CVE-2021-46063Network attack vector

Template injection via Template Management module

Published Feb 18, 2022 · Updated Aug 4, 2024

Server-side template injection in Mingsoft MCMS 5.2.5 allows remote attackers to execute injected template expressions through the Template Management module. The module evaluates attacker-controlled template input on the server instead of treating it as inert data, creating a server-side template injection condition. Unauthenticated network access is sufficient; the record indicates integrity and availability impact without a stated data-read impact.
