Security flaw parser for upstream security advisories

Project description

Travis CI test status

Upstream repository:

This library allows you to parse data from security advisories of certain projects to extract information about security issues. The parsed information includes metadata such as impact, CVSS score, summary, description, and others; for a full list, see the advisory_parser/ file.

DISCLAIMER: Much of the advisory parsing is fairly fragile. Because web pages change all the time, it is not uncommon for parsers to break when a page is changed in some way. Also, the advisory parsers only work with the latest version of the advisory pages.

The need for parsing raw security advisories in this way could be avoided if vendors provided their security pages in a machine readable (and preferably standardized) format. An example of this would be Red Hat’s security advisories that can be pulled in from a separate Security Data API (RHSA-2016:1883.json) or downloaded as an XML file (cvrf-rhsa-2016-1883.xml), or OpenSSL’s list of issues available in XML (vulnerabilities.xml).

If you are a vendor or an upstream project owner interested in providing your security advisories in a machine readable format and don’t know where to start, feel free to reach out to
