LOW 2.1

DescriptionCVE.org

A weakness has been identified in D-Link DWR-M920 up to 1.1.50. The affected element is the function sub_4155B4 of the file /boafrm/formLtefotaUpgradeFibocom. This manipulation of the argument fota_url causes command injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be exploited.

AnalysisAI

Remote command injection in D-Link DWR-M920 routers allows authenticated attackers with low privileges to execute arbitrary commands on the device. The flaw exists in the fota_url parameter of the formLtefotaUpgradeFibocom handler in firmware versions up to 1.1.50. Exploit code is publicly available, but no evidence of active exploitation exists, and EPSS suggests low exploitation probability.
