Recommendation: Plan a near-term fix — a public PoC already exists.

NICO-FTP 3.0.1.19 contains a structured exception handler buffer overflow vulnerability that allows remote attackers to execute arbitrary code by sending crafted FTP commands. Attackers can connect to the FTP service and send oversized data in response handlers to overwrite SEH pointers and redirect execution to injected shellcode.
