Subject [jira] [Commented] (COLLECTIONS-580) Arbitrary remote code execution with InvokerTransformer
Date Thu, 19 Nov 2015 10:59:12 GMT

Stevie Beck commented on COLLECTIONS-580:
-----------------------------------------

This reminds me of the the general "SerialDoS" code, published here: https://gist.github.com/coekie/a27cc406fc9f3dc7a70d
I am not THAT Java expert, so I just assume, that any application that allows deserialization
from untrusted input, can be DoS'ed - regardless what libraries are included in the classpath.
Just creation of code execution needs more investigation and creativity and the need to find
suitable gadgets...

> With {{InvokerTransformer}} serializable collections can be build that execute arbitrary
Java code. {{sun.reflect.annotation.AnnotationInvocationHandler#readObject}} invokes {{#entrySet}}
and {{#get}} on a deserialized collection. If you have an endpoint that accepts serialized
Java objects (JMX, RMI, remote EJB, ...) you can combine the two to create arbitrary remote
code execution vulnerability.
> I don't know of a good fix short of removing {{InvokerTransformer}} or making it not
Serializable. Both probably break existing applications.
> This is not my research, but has been discovered by other people.
