CVE-2026-90703 Details
Description
A vulnerability has been found in D-Link DWR-M921 1.1.52. The affected element is the function system of the file /boafrm/formDiskCreateShare. Such manipulation of the argument folderpath leads to os command injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
An OS command injection vulnerability has been identified in the D-Link DWR-M921 router, specifically in firmware version 1.1.52. The issue arises in the disk share management feature, where the 'folderpath' parameter can be manipulated to inject malicious commands. This vulnerability can be exploited remotely, but requires authentication.
It is recommended to apply a strict whitelist for the 'folderpath' and 'foldername' parameters, allowing only specific path characters and rejecting all shell metacharacters. Additionally, use the 'mkdir()' C API instead of executing commands through the system() function, and write configuration changes after creating directories to avoid command injection risks.
