Summary

Pimcore before versions 11.5.17 (LTS) and 12.3.7 calls PHP unserialize() on data from database columns and files without the allowed_classes restriction in multiple locations, including lib/Tool/Authentication.php. This enables object injection and remote code execution if an attacker can control the serialized data source.

Risk Assessment

An attacker can achieve remote code execution on the Pimcore server, leading to full system compromise.

Recommendation

Update Pimcore to version 11.5.17 (LTS) or 12.3.7. Restrict access to data sources that could be controlled by an attacker.

Original NVD description (English source)

Pimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.17 (LTS) and 12.3.7, multiple Pimcore locations call PHP's unserialize() on data from database columns and filesystem files without the allowed_classes restriction, including lib/Tool/Authentication.php, models/Site/Dao.php, models/DataObject/ClassDefinition/CustomLayout/Dao.php, models/Tool/TmpStore/Dao.php, models/Asset/WebDAV/Service.php, and admin-ui-classic-bundle/src/Helper/Dashboard.php, enabling object injection and remote code execution if an attacker can control the serialized data source. This issue is fixed in versions 11.5.17 (LTS) and 12.3.7.
