NAME

NIST::NVD::Query - Query the NVD database

VERSION

Version 1.00.00

SYNOPSIS

Query vulnerability data in the NVD database

    use NIST::NVD::Query;

    # use convert_nvdcve to generate db files from the XML dumps at
    # http://nvd.nist.gov/download.cfm

    my( $path_to_db, $path_to_idx_cpe ) = @ARGV;

    my $q = NIST::NVD::Query->new( store => $some_store,
                                   %args
                                  );

    # Given a Common Platform Enumeration urn, returns a list of known
    # CVE IDs

    my $cve_id_list = $q->cve_for_cpe( cpe => 'cpe:/a:zaal:tgt:1.0.6' );

    my @entry;

    foreach my $cve_id ( @$cve_id_list ){

      # Given a CVE ID, returns a CVE entry

      my $entry = $q->cve( cve_id => $cve_id );
      push( @entry, $entry );

      print $entry->{'vuln:summary'};
    }

SUBROUTINES/METHODS

new

Required arguments:

    database: path to BDB database of NVD entries
    idx_cpe:  path to BDB database of mappings from CPE URNs to CVE IDs

Example

    my $q = NIST::NVD::Query->new( database => $path_to_db,
                                   idx_cpe  => $path_to_idx_cpe,
