Vulnerability Exploited:

SQLi Authentication bypass

Privilege Escalation:

Misconfigured cronjob

Exploiting the host:


SSL certificate gives us a new domain so update hosts file:

Visiting the site gives us a login page.

Capture a login with burp and send it to the intruder to be fuzzed for sqli

Can bypass the login with an sqli payload:

Request this payload in the browser and we are logged in

Under the tools tab you can generate a VPN config file so test it for command execution.

Eventually we found it is vulnerable using the following command:

Successfully hitting our server:

Generate a php reverse shell with msfvenom and host it in the webroot

Generate a reverse shell with nc and URL encode it.

Shell spawned on 443

Another misconfigured cronjob

Inspecting the file shows us that it is executing another sh file located in /var/www/cmd/

So create the file and wait for it to execute

Now we have a root shell and collect our flags
