Title: Red Hat JBoss EAP deserialization of untrusted data
|
|
Application: JBoss EAP 5.2.X and prior versions
|
|
Description: The application server deserializes untrusted data via the
|
|
JMX Invoker Servlet. This can lead to a DoS via resource
|
|
exhaustion and potentially remote code execution.
|
|

|
|
Vendor Status: Will not fix
|
|
CVE Candidate: The Common Vulnerabilities and Exposures project has assigned
|
|
the name CVE-2016-7065 to this issue.
|
|

|
|
|
|
1. Abstract.
|
|
|
|
JBoss EAP's JMX Invoker Servlet is exposed by default on port 8080/TCP. The
|
|
communication employs serialized Java objects, encapsulated in HTTP
|
|
requests and responses.
|
|
|
|
The server deserializes these objects without checking the object type. This
|
|
behavior can be exploited to cause a denial of service and potentially
|
|
execute arbitrary code.
|
|
|
|
The objects that can cause the DoS are based on known disclosed payloads
|
|
taken from:
|
|
|
|
- https://gist.github.com/coekie/a27cc406fc9f3dc7a70d
|
|
|
|
Currently there is no known chain that allows code execution on JBoss EAP,
|
|
however new chains are discovered every day.
|
|
|
|
2. Example Attack Session.
|
|
|
|
Submit an authenticated POST request to the JMX Invoker Servlet URL (for
|
|
example: http://localhost:8080/invoker/JMXInvokerServlet) with one of the
|
|
following objects in the body of the request:
|
|
|
|
* 01_BigString_limited.ser: it's a string object; the server will
|
|
reply in a normal way (object size similar to the next one).
|
|
* 02_SerialDOS_limited.ser: the application server will require
|
|
about 2 minutes to execute the request with 100% CPU usage.
|
|
* 03_BigString.ser: it's a string object; the server will
|
|
reply in a normal way (object size similar to the next one).
|
|
* 04_SerialDOS.ser: the application server will require an
|
|
unknown amount of time to execute the request with 100% CPU usage.
|
|
|
|
3. Affected Platforms.
|
|
|
|
This vulnerability affects versions 4 and 5 of JBoss EAP.
|
|
|
|
4. Fix.
|
|
|
|
Red Hat will not fix the issue because JBoss EAP 4 is out of maintenance
|
|
support and JBoss EAP 5 is close to the end of its maintenance period.
|
|
|
|
5. Proof Of Concept.

|
|
