+## PORT 80 (HTTP)
+
+
+From the nmap scan we see 3 disallowed entries
+
+
+
+The first entry which is `/api/` gives 503 which we get when a server is currently unable to handle the request due to a temporary overloading or maintenance of the server.
+
+
+
+The second entry invloves uploading a image file
+
+
+
+And for the third I didn't know how to access `/\*.bak.txt$`
+
+
+
+## Dirsearch
+
+For fuzzing I used dirsearch but I was getting a lot of 503 status codes
+
+
+
+But I did saw `/api/` which was having 301 status code with a length of `169` bytes
+
+
+
+I also ran `nikto` and it found some cert and archive files but they were also giving 503 errors
+
+
+
+So there is some WAF (Web Application Firewall) that is implemented that we need to bypass so here automated tools may not work .
+
+For the web flag I looked at the hint which said about a "well-known file", I though about robots.txt , the javascript file but it was a dead end so started to guess it and eventually got there
+
+
+
+It says to make a request with a HEAD
+
+
+
+Going back to `robots.txt` I tried to combine two disallowed entries and got to somewhere
+
+
+
+
+
+If we focus on this part
+
+
+
+We can see that it's pointing at `/exif` and has a parameter `url`
+
+
+
+
+
+We can do LFI now , since it's a docker container you can tell as there aren't any usernames so we'll directly go `/root/` directory
+
+
+
+Reading the `dev-note.txt`
+
+
+
+So we got the password but not sure if it's for hydra. Visiting the `/root/.git/` folder
+
+
+
+
+I used this command to search for files
+
+```
+http://10.10.176.126/api/exif?url=http://api-dev-backup:8080/exif?url=;cd%20/root/.git/;pwd;ls%20-la%20objects
+```
+
+
+
+And found objects which could be recovered using `git show
