OpenMage LTS's Phar Deserialization leads to Remote Code Execution
Summary
OpenMage LTS's Phar Deserialization leads to Remote Code Execution
Original description
The description as published by the source.
Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to version 20.17.0, PHP functions such as getimagesize(), file_exists(), and is_readable() can trigger deserialization when processing phar:// stream wrapper paths. OpenMage LTS uses these functions with potentially controllable file paths during image validation and media handling. An attacker who can upload a malicious phar file (disguised as an image) and trigger one of these functions with a phar:// path can achieve arbitrary code execution. Version 20.17.0 patches the issue.
