cve-ape 1.1.0

CVE scanner which can process pkglists

cve-ape

CVE Ape is a fairly simple, free and open source tool which helps to find all registred at the National Vulnerability Database (NVD) list of Common Vulnerabilities and Exposures (CVEs). The tool creates a local copy of NVD and CVEs databases and allows to search for registered CVEs by package name, vendor name or over OS libs and packages listed in the package list.

Main usage of this tool is to help with review of linux based IOT devices, but could be also integrated at the CI/CD pipelines to maintain better level of security.

This is not very precise tool because is not checking any backports nor vendors if not supplied specifically.

The tool is downloading and creating a local CVE database at ~/.cache/cve-ape/ folder. It can be used offline, but only after a first update as it has to create a database.

How to install

It works only with python3

Source code is here: https://github.com/Baalmor/cve-ape

or just use pip

pip install cve-ape

How to use

You need to generate a pkglist yourself first. Currently only CSV and a list format are supported. Text list format Example:

curl-7.77.0-r0
dbus-1.12.20-r0
dbus-libs-1.12.20-r0
device-mapper-libs-2.02.187-r0
dhcpcd-8.1.9-r0
disk-utils-0.3.0_rc1-r0
dnsmasq-2.85-r0

You can run a tool using this command: cve-ape -L pkglist.txt

  Arguments related to NVD Database and Cache Configuration

  -n {api,json}, --nvd {api,json}
                        choose method for getting CVE lists from NVD
  -u {now,daily,never,latest}, --update {now,daily,never,latest}

  --nvd-api-key NVD_API_KEY
                        specify NVD API key (used to improve NVD rate limit)

Input:
  -L PACKAGE_LIST, --package-list PACKAGE_LIST
                        provide a package list.
  -C CSV_FORMAT, --csv-format CSV_FORMAT
                        comma separated headers if file is a CSV, or comma
                        separated column numbers started from 0 where the

  -d CSV_DELIMITER, --csv-delimiter CSV_DELIMITER
                        a delimiter used in the csv file. Default: ";"
