CVE-2026-90706 Details
Description
A vulnerability was identified in D-Link DWR-M921 1.1.52. This impacts the function formWsc of the file /boafrm/formWsc. The manipulation of the argument targetAPSsid leads to os command injection. The attack is possible to be carried out remotely. The exploit is publicly available and might 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 web interface route '/boafrm/formWsc', where the 'targetAPSsid' parameter is not properly sanitized before being passed to a system command. This vulnerability can be exploited remotely, but requires authentication via a web session cookie.
To address this vulnerability, D-Link should implement proper input validation for the 'targetAPSsid' parameter, allowing only visible ASCII characters and rejecting special characters that could be used for command injection. Additionally, the existing filter function should be enhanced to cover the currently unescaped characters or replaced with a parameterized execution approach.
