Detailsinfo

A vulnerability was found in Shenzhen Tuoshi NR500-EA 3.4.2731.16.43. It has been classified as critical. This affects the function set_timesetting of the file /goform/formJsonAjaxReq. The manipulation of the argument ntpserver0 with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2025-43989 since 04/21/2025. The exploitability is told to be easy.
