## Vulnerable Application
`Openfire's` administrative console, a web-based application, was found to be vulnerable to a path traversal attack
via the setup environment using the path `http://localhost:9090/setup/setup-s/%u002e%u002e/%u002e%u002e/`.
Endpoints such as `log.jsp`, `user-groups.jsp` and `user-create.jsp` can be used to gain unauthorized admin access.
It allows an unauthenticated user to use the unauthenticated `Openfire` Setup Environment in an already configured
`Openfire` environment to access restricted pages in the `Openfire Admin Console` reserved for administrative users.
This module will use the vulnerability to create a new admin user that will be used to upload a `Openfire` management plugin
weaponized with a `Java` native payload that triggers an RCE.
The vulnerability affects all versions of `Openfire` that have been released since April 2015, starting with version `3.10.0`.
The problem has been patched in `Openfire` release `4.7.5` and `4.6.8`, and further improvements will be included
in the first version on the `4.8` branch, which is version `4.8.0`.
This module has been tested on:
- [ ] Ubuntu Linux 22.04.
* Openfire 3.10.1, 4.0.4, 4.1.0, 4.2.0, 4.3.0, 4.4.0, 4.5.0, 4.6.0. 4.7.0, 4.7.1, 4.7.3
* Java 7, 8, 17
- [ ] Windows Server 2019 Datacenter
* Openfire 4.7.3
* Java 20
**Instructions for an Openfire installation:**
Download Openfire releases [here](https://github.com/igniterealtime/Openfire/releases?page=1)
Follow installation instructions [here](https://download.igniterealtime.org/openfire/docs/latest/documentation/install-guide.html)
## Verification Steps
- [ ] Start `msfconsole`
- [ ] `exploit/multi/http/openfire_auth_bypass_rce_cve_2023_32315`
- [ ] `set rhosts <ip-target>`
- [ ] `set rport <port>`
- [ ] `set target <0=Java Universal>`
- [ ] `exploit`
- [ ] you should get a `reverse shell` or `Meterpreter` session depending on the `payload` and `target` settings
