As you can see there is only one port open :
Port 80 - HTTP
Web Enumeration
We get a static login page as below 👇🏻
There is nothing much here , let’s do some directory busting .
ffuf -c -t 100 -w /usr/share/wordlists/dirb/common.txt -u http://git-happens.thm/FUZZ
We get the following directories
.git/HEAD
css
index.html
The .git directory is what interests me since this box is related to git .
Lets take a look at that directory
Cool ! Let’s download all of them using a tool called gitdumper which is a part of GitTools repo.
Link - https://github.com/internetwache/GitTools
Runnning the help command on gitdumper.sh tells us the syntax which we need to use to run the tool .
As the tool says lets create a directory to download all the files. I made a directory called git and ran the script along with the URL of the website.
/opt/tools/GitTools/Dumper/gitdumper.sh http://git-happens.thm/.git/ git

Initial commit
(END)
If you go through the comments of all the commits , one of the comments seem quite interesting .
Seems like its the source code of the login page we saw earlier !
Lets view what changes were made during that commit -
git show 395e087334d613d5e423cdf8f7be27196a360459
After scrolling through the source code, we find this piece of code where there is an insecure login function which contains the username & password of admin 😂
Grab the Super Secret Password 🚩 and submit it ! Yes it’s the flag which you want ✔
