CVE-2025-43989

Estado: AplazadaMedia (6.5)—

The /goform/formJsonAjaxReq POST endpoint of Shenzhen Tuoshi NR500-EA RG500UEAABxCOMSLICv3.4.2731.16.43 devices mishandles the set_timesetting action with the ntpserver0 parameter, which is used in a system command. By setting a username=admin cookie (bypassing normal session checks), an unauthenticated attacker can use that parameter to execute arbitrary OS commands.
