CVE-2020-10541Network attack vector

Unauthenticated code execution via crafted API request

Published Mar 13, 2020 · Updated Aug 4, 2024

Remote code execution in Zoho ManageEngine OpManager before 12.4.179 allows remote attackers to execute code via a crafted v1 API request. The Mail Server Settings v1 API passes the crafted request into obsolete code that executes attacker-controlled code; the exact unsafe operation is undisclosed. No authentication or user interaction is required, and successful exploitation runs code in the OpManager server's security context.
