Description: A critical issue affects the function cgi FMT Std2R5 1st DiskMGR of the file /cgi-bin/hd config.cgi in the component HTTP POST Request Handler. The manipulation of the argument f source dev leads to command injection. The attack may 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 the product is end-of-life.

Recommendations: As a temporary workaround, consider disabling the cgi FMT Std2R5 1st 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 argument f source dev in the affected HTTP POST Request Handler until the issue is resolved. Retire and replace the affected products, as they are no longer supported by the maintainer.
