FreeFloat FTP Server Buffer Overflow Vulnerability in STATUS Command Handler

A critical buffer overflow vulnerability has been identified in FreeFloat FTP Server version 1.0. The issue arises in an unknown function within the STATUS Command Handler component, allowing remote exploitation. The vulnerability has been publicly disclosed and could be actively exploited.

Impact

Exploitation of this vulnerability leads to a buffer overflow, which can commonly result in arbitrary code execution or causing a denial-of-service condition.

Reproduction

The vulnerability can be reproduced by sending a crafted STATUS command that includes a payload designed to overflow the buffer. This can be done using a TCP connection to the FTP server's port 21. The exploit payload must be carefully crafted to include the desired shellcode after the overwritten return address, which should be set to a location that allows execution of the injected code.
