Migrating from the DAST version 4 browser-based analyzer to DAST version 5

DAST version 5 replaces DAST version 4. This document serves as a guide to migrate from the DAST version 4 browser-based analyzer to DAST version 5.

Follow this migration guide if all the following conditions apply:

  1. You use GitLab DAST to run a DAST scan in a CI/CD pipeline.
  2. The DAST CI/CD job is configured by including either of the DAST templates DAST.gitlab-ci.yml or DAST.latest.gitlab-ci.yml.
  3. The CI/CD variable DAST_VERSION is not set or is set to 4 or less.
  4. The CI/CD variable DAST_BROWSER_SCAN is set to true.

Migrate to DAST version 5 by reading the following sections and making the recommended changes.

DAST analyzer versions

DAST comes in two major versions: 4 and 5. Effective from the third GitLab 17.0 breaking change window, 2024-05-06 09:00 UTC to 2024-05-08 22:00 UTC, the DAST templates DAST.gitlab-ci.yml and DAST.latest.gitlab-ci.yml use DAST version 5 by default. You can continue using DAST version 4, but you should do so only as an interim measure while migrating to DAST version 5. For details, see Continuing to use version 4.

Each DAST major version runs different analyzers:

  • DAST version 4 can run either the proxy-based or browser-based analyzer, and uses the proxy-based analyzer by default.
  • DAST version 5 runs only the browser-based analyzer.

DAST version 5 uses a set of new CI/CD variables. Aliases have been created for the DAST version 4 variables' names.

Changes to make:

  • To test your DAST scan using DAST version 5 in GitLab 16.11 and earlier, set the CI/CD variable DAST_VERSION to 5.

Continuing to use version 4

You can use the DAST version 4 browser-based analyzer until GitLab 18.0. Bugs and vulnerabilities in this legacy analyzer will not be fixed.

Changes to make:

  • To continue using DAST version 4, set the CI/CD variable DAST_VERSION variable to 4.

Artifacts

GitLab 17.0 automatically publishes artifacts produced by DAST version 5 to the DAST CI job.

Changes to make:

  • Remove artifacts from the CI job definition if you have overridden it to expose the file log, crawl graph, or authentication report.
  • CI/CD variables DAST_BROWSER_FILE_LOG_PATH and DAST_FILE_LOG_PATH are no longer required.

Vulnerability check coverage

Browser-based DAST version 4 uses proxy-based analyzer checks for active checks not included in the browser-based analyzer. Browser-based DAST version 5 does not include the proxy-based analyzer, so there is a gap in check coverage when migrating to version 5.

There are three proxy-based active checks that the browser-based analyzer does not cover. Adding more checks to provide complete coverage is in active development, you may remain on DAST version 4 until they are complete. See Continuing to use version 4.

Remaining checks:

  • CWE-79: Cross-site Scripting (XSS)
  • CWE-384: Session Fixation
  • CWE-16: TRACE HTTP

Follow the progress of the remaining checks in the epic Remaining active checks for BBD.
