Exploit target: [*] Started reverse handler on 192.168.127.159:8888 The following command line will scan all TCP ports on the Metasploitable 2 instance: Nearly every one of these listening services provides a remote entry point into the system. For example, noting that the version of PHP disclosed in the screenshot is version 5.2.4, it may be possible that the system is vulnerable to CVE-2012-1823 and CVE-2012-2311 which affected PHP before 5.3.12 and 5.4.x before 5.4.2. So, lets set it up: mkdir /metafs # this will be the mount point, mount -t nfs 192.168.127.154:/ /metafs -o nolock # mount the remote shared directory as nfs and disable file locking.

RHOST 192.168.127.154 yes The target address Step 1: Setup DVWA for SQL Injection. Inspired by DVWA, Mutillidae allows the user to change the "Security Level" from 0 (completely insecure) to 5 (secure). The VNC service provides remote desktop access using the password password. It gives you everything you need from scanners to third-party integrations that you will need throughout an entire penetration testing lifecycle. This VM could be used to perform security training, evaluate security methods, and practice standard techniques for penetration testing.
