CVE-2020-26252Network attack vector

Remote code execution via unsafe layout actions

Published Jan 20, 2021 · Updated Aug 4, 2024

OpenMage LTS before 19.4.10 and 20.0.0 through 20.0.5 allows remote authenticated users to execute code through product layout XML. Mage_Core_Model_Layout::_generateAction invokes block methods named by layout XML without rejecting dangerous Template::fetchView and Topmenu::render actions. Exploitation requires an administrator permitted to update product data, enabling an uploaded executable file to run with the web application’s privileges.
