CVE-2021-44650Network attack vector

Authenticated command execution via proxy-setting injection

Published Jan 12, 2022 · Updated Aug 4, 2024

Command injection in Zoho ManageEngine M365 Manager Plus before build 4419 allows remote authenticated users to execute commands. A REST API URL processes updates in the Admin ProxySettings and Tenant ProxySettings components, but the affected parameter and faulty code operation are undisclosed. Administrative authentication is required, and successful exploitation executes commands in the application server's security context.
