Nessus Vulnerability XML Parser v6

May 25th, 2010 Comments off

I found an error in the vulnerability worksheets.  So I fixed them and added the port scanning reporting found in the Nessus XML file.  Enjoy…parse_nessus_xml-for-blog.v6.pl

Nessus Vulnerability XML Parser

May 21st, 2010 19 comments

When I do security assessments, I always use Nessus.  Nessus is a great tool and is extremely helpful with one exception, the reporting.  While filtering is good in the new Flash interface, I still found myself needing to do something else.  So I have used Perl for many years and I figured it was time to start coding again.  I am by no means a Perl expert or even a programmer.  But I can hack-up some pretty good Perl code to parse text files. So that is what I did.

This the first Perl code I have ever released to the public.  So if you read it and would like to comment…please be gentle.

The parse-nessus.pl is a CLI only script.   The script does require a few modules that can be found on CPAN.  The required modules are: XML::TreePP, Data::Dumper, Spreadsheet::WriteExcel::Big, and Math::Round.  I used this on Snow Leopard, but all the modules I use should compile fine on any OS.  To install the modules from the command line use the “cpan” command, see below.

sudo cpan XML::TreePP
sudo cpan Data::Dumper
sudo cpan Spreadsheet::WriteExcel::Big
sudo cpan Math::Round
The script is designed to look for all the *.XML files in defined directory.  The directory is passed as an argument, if no directory is specified an error will be returned.  To see the version, then add the v|V|-v|-V and a version will be reported.  The script will create two files, the nessus_report.xls and Nessus_data_report.txt.  The Nessus_data_report.txt is a text version of the data found in the actual Nessus report, but only shows all the Severity 2 & 3 reports.  The nessus_report.xls is a multi spreadsheet workbook that contains all the findings from Nessus.  I then manually create a series of pivot tables as such.  I have the auto-sort on all columns and will be adding more formatting as time allows.
