CVE-2023-32526Network attack vector

Arbitrary file creation via unvalidated certificate upload

Published Jun 26, 2023 · Updated Dec 4, 2024

Unrestricted file upload in Trend Micro Mobile Security for Enterprise 9.8 SP5 allows remote authenticated users to create arbitrary files. The web/widgetforsecurity set_certificates_config action fails to validate user-supplied upload data before writing it as a file. Low-privileged code execution is required; chaining the upload with other flaws enables code execution as IUSR.
