Falcon Spotlight Vulnerabilities samples

The examples within this folder focus on leveraging CrowdStrike's Falcon Spotlight Vulnerabilities API.

Identify hosts with vulnerabilities by CVE

Retrieves a list of hosts with vulnerabilities matching the CVE(s) specified. Also provides remediation recommendations when available.

Dependencies

This sample is dependent upon the python-tabulate library.

Installing tabulate

Tabulate can be installed using the Python Package Index:

python3 -m pip install tabulate

Running the program

In order to run this demonstration, you you will need access to CrowdStrike API keys with the following scopes:

Service Collection
Scope

Hosts

READ

Spotlight Vulnerabilities

READ

Execution syntax

The following command will retrieve a list of hosts matching the specified CVE.

Basic usage

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c CVE-2021-22947

You do not need to prepend the CVE- string to your CVE ID. Both formats are accepted.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c 2021-22947

You can search for multiple CVEs by passing a comma delimited string for the -c argument.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c CVE-2021-22947,CVE-2021-36085

Excluding columns

You can exclude columns from the result display using the -x argument.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c CVE-2021-22947 -x cve_description

Enabling the progress indicator

To show a progress indicator, use the -p option.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c 2021-22947 -p

Changing the sort

By default, results are sorted by creation date (created_on). You can specify the column to sort by using the -o argument.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c 2021-22947 -o local_ip

Available sort columns

  • cve

  • score

  • severity

  • cve_description

  • created_on

  • updated_on

  • hostname

  • local_ip

  • os_version

  • service_provider

  • remediation

By default, results are sorted in ascending order. You can change this behavior using the -r argument.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c 2021-22947 -o local_ip -r

Changing the tabular display format

Multiple formats are supported for displaying results. You can change format using the -f argument. Invalid selections are ignored.

python3 find_hosts_by_cve.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -c 2021-22947 -f simple

Available table formats

  • plain

  • simple

  • github

  • grid (Default)

  • fancy_grid

  • pipe

  • orgtbl

  • jira

  • presto

  • pretty

  • psql

  • rst

  • mediawiki

  • moinmoin

  • youtrack

  • html

  • unsafehtml

  • latex

  • latex_raw

  • latex_booktabs

  • latex_longtable

  • textile

  • tsv

Command-line help

Command-line help is available via the -h argument.

python3 find_hosts_by_cve.py -h
usage: find_hosts_by_cve.py [-h] -k CLIENT_ID -s CLIENT_SECRET [-b BASE_URL] -c CVE [-x EXCLUDE] [-f FORMAT] [-o SORT] [-r] [-p]

Retrieve hosts by CVE vulnerability.
