CVE-2026-90705 Details
Description
A vulnerability was determined in D-Link DWR-M921 1.1.52. This affects the function formsysCmd of the file /boafrm/formsysCmd of the component Boa Dispatch Table. Executing a manipulation of the argument sysCmd can lead to os command injection. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized.
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 Boa Dispatch Table, within the function 'formSysCmd'. This vulnerability allows remote command injection by manipulating the 'sysCmd' argument, with no input filtering applied. The exploitation requires authentication, but the vulnerability can be reproduced on the emulated firmware.
It is recommended to remove the 'formSysCmd' handler or eliminate the 'system()' call that allows command execution. If a diagnostic feature is necessary, implement a strict whitelist of allowed commands and use 'execve' with an argument array instead of concatenating command strings.
