When I visit /home.php it redirects to /admin.php Lets capture the request in burp.

302 Found which is redirection, We can stop a redirection using burp.

All we need to do is change 302 Found to 200 Ok For that open Proxy -> Options -> Match and Replace.

Now we can visit /home.php

When checking those tabs this looks Local FIle Inclusion

I checked that in Burp and yeah its a LFI

I tried to read admin.php using LFI Its looks like a password : qMDdyZh3cT6eeAWD for ldap

We can use ldapsearch tool since we got password.

Reference :


-b searchbase	Use searchbase as the starting point for the search instead of the default.

-x     		  	Use simple authentication instead of SASL.

-D binddn 		Use the Distinguished Name binddn to bind to the LDAP directory.  For SASL binds, the server is expected to ignore this value.

-w password 	Use passwd as the password for simple authentication

We got User zeus Password which is base64 encoded.

zeus : cetkKf4wCuHC9FET

I tried login with this in SSH

Privilege Escalation:

Like always I started with sudo -l

We can run dpkg as root without password.

Searched that in GTFOBins

The machine doesn’t have fpm so I created that payload in my machine and uploaded here.
