How to Fix CVE-2023-41892

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

craftcms/cms fixed: 4.4.15
Upgrade craftcms/cms to 4.4.15
Verify Direct and Transitive Dependencies

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

inspect dependencies for craftcms/cms

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-41892, inspect your project dependencies for Craftcms/cms:

inspect dependencies for craftcms/cms

Analyze the terminal output to locate any version of Craftcms/cms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.15), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Craftcms/cms, 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 This is a high-impact, low-complexity attack vector. Users running Craft installations before 4.4.15 are encouraged to update to at least that version to mitigate the issue. ### Mitigations * This has been fixed in Craft 4.4.15. You should ensure you’re running at least that version. * Refresh your security key in case it has already been captured. You can do that by running the `php craft setup/security-key` command and copying the updated `CRAFT_SECURITY_KEY` environment variable to all production environments. * If you have any other private keys stored as environment variables (e.g., S3 or Stripe), refresh those as well. * Out of an abundance of caution, you may want to force all your users to reset their passwords in case your database was compromised. You can do that by running `php craft resave/users --set passwordResetRequired --to "fn() => true"`. ### References https://github.com/craftcms/cms/commit/c0a37e15cc925c473e60e27fe64054993b867ac1#diff-47dd43d86f85161944dfcce2e41d31955c4184672d9bd9d82b948c6b01b86476 https://github.com/craftcms/cms/commit/7359d18d46389ffac86c2af1e0cd59e37c298857 https://github.com/craftcms/cms/commit/a270b928f3d34ad3bd953b81c304424edd57355e https://github.com/craftcms/cms/blob/develop/CHANGELOG.md#4415---2023-07-03-critical
