Performing a manipulation of the argument callback_url/sync_interval results in os command injection. The attack can be initiated remotely. The exploit has been made public and could be used.
A command injection vulnerability has been identified in the D-Link DNS-340L ShareCenter NAS device running firmware version 1.01B04. The issue resides in the CGI handler file 'dropbox.cgi', which is part of the Dropbox backup and sync management feature. The vulnerability allows authenticated users to inject arbitrary shell commands by manipulating the 'callback_url' and 'sync_interval' POST parameters. These injected commands are executed with the privileges of the CGI process user, potentially leading to unauthorized command execution on the device.
Users are advised to update to a version of the D-Link DNS-340L firmware that addresses this vulnerability. Consult the D-Link support website or contact D-Link customer service for information on available firmware updates.
