CVE-2022-33320

Code execution via malicious project-file deserialization

Published Jul 20, 2022 · Updated Jan 9, 2026

Deserialization in affected GENESIS64, ICONICS Suite, and MC Works64 releases allows attackers to execute code via a crafted project file. The project-management function inadequately validates XML in a project configuration file before deserializing it, permitting embedded malicious code to execute. A user must load the file; affected releases are GENESIS64 and ICONICS Suite 10.97 through 10.97.1 and MC Works64 4.04E and earlier.
