Jolokia Exploitation Toolkit (JET) helps exploitation of exposed jolokia endpoints.

jolokia

Core concept

Jolokia is a protocol bridge that enables users to interact with MBeans (JMB) through HTTP. This endpoint "exposed JMX features" which are often dangerous, this implies that /jolokia should never be exposed, and if used internally (loopback), should be protected by an authentication mechanism.

Doc says... :)

Jolokia is a JMX-HTTP bridge giving an alternative to JSR-160 connectors. It is an agent based approach with support for many platforms. In addition to basic JMX operations it enhances JMX remoting with unique features like bulk requests and fine grained security policies.

Where to find jolokia

Java projects
/jolokia
/actuator/jolokia
???

Test setup

You can either startup a tomcat server (docker || docker-compose) and install the jolokia war,
Or run docker run --rm -it --net=host bodsch/docker-jolokia and go with the flow ~

Setup & Usage

# Setup with virtualenv
virtualenv -p python3 .venv && source .venv/bin/activate
pip install -r requirements.txt

# Use jolokia-parser.py with remote url
python jolokia-parser.py http://127.0.0.1/jolokia | tee jolokia-parsed.lst

# Or use jolokia-parser.py with local json
curl http://127.0.0.1/jolokia/list -o jolokia-list.json
python jolokia-parser.py jolokia-list.json | sed 's#^/jolokia#http://127.0.0.1/jolokia#g' | tee jolokia-parsed.lst

# Quickly find the cool MBeans
grep -iP 'compilerDirectivesAdd|name=AccessLogValve,type=Valve/pattern|createStandardHost|jfrStart|vmLog|read/Users:database=UserDatabase|MBeanFactory|reloadByURL|jvmtiAgentLoad|environmentManager' jolokia-parsed.lst
# Quickly find information leaks, paths, user, etc
grep -iP 'Runtime/(BootClassPath|ClassPath|InputArguments|LibraryPath|SystemProperties)' jolokia-parsed.lst

The expected output in jolokia-parsed.lst is the following:
