## Vulnerable Application
|
|
|
|
If there is an open selenium web driver, a remote attacker can send requests to the victims browser.
|
|
In certain cases this can be used to access to the remote file system.
|
|
|
|
The vulnerability affects:
|
|
|
|
* all version of open Selenium Server (Grid)
|
|
|
|
This module was successfully tested on:
|
|
|
|
* selenium/standalone-firefox:3.141.59 installed with Docker on Ubuntu 24.04
|
|
* selenium/standalone-firefox:4.0.0-alpha-6-20200730 installed with Docker on Ubuntu 24.04
|
|
* selenium/standalone-firefox:4.6 installed with Docker on Ubuntu 24.04
|
|
* selenium/standalone-firefox:4.27.0 installed with Docker on Ubuntu 24.04
|
|
* selenium/standalone-chrome:4.27.0 installed with Docker on Ubuntu 24.04
|
|
* selenium/standalone-edge:4.27.0 installed with Docker on Ubuntu 24.04
|

|
|
|
### Installation
|
|
|
|
1. `docker pull selenium/standalone-firefox:3.141.59`
|
|
|
|
2. `docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-firefox:3.141.59`
|
|
|
|
|
|
## Verification Steps
|
|
|
|
1. Install the application
|
|
2. Start msfconsole
|
|
3. Do: `use auxiliary/gather/selenium_file_read`
|
|
4. Do: `run rhost=<rhost>`
|
|
5. You should get a file content
|
|
|
|
|
|
## Options
|
|
|
|
### SCHEME (Required)
|
|
|
|
This is the scheme to use. Default is `file`.
|

This is the file to read. Default is `/etc/passwd`.
|
|
|
|
### BROWSER (Required)
|
|
|
|
This is the browser to use. Default is `firefox`.
|
|
|
|
### TIMEOUT (required)
|
|
|
|
This is the amount of time (in seconds) that the module will wait for the payload to be
|
|
executed. Defaults to 75 seconds.
|
|
|
|
|
