How to Fix CVE-2019-10867

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

pimcore/pimcore fixed: 5.7.1 
Upgrade pimcore/pimcore to 5.7.1
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 pimcore/pimcore

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-10867, inspect your project dependencies for Pimcore/pimcore:

inspect dependencies for pimcore/pimcore

Analyze the terminal output to locate any version of Pimcore/pimcore in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.7.1), 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Pimcore/pimcore, 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

An issue was discovered in Pimcore before 5.7.1. An attacker with classes permission can send a POST request to `/admin/class/bulk-commit`, which will make it possible to exploit the unserialize function when passing untrusted values in the data parameter to `bundles/AdminBundle/Controller/Admin/DataObject/ClassController.php`.
