CVE-2021-36025Network attack vector

Remote code execution via crafted customer file

Published Sep 1, 2021 · Updated Sep 17, 2024

Improper input validation in Adobe Commerce 2.4.2 and earlier allows remote authenticated users to execute code via crafted customer files. The customer-detail save handler accepts a specially crafted file without adequate validation, allowing server-side code execution. An authenticated administrator must reach the customer-management interface; successful exploitation can compromise confidentiality, integrity, and availability through remote code execution.
