+## 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`.
+
+### FILEPATH (Required)
+
+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.
+
+
+## Scenarios
+### selenium/standalone-firefox:3.141.59 installed with Docker on Ubuntu 24.04
