## What it is
JexBoss is a Python command-line tool for testing and exploiting JBoss Application Server and Java deserialization vulnerabilities. It supports multiple exploitation vectors such as jmx-console, web-console invokers, and RMI over HTTP across JBoss versions 3-6.

## Use cases
- test jboss server for known vulnerabilities
- exploit java deserialization vulnerabilities
- verify jmx-console exposure on a jboss server
- get a reverse shell from a vulnerable java application
- scan a host for jboss admin-console and invoker endpoints
- check jenkins CLI RCE and remote JMX CVEs

## When to choose
- you are doing authorized penetration testing against JBoss or legacy Java applications
- you need a ready-made exploit tool for Java deserialization gadget chains
- you want to verify whether a JBoss instance is vulnerable before remediation

## When to avoid
- you need a general-purpose vulnerability scanner rather than targeted JBoss/Java exploits
- your environment requires Python 3 only, since the tool targets Python 2.7
- you want actively maintained tooling - the last release was in 2020
