CVE-2026-90702 Details
Description
A flaw has been found in D-Link DWR-M921 1.1.52. Impacted is the function system of the file /boafrm/formDiskFormat. This manipulation of the argument partition causes os command injection. The attack may be initiated remotely. The exploit has been published and may be used.
An OS command injection vulnerability has been identified in the D-Link DWR-M921 router, specifically in the firmware version 1.1.52. The issue arises in the '/boafrm/formDiskFormat' handler, where the 'partition' parameter is manipulated without proper sanitization, allowing authenticated users to inject commands that are executed with root privileges. This vulnerability can be exploited remotely.
Users are advised to apply a strict whitelist for the 'partition' and 'systype' parameters, rejecting all shell metacharacters and using C library calls for command execution instead of concatenating strings and using the 'system()' function.
