Summary

A significant command injection vulnerability exists in several D-Link network storage devices, specifically in the cgi_FMT_Std2R5_2nd_DiskMGR function within the /cgi-bin/hd_config.cgi file. This vulnerability allows an attacker to manipulate the f_source_dev argument, leading to remote execution of arbitrary commands. The affected models, which include various DNS series and DNR series devices, are no longer supported by D-Link and are considered end-of-life. Users are strongly recommended to retire affected devices and transition to supported alternatives to mitigate potential security risks.
