Project description

nessus file reader

nessus file reader by LimberDuck (pronounced ˈlɪm.bɚ dʌk) is a CLI tool and python module created to quickly parse nessus files containing the results of scans performed by using Nessus by (C) Tenable, Inc. This module will let you get data through functions grouped into categories like file, scan, host and plugin to get specific information from the provided nessus scan files.

Main features

  • read data from nessus files containing results of scans performed by using Nessus by (C) Tenable, Inc.
  • use it in CLI or as python module

Check code examples.

Installation

Note: It's advisable to use python virtual environment for below instructions. Read more about python virtual environment in The Hitchhiker’s Guide to Python!

Read about virtualenvwrapper in The Hitchhiker’s Guide to Python!: virtualenvwrapper provides a set of commands which makes working with virtual environments much more pleasant.

Install nessus file reader

pip install nessus-file-reader

To upgrade to newer version run:

pip install -U nessus-file-reader

Use

Use in CLI

  1. Run nessus file reader

    nfr

  2. Check help for commands

    nfr [command] --help e.g. nfr file --help

Use as python module

  1. Import nessus-file-reader module.
import nessus_file_reader as nfr
  1. Use file functions to get details about provided file e.g. root, file name, file size.
import nessus_file_reader as nfr

nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)
file_name = nfr.file.nessus_scan_file_name_with_path(nessus_scan_file)
file_size = nfr.file.nessus_scan_file_size_human(nessus_scan_file)
print(f'File name: {file_name}')
print(f'File size: {file_size}')
  1. Use scan functions to get details about provided scan e.g. report name, number of target/scanned/credentialed hosts, scan time start/end/elapsed and more.
import nessus_file_reader as nfr
nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)

report_name = nfr.scan.report_name(root)
number_of_target_hosts = nfr.scan.number_of_target_hosts(root)
number_of_scanned_hosts = nfr.scan.number_of_scanned_hosts(root)
number_of_scanned_hosts_with_credentialed_checks_yes = nfr.scan.number_of_scanned_hosts_with_credentialed_checks_yes(root)
scan_time_start = nfr.scan.scan_time_start(root)
scan_time_end = nfr.scan.scan_time_end(root)
scan_time_elapsed = nfr.scan.scan_time_elapsed(root)
print(f' Report name: {report_name}')
print(f' Number of target/scanned/credentialed hosts: {number_of_target_hosts}/{number_of_scanned_hosts}/{number_of_scanned_hosts_with_credentialed_checks_yes}')
print(f' Scan time START - END (ELAPSED): {scan_time_start} - {scan_time_end} ({scan_time_elapsed})')
  1. Use host functions to get details about hosts from provided scan e.g. report hosts names, operating system, hosts scan time start/end/elapsed, number of Critical/High/Medium/Low/None findings and more.
import nessus_file_reader as nfr
nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)

for report_host in nfr.scan.report_hosts(root):
   report_host_name = nfr.host.report_host_name(report_host)
   report_host_os = nfr.host.detected_os(report_host)
   report_host_scan_time_start = nfr.host.host_time_start(report_host)
   report_host_scan_time_end = nfr.host.host_time_end(report_host)
   report_host_scan_time_elapsed = nfr.host.host_time_elapsed(report_host)
   report_host_critical = nfr.host.number_of_plugins_per_risk_factor(report_host, 'Critical')
   report_host_high = nfr.host.number_of_plugins_per_risk_factor(report_host, 'High')
   report_host_medium = nfr.host.number_of_plugins_per_risk_factor(report_host, 'Medium')
   report_host_low = nfr.host.number_of_plugins_per_risk_factor(report_host, 'Low')
   report_host_none = nfr.host.number_of_plugins_per_risk_factor(report_host, 'None')
   print(f'  Report host name: {report_host_name}')
   print(f'  Report host OS: {report_host_os}')
   print(f'  Host scan time START - END (ELAPSED): {report_host_scan_time_start} - {report_host_scan_time_end} ({report_host_scan_time_elapsed})')
   print(f'  Critical/High/Medium/Low/None findings: {report_host_critical}/{report_host_high}/{report_host_medium}/{report_host_low}/{report_host_none}')
  1. Use plugin functions to get details about plugins reported in provided scan e.g. plugins ID, plugins risk factor, plugins name.
import nessus_file_reader as nfr
nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)

for report_host in nfr.scan.report_hosts(root):
   report_items_per_host = nfr.host.report_items(report_host)
   for report_item in report_items_per_host:
      plugin_id = int(nfr.plugin.report_item_value(report_item, 'pluginID'))
      risk_factor = nfr.plugin.report_item_value(report_item, 'risk_factor')
      plugin_name = nfr.plugin.report_item_value(report_item, 'pluginName')
      print('\t', plugin_id, '  \t\t\t', risk_factor, '  \t\t\t', plugin_name)
  1. If you want to get output for interesting you plugin e.g. "Nessus Scan Information" use below function
import nessus_file_reader as nfr
nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)

for report_host in nfr.scan.report_hosts(root):
   pido_19506 = nfr.plugin.plugin_output(root, report_host, '19506')
   print(f'Nessus Scan Information Plugin Output:\n{pido_19506}')
  1. If you know that interesting you plugin occurs more than ones for particular host e.g. "Netstat Portscanner (SSH)" use below function
import nessus_file_reader as nfr
nessus_scan_file = './your_nessus_file.nessus'
root = nfr.file.nessus_scan_file_root_element(nessus_scan_file)

for report_host in nfr.scan.report_hosts(root):
   pidos_14272 = nfr.plugin.plugin_outputs(root, report_host, '14272')
   print(f'All findings for Netstat Portscanner (SSH): \n{pidos_14272}')
