As an impact it is known to affect integrity. The summary by CVE is:

A Cross-Site Request Forgery (CSRF) vulnerability exists in the web management interface of the U-SPEED N300 Rounter V1.0.0. The device does not implement CSRF protection mechanisms such as anti-CSRF tokens or strict Origin/Referer validation for administrative API endpoints. An attacker can craft a malicious webpage that sends forged HTTP requests to configuration endpoints. If an authenticated administrator visits the malicious webpage, the victim's browser automatically includes the valid session cookie in the request, allowing the router to process the request as a legitimate administrative action.
