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 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

The `getObjectByToken` function in `Newsletter.php` in the `Pimcore_Tool_Newsletter` module in pimcore 1.4.9 through 2.0.0 does not properly handle an object obtained by unserializing Lucene search data, which allows remote attackers to conduct PHP object injection attacks and execute arbitrary code via vectors involving a `Zend_Pdf_ElementFactory_Proxy` object and a pathname with a trailing `\0` character.
