SYSTEM code execution via unrestricted FTP upload
Published Aug 5, 2025 · Updated Apr 7, 2026
Unrestricted file upload in FreeFloat FTP Server allows remote attackers to execute code as SYSTEM through unauthenticated FTP access. The FTP file-handling logic accepts empty credentials, fixes the session root at C:, and permits STOR to write executable and MOF files into system directories. Any network client that can reach the FTP service can place a MOF in wbem\mof, where WMI processes it without user interaction.
