Description: A critical vulnerability was found in the specified D-Link products. It affects the function cgi FMT R5 SpareDsk DiskMGR of the file /cgi-bin/hd config.cgi in the HTTP POST Request Handler component. The manipulation of the argument f source dev leads to command injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. This issue only affects products that are no longer supported by the maintainer, and the vendor has confirmed that these products are end-of-life.

Recommendations: As a temporary workaround, consider disabling the cgi FMT R5 SpareDsk DiskMGR function until a replacement is available. Restrict access to the /cgi-bin/hd config.cgi file to minimize the risk of exploitation. Avoid using the f source dev argument in the affected HTTP POST Request Handler until the issue is resolved. It is recommended to retire and replace the affected products as they are end-of-life. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
