formerly WSO2 User Engagement Server) helps to
|
||
rapidly create visually appealing and engaging web components such as
|
||
dashboards, and gadgets, and unlocking data for business intelligence and
|
||
monitoring. With the host of capabilities that Dashboard Server provides
|
||
out-of-the-box, going from data to screen has never been easier."

||
Business recommendation:
|
||
------------------------
|
||
SEC Consult recommends to perform a thorough security review conducted by
|
||
security professionals to identify and resolve all security issues.
|
||
|
||
|
||
Vulnerability overview/description:
|
||
-----------------------------------
|
||
1) Stored Cross-Site Scripting in WSO2 Dashboard (CVE-2018-8716)
|
||
The dashboard is used by the end-users to manage their accounts, change passwords,
|
||
alter their profiles, or change certain settings. An attacker is able to inject
|
||
arbitrary JavaScript payloads into various textboxes (username, home address,
|
||
lastname, firstname, etc).
|
||
|
||
The payloads are permanently stored in the dashboard and triggered every time the
|
||
dashboard is visited. The payload is also potentially triggered in the carbon
|
||
part of WSO2, which means that an attacker would be able to inject payloads
|
||
from the front-end application into a middleware application, which is not
|
||
accessible from the internet and attack administrators.
|
||
|
||
2) Stored Cross-Site Scripting in WSO2 Carbon
|
||
The carbon UI offers a feature to add multiple BPS-Worker Hosts. In the worker
|
||
host URL an arbitrary JavaScript payload can be injected and permanently stored
|
||
in the web application.
|
||
|
||
|
||
Proof of concept:
|
||
-----------------
|
||
1) Stored Cross-Site Scripting in WS02 Dashboard
|
||
The following input fields are vulnerable and JavaScript payloads can be directly
|
||
injected:
|
||
- Firstname
|
||
- Lastname
|
||
- Username
|
||
- Address
|
||
|
||
It is suspected, that all user inputs are returned unfiltered in all server responses.
|
||
|
||
2) Stored Cross-Site Scripting in WSO2 Carbon
|
||
To demonstrate the vulnerability, it is sufficient to add a new BPS worker and set
|
||
the URL to the following payload: "><img src=x onerror=aler(document.cookie)>
|
||
|
||
Everytime the carbon middleware application is accessed, the payload is triggered.
|
||
|
||
|
||
Vulnerable / tested versions:
|
||
-----------------------------
|
||
The following version has been tested which was the most recent version
|
||
at the time of discovery:
|
||
|
||
* WSO2IS 5.3.0
|
||
|
||
|
||
Vendor contact timeline:
|
||
------------------------
|
||
2018-01-25: Contacting vendor through security@wso2.com
|
||
2018-02-08: Asking for status update. Vendor responds, that they are
|
||
still investigating the issue.
|
||
2018-02-21: Vendor responds with release date and further details
|
||
concerning the nature of the vulnerabilities. The XSS in the
|
||
Carbon component was a duplicate and should be already fixed.
|
||
Concerning the XSS in the dashboard a fix is implemented
|
||
and will be rolled out with the release of WSO2 Identity
|
||
Server 5.5.0.
|
||
2018-03-14: Requesting CVE from Mitre for the stored XSS in the Dashboard.
|
||
2018-03-15: Mitre assigned CVE-2018-8716.
|
||
2018-03-26: Vendor informed us, that the final release of the updated
|
||
software will be on 5th of April.

||
|
||
Solution:
|
||
---------
