Consider upping with --ulimit. May cause harm to sensitive servers [!] Your file limit is very small, which negatively impacts RustScan's speed.

Running gobuster on the port 8000 But we did see an entry in `robots.txt` Logging in with `admin:admin` Here we can see these are html pages but we can include php code in between it And we have a RCE working so let's leverege this to get a reverse shell From the looks of it this a base64 ecoded text Doing a `cat /etc/crontab` to list system wide crontab we see a cronjob running as root We also see `secret.txt` in `/var/www/html/topSecretPrivescMethod` Reading `/var/lib/rary` from the hints This was the flag that we need to enter in the correct format ### PORT 8001 (HTTP) ### PORT 80002 (HTTP) To get a reverse shell paste the php reverse shell without having `php` tags in it Now we can edit that script which is running in crontab To get `root.txt`
