Working With NeXpose

From Metasploit Unleashed
Jump to: navigation, search

With the acquisition of Metasploit by Rapid7 back in 2009, there is now excellent compatibility between Metasploit and the NeXpose vulnerability scanner. Rapid7 has a community edition of their scanner that is available at http://www.rapid7.com/vulnerability-scanner.jsp. After we have installed and updated NeXpose, we run a full credentialed scan against our vulnerable Linux machine.

We create a new report in NeXpose and save the scan results in 'NeXpose Simple XML' format that we can later import into Metasploit. Next, we fire up Metasploit, create a new workspace, and use the 'db_import' command to auto-detect and import our scan results file.

We now have NeXpose's report at out disposal directly from the msfconsole. As discussed in a previous modules, using the database backend commands, we can search this information using a few simple key strokes. One that was not covered however was the 'vulns' command. We can issue this command and see what vulnerabilities were found by our NeXpose scan. With no options given 'vulns' will simply display every vulnerability found such as service names, associated ports, CVEs (if any) etc.

Much like the 'hosts' & 'services' commands, we have a few options available to produce a more specific output when searching vulnerabilities stored in our imported report. Let's take a look at those.

msf > vulns -h
Print all vulnerabilities in the database

Usage: vulns [addr range]

  -h,--help             Show this help information
  -p,--port <portspec>  List vulns matching this port spec
  -s <svc names>        List vulns matching these service names
  -S,--search           Search string to filter by
  -i,--info             Display Vuln Info

Examples:
  vulns -p 1-65536          # only vulns with associated services
  vulns -p 1-65536 -s http  # identified as http on any port
  


Lets target a specific service we know to be running on Metasploitable and see what information was collected by our scan. We'll display vulnerabilities found for the 'mysql' service. Using the following options: '-p' to specify the port number, '-s' service name and finally '-i' the vulnerability information.

msf > vulns -p 3306 -s mysql -i
