Summary

A serious command injection vulnerability has been identified in multiple D-Link Network Attached Storage (NAS) devices, including models DNS-120, DNS-320, and DNS-1550-04, among others. This flaw resides in the cgi_FMT_Std2R5_1st_DiskMGR function of the HTTP POST request handler in the hd_config.cgi file. By manipulating the f_source_dev parameter, attackers can execute arbitrary commands on the vulnerable devices. This vulnerability is particularly concerning as it can be exploited remotely, thereby increasing its potential risk to networks employing affected devices that are no longer supported by D-Link. Users are strongly advised to retire any end-of-life products and replace them with supported alternatives to mitigate security risks.
