**Name of the Vulnerable Software and Affected Versions**
Addonics NAS Adapter NASU2FW41 with loader 1.17
**Description**
The issue is related to multiple buffer overflows in the FTP server, which can be exploited by remote attackers to cause a denial of service, specifically a TCP/IP outage. This can be achieved by sending long arguments to certain commands, including the `XRMD`, `delete`, `RNFR`, or `RNTO` command.
**Recommendations**
For Addonics NAS Adapter NASU2FW41 with loader 1.17, consider restricting access to the FTP server until a fix is available.

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
