CVE-2024-6943Network attack vector

Authenticated code execution via PHAR image deserialization

Published Jul 21, 2024 · Updated Aug 1, 2024

Deserialization in CRMEB 5.0 through 5.4 allows remote authenticated users to execute code through the product-image download workflow. The downloadImage function in app/services/product/product/CopyTaobaoServices.php processes a supplied PHAR resource as an image, causing PHP to deserialize attacker-controlled archive metadata. A low-privileged session can reach the network path, and successful exploitation runs attacker-controlled code in the web application's context.
