This GitHub public repository ( https://github.com/oasis-open/csaf-parser ) was created at the request of the OASIS Common Security Advisory Framework (CSAF) TC as an OASIS TC Open Repository to support development of open source resources related to Technical Committee work.
**NOTE**: The current version of this parser only supports [CVRF 1.2 (XML-based specification)](http://docs.oasis-open.org/csaf/csaf-cvrf/v1.2/cs01/csaf-cvrf-v1.2-cs01.html). It does not support the [CSAF 2.0 JSON schema](https://github.com/oasis-tcs/csaf/blob/master/csaf_2.0/json_schema/csaf_json_schema.json). To obtain information about several tools to parse, create, and validate CSAF 2.0 content go to https://csaf.io.While this TC Open Repository remains associated with the sponsor TC, its development priorities, leadership, intellectual property terms, participation rules, and other matters of governance are separate and distinct from the OASIS TC Process and related policies.
All contributions made to this TC Open Repository are subject to open source license terms expressed in the BSD-3-Clause License. That license was selected as the declared "Applicable License" when the TC Open Repository was created.
As documented in "Public Participation Invited", contributions to this OASIS TC Open Repository are invited from all parties, whether affiliated with OASIS or not. Participants must have a GitHub account, but no fees or OASIS membership obligations are required. Participation is expected to be consistent with the OASIS TC Open Repository Guidelines and Procedures, the open source LICENSE designated for this particular repository, and the requirement for an Individual Contributor License Agreement that governs intellectual property.
Statement of Purpose for this OASIS TC Open Repository (csaf-parser) as proposed and approved [bis] by the TC:
The CSAF Parser (and validator) under development in this repository is a software tool for parsing and checking the syntax of the Common Vulnerability Reporting Framework (CVRF) machine readable security advisory content. The repository contains source code and associated documentation for the tool. The CSAF Parser can be used as a command-line tool or as a Python library which can be included in other applications.
[Earlier incarnations of the parser code included cvrf-util and Mike Schiffman's cvrfparse]
One fairly common use-case would be to query a document and pull out the unique set of products with related fields from all vulnerabilities and save to excel file as shown below:
`python cvrf_util.py --file examples/1.1/ms_cvrf.xml --schema schemata/cvrf/1.1/cvrf.xsd --cvrf-version 1.1 --output-format csv --output-file ms_cvrf.csv --vuln ProductID --include-related-product-elements --unique-products --related-product-tags all`
| Where the following command line parameters were applied: | |
| --file examples/1.1/ms_cvrf.xml | Specify the document we are parsing |
| --schema schemata/cvrf/1.1/cvrf.xsd | Specify the schema |
| --cvrf-version 1.1 | Specify the CVRF version |
| --output-format csv | Specify output format to CVS |
| --output-file ms_cvrf.csv | Specify the output file |
| --vuln ProductID | Specify elements to parse |
| --include-related-product-elements | Tell output to include related product elements |
| --unique-products | Specify that we want unique product rows per vulnerability |
| --related-product-tags all | Specify which related product element tags to include for each product row |
Another common example is to query a document and parse out all of the elements in each vulnerability and save to html file as shown below:
`python cvrf_util.py --file examples/1.1/ms_cvrf.xml --cvrf-version 1.1 --output-format html --output-file ms_cvrf.html --vuln Vulnerability --cvrf all --prod all`
| Where the following command line parameters were applied: | |
| --file examples/1.1/ms_cvrf.xml | Specify the document we are parsing |
| --cvrf-version 1.1 | Specify the CVRF version |
| --output-format html | Specify output format to HTML |
| --output-file ms_cvrf.html | Specify the output file |
| --vuln Vulnerability | Specify elements to parse |
| --cvrf all | Specify elements to parse |
| --prod all | Specify elements to parse |
