There is a website on port 80:

There is a website on port 3000:

There is a repo with a script: Checking commits: We get the access token

Now we can list repositories:

curl -H "Authorization: token 43ce39bb0bd6bc489284f2905f033ca467a6362f" "http://10.10.108.22:3000/api/v1/user/repos" | jq

We get a private repository

Now since we have the access token we might be able to clone it

Using username as ellen.freeman and password as the token:

Now we have access to the website repository Reading the readme.md:

Any changes we make will be deploy: Now uploading a webshell

git add shell.aspx
git commit -am "Shell added
git push

Now we can access the webshell:

Now getting a reverse shell and checking documents folder we find config.xml for mremoteNG Now we can decode the password:

Using mremoteng_decrypt:

Now on desktop: We have PDF24 toolbox

And checking hidden folder _install on c drive we find the msi file:

Then following the privesc from https://sec-consult.com/vulnerability-lab/advisory/local-privilege-escalation-via-msi-installer-in-pdf24-creator-geek-software-gmbh/ We get a system shell.
