How to Fix CVE-2024-40637

To remediate this vulnerability, upgrade all affected Dbt core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dbt-core fixed: 1.6.14
pip install dbt-core>=1.6.14
dbt-core fixed: 1.7.14
pip install dbt-core>=1.7.14
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

pip show dbt-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-40637, inspect your installed packages using pip:

pip show dbt-core

Analyze the terminal output to locate any version of Dbt core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.14), your application is affected.

Note: The pip show dbt-core command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Dbt core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact _What kind of vulnerability is it? Who is impacted?_ When a user installs a [package](https://docs.getdbt.com/docs/build/packages) in dbt, it has the ability to override macros, materializations, and other core components of dbt. This is by design, as it allows packages to extend and customize dbt's functionality. However, this also means that a malicious package could potentially override these components with harmful code. ### Patches _Has the problem been patched? What versions should users upgrade to?_ Fixed on 1.8.0, and patched for 1.6.14 and 1.7.14 releases. ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ Previously, a materialization defined in a package that shared a name with one of the built-in materializations would be preferred by default, without user action which is surprising and makes it more difficult to detect the insecure behaviour. We've changed the default behaviour to require explicit overrides by users in `1.8.0`, and provided the ability to opt-out of built-in materialization overrides in 1.6 and 1.7 via the `flags.require_explicit_package_overrides_for_builtin_materializations: False` configuration in `dbt_project.yml` Versions older than 1.6 are EOL. ### References _Are there any links users can visit to find out more?_ * dbt documentation: https://docs.getdbt.com/reference/global-configs/legacy-behaviors#behavior-change-flags * https://www.elementary-data.com/post/are-dbt-packages-secure-the-answer-lies-in-your-dwh-policies * https://www.equalexperts.com/blog/tech-focus/are-you-at-risk-from-this-critical-dbt-vulnerability/ * https://tempered.works/posts/2024/07/06/preventing-data-theft-with-gcp-service-controls/
