The article describes a security vulnerability when deserializing Java objects from untrusted sources with the Apache commons-collections library , containing certain risky classes, on the classpath. This reported issue impacts many products in the JBoss Middleware Suite, as they include this library.
-
This issue is being managed through CVE 2015-7501
-
Direct exploitation of this vulnerability requires some means of getting an application to accept an object containing one of the risky classes. The patches linked to in this document address the main vulnerability in the commons-collections library; individual flaws will be addressed in other fixes as they are discovered.
An attacker can use the privileges of the user running JBoss Enterprise Application Platform to execute a command on the system.
The following versions of Red Hat Products are impacted:
- Red Hat JBoss A-MQ 6.x
- Red Hat JBoss BPM Suite (BPMS) 6.x
- Red Hat JBoss BRMS 6.x
- Red Hat JBoss BRMS 5.x
- Red Hat JBoss Data Grid (JDG) 6.x
- Red Hat JBoss Data Virtualization (JDV) 6.x
- Red Hat JBoss Data Virtualization (JDV) 5.x
- Red Hat JBoss Enterprise Application Platform 6.x
- Red Hat JBoss Enterprise Application Platform 5.x
- Red Hat JBoss Enterprise Application Platform 4.3.x

- Red Hat JBoss Operations Network (JBoss ON) 3.x
- Red Hat JBoss Portal 6.x
- Red Hat JBoss SOA Platform (SOA-P) 5.x
- Red Hat JBoss Web Server (JWS) 3.x
- Red Hat OpenShift/xPAAS 3.x
- Red Hat Subscription Asset Manager 1.3
Take Action
The quickest way to resolve this specific deserialization vulnerability is to remove the vulnerable class files (
InvokerTransformer
,
InstantiateFactory
, and
InstantiateTransformer
)in all commons-collections jar files. Any manual changes should be tested to avoid unforseen complications.
If you bundle commons-collection library in your application you may still be vulnerable, even after the forthcoming patches are applied. You'll need to make changes to the commons-collections library yourself if you package one.
