PCMan FTP Server Buffer Overflow Vulnerability in CONF Command Handler

A critical buffer overflow vulnerability has been identified in PCMan FTP Server version 2.0.7. This issue arises in the CONF command handler, where unknown code is susceptible to manipulation, allowing for 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 payload through the FTP 'CONF' command. The payload must be designed to overflow the buffer, potentially allowing for code execution. This can be done using a script or tool that automates the process of connecting to the FTP server and sending the malicious payload.
