Subject [jira] [Commented] (COLLECTIONS-580) Arbitrary remote code execution with InvokerTransformer
Date Wed, 18 Nov 2015 14:51:12 GMT


Tiago Stürmer Daitx commented on COLLECTIONS-580:

According to CVE assignment team [1] no CVE ID will be allocated for this issue and:

"The CVE-2015-4852 ID came from Oracle and must remain associated only with Oracle's own software
(WebLogic Server is the product they've named)."

but then Oracle's Thomas Keefe reply [1] to that thread stated:

"We do not have a problem with this use of the CVE# we registered (CVE-2015-4852)."

> 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.
