Blog post "commons" vulnerability
Hello Sally, currently there is a security vulnerability doing the rounds which uses as an example Apache Commons Collection. It is not really a bug in Commons Collection, but there is a lot of fuzz. So since we are doing somethign in the Apache Commons team against the problem we wanted to make a public statement. Here is a blog post, which was discussed on the developer mailinglist. What is needed to get it published via ASF blogs? (i.e. do you need a PMC vote or similiar?) The syntax for links is markdown, you might have to replace them (so the links are hidden). Let me know if you have some suggestions for improvement. Greetings Bernd (e...@apache.org) --- Apache Commons statement to widespread Java object de-serialisation vulnerability Authors: Bernd Eckenfels, Gary Grogory for Apache Commons In their [talk](http://frohoff.github.io/appseccali-marshalling-pickles/) "Marshalling Pickles - how deserializing objects will ruin your day" at AppSecCali2015 Gabriel Lawrence ([@gebl](https://twitter.com/gebl)) and Chris Frohoff ([@frohoff](https://twitter.com/frohoff)) presented various security problems when applications accept serialized objects from untrusted source. A major finding describes a way to execute arbitrary Java functions and even inject manipulated bytecode when using Java Object Serialization (as used in some remote communication and persistence protocols). Build on Frohoff's tool [ysoserial](https://github.com/frohoff/ysoserial), Stephen Breen ([@breenmachine](https://twitter.com/breenmachine)) of Foxglove Security inspected various products like WebSphere, JBoss, Jenkins, WebLogic, and OpenNMS and describes (http://foxglovesecurity.com/2015/11/06/what-do-weblogic-websphere-jboss-jenkins-opennms-and-your-application-have-in-common-this-vulnerability/) for each of them various attack scenarios. Both research works shows that developers put too much trust in Java Object Serialization. Some even de-serialize objects pre-authentication. When deserializing an Object in Java you typically cast it to an expected type, and therefore Java's strict type system will ensure you only get valid object trees. Unfortunately, by the time the type checking happens, platform code has already created and executed significant logic. So, before the final type is checked a lot of code is executed from the readObject() methods of various objects, all of which is out of the developer's control. By combining the readObject() methods of various classes which are available on the classpath of the vulnerable application an attacker can execute functions (including calling Runtime.exec() to execute local OS commands). The best protection against this, is to avoid using a complex serialization protocol with untrusted peers. It is possible to limit the impact when using a custom ObjectInputStream which overwrites [resolveClass()](http://docs.oracle.com/javase/7/docs/api/java/io/ObjectInputStream.html#resolveClass%28java.io.ObjectStreamClass%29) to implement a whitelist approach. This might however not always be possible, when a framework or application server provides the endpoint. This is rather bad news, as there is no easy fix and applications need to revisit their client-server protocols and overall architecture. In these rather unfortunate situations, people have looked at the sample exploits. Frohoff provided "gadget chains" in sample payloads which combine classes from Groovy runtime, Sprint framework or Apache Commons Collection. It is quite certain that you can combine more classes to exploit this weakness, but those are the chains readily available to attackers today. https://twitter.com/gebl/status/662786601425080320> Even when the classes implementing a certain functionality cannot be blamed for this vulnerability, and fixing the known cases will also not make the usage of serialization in an untrusted context safe, there is still demand to fix at least the known cases, even when this will only start a Whack-a-Mole game. In fact, it is for this reason the original team did not think it is necessary to alert the Apache Commons team, hence work has begun relatively late. The Apache Commons team is using the ticket [COLLECTION-580](https://issues.apache.org/jira/browse/COLLECTIONS-580) (http://svn.apache.org/viewvc/commons/proper/collections/branches/COLLECTIONS_3_2_X/src/java/org/apache/commons/collections/functors/InvokerTransformer.java?r1=1713136&r2=1713307&pathrev=1713307&diff_format=h) to address the issue in the 3.2 and 4.0 branches of commons-collection by disabling de-serialization of the class InvokerTransformer. A to-do item being discussed is whether to provide programmatic enabling of the feature on a per-transformer basis. There is some precendence for this, the class com.sun.org.apache.xalan.internal.xsltc.trax.TemplatesImpl which is part of Oracle and OpenJDK JREs and which allows to inject and run bytecode, does reject deserialization if a security manager is defined.

Re: Blog post "commons" vulnerability
I think the post is nicely written and I don't personally object to anything in it. I have not dug into the details of the subject though. I wonder, also, if the "statement from Commons" bit is necessary. We have never done this before and we are in general pretty conservative at the ASF level in making public statements qua ASF or qua Apache Foo. Why wouldn't a post syndicated via PlanetApache as Gary or Bernd do? Phil On 11/9/15 9:06 AM, Sally Khudairi wrote: > Thanks, Bernd.

On the whole this looks good to me... there are a few grammatical errors though. Not being familiar with your process will there be a quick scrub at the end to find all these or do you need me to point them out?

Thanks, Chris. I'll include your edits. Status-wise, I'm uploading the copy to blogs.apache.org.

Both research works show[s] that developers put too much trust in Java ( remove plural) Object Serialization. Some even de-serialize objects pre-authentication. When deserializing an Object in Java you typically cast it to an expected type, and therefore Java's strict type system will ensure you only get valid object trees. Unfortunately, by the time the type checking happens, platform code has already created and executed significant logic. So, before the final type is checked, a lot of code is executed from the readObject() methods of various objects, all of which is out of the developer's control. By combining the readObject() methods of various classes which are available on the classpath of the vulnerable application an attacker can execute functions (including calling Runtime.exec() to execute local OS commands). The best protection against this, is to avoid using a complex serialization protocol with untrusted peers. It is possible to limit the impact when using a custom ObjectInputStream which overrides (*** replace “overwrites” with “overrides”) [resolveClass()](http://docs.oracle.com/javase/7/docs/api/java/io/ObjectInputStream.html#resolveClass%28java.io.ObjectStreamClass%29) to implement a whitelist approach ( link to http://www.ibm.com/developerworks/library/se-lookahead/?). This might, however, not always be possible, such as when a framework or application server provides the endpoint. ( add “such as”) This is rather bad news, as there is no easy fix and applications need to revisit their client-server protocols and overall architecture. In these rather unfortunate situations, people have looked at the sample exploits.

Re: Blog post "commons" vulnerability
Hi, I think it is appropriate to sign the post with "Bernd Eckenfels and Gary Gregory, on behalf of the Apache Commons PMC" The content has been open for discussion long enough for anybody to raise concerns. Several PMC members have been involved in this issue. Thank you for helping, Sally!

Re: Blog post "commons" vulnerability
I think that two important actions are missing: - Cut new releases. - Create a CVE id. (No idea, who can do that or how its done.) We should wait with any publication until these are completed.

You only need a CVE ID if there is a vulnerability. I would argue (and the OPs appear to agree with me) that this is NOT a vulnerability in Apache Commons Collections. The vulnerability lies in applications that are blindly deserializing data from an untrusted source. Given the nature of Java deserialization, that is somewhere on the scale between foolish and reckless. Commons is taking action to reduce the risk to developers if they do deserialize untrusted data but that doesn't change the fact that the root cause / vulnerability is the deserialization of untrusted data, not what Commons Collections then does with it.

I won't argue on that. Fact is, there are such applications out there (as of yet, we are aware of Jenkings, OpenNMS, WebSphere, JBoss, and WebLogic [1], but the list is most likely incomplete, and there are unidentified applications), and there is a vulnerability.Hence the need for an identifier.
