CVE-2022-22929Public exploitNetwork attack vector

Code execution via malicious template ZIP rendering

Published Jan 20, 2022 · Updated Aug 3, 2024

Arbitrary file upload in Mingsoft MCMS 5.2.4 allows remote attackers to execute code via a crafted template ZIP. The New Template module automatically extracts the uploaded archive and renders its FreeMarker content without blocking executable directives. The published procedure uses the system-settings template manager, but the public record does not establish whether that interface enforces authentication.
