How can this vulnerability impact me? :
This vulnerability can have severe impacts as it allows remote attackers to execute arbitrary code without any privileges or user interaction.
- Attackers can gain unauthorized remote access to the affected system by executing a bind shell on port 5150.
- This can lead to full system compromise, data theft, or further exploitation within the network.
- Because the vulnerability is remotely exploitable with no privileges required, it poses a high risk to affected systems.

The vulnerability exists in Ayukov NFTP client version 1.71, specifically in the handling of the SYST command. It is a buffer overflow vulnerability that allows remote attackers to send a specially crafted SYST command with an oversized payload. This triggers the buffer overflow and enables the attacker to execute arbitrary code on the affected system.
In particular, the attacker can execute a bind shell on port 5150, which means they can gain remote control over the system through that port.
