Tenda W3002R/A302/W309R wireless routers version V5.07.64_en contain a cookie session weakness vulnerability that allows unauthenticated attackers to modify DNS settings by exploiting insufficient session validation. Attackers can send GET requests to the /goform/AdvSetDns endpoint with a crafted admin language cookie to change primary and secondary DNS servers, redirecting user traffic to malicious DNS servers.
