Description: A critical vulnerability was found in the affected D-Link products. The issue affects the function cgi s3 modify of the file /cgi-bin/s3.cgi of the component HTTP POST Request Handler. The manipulation of the argument f job name leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. Note that this vulnerability only affects products that are no longer supported by the maintainer, and the vendor has confirmed that the product is end-of-life.

Recommendations: As a temporary workaround, consider disabling the cgi s3 modify function until a replacement product is installed. Restrict access to the /cgi-bin/s3.cgi file to minimize the risk of exploitation. Avoid using the f job name 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 no longer supported by the maintainer. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
