CVE-2021-21015Network attack vector

Admin code execution via customer attribute command injection

Published Feb 11, 2021 · Updated Sep 17, 2024

OS command injection in Adobe Commerce 2.4.1 and earlier allows remote authenticated users to execute code via the customer attribute save controller. Adobe identifies that controller as the injection locus but does not disclose the accepted input, command-construction operation, or missing neutralization. Exploitation requires access to the Admin console with administrative privileges and executes commands in the Commerce server's security context.
