Authenticated code execution via unchecked MKD argument
Published Jan 16, 2024 · Updated Jun 2, 2025
Stack buffer overflow in KMiNT21 Software EasyFTP Server 1.7.0.2 allows remote authenticated users to execute arbitrary code via MKD. The MKD command handler copies an oversized directory-name argument into a 264-byte stack buffer without enforcing its length. An FTP account permitted to create directories is required, and successful exploitation runs code with the server process's privileges.
