+## Vulnerable Application
+
+This module was successfully tested on:
+
+    * gitlab-ce (v17.2.2-ce.0) installed with Docker on Kali Linux 6.6.15
+
+### Description
+
+This module is a brute-force login scanner that attempts to authenticate to the GitLab with username and password combinations.
+
+## Installation (latest version of gitlab-ce at the time of this writing)
+
+1. `docker pull gitlab/gitlab-ce:17.2.2-ce.0`
+2. `sudo mkdir -p /srv/gitlab/config /srv/gitlab/logs /srv/gitlab/data`
+3. Run the GitLab.
+```
+docker run --detach \                                              
+--hostname localhost \
+--publish 443:443 --publish 80:80 --publish 22:22 \
+--name gitlab \
+--restart always \
+--volume /srv/gitlab/config:/etc/gitlab \
+--volume /srv/gitlab/logs:/var/log/gitlab \
+--volume /srv/gitlab/data:/var/opt/gitlab \
+gitlab/gitlab-ce:17.2.2-ce.0
+```
+4. (Get initial password)
+   `docker exec gitlab cat etc/gitlab/initial_root_password | grep Password:`
+
+## Verification Steps
+
+1. Install GitLab and start it
+2. Start `msfconsole`
+3. Do: `use auxiliary/scanner/http/gitlab_login`
+4. Do: `set rhosts`
+5. Do: set usernames and passwords via the `username` and `password` options, or pass a list via `user_file` and `pass_file` options
+5. Do: `run`
+6. You will hopefully see something similar to:
+
+```
+[+] 192.168.56.6:80 - Login Successful: root:strongpasswordcannotguess
+```
