Logitec LAN-W300N/R routers with firmware before 2.27 do not properly restrict login access, which allows remote attackers to obtain administrative privileges and modify settings via vectors related to PPPoE authentication.

Improper check or handling of exceptional conditions in LOGITEC LAN-W300N/RS allows a remote attacker to cause a denial-of-service (DoS) condition by sending a specially crafted URL.

Cross-site request forgery (CSRF) vulnerability in LOGITEC LAN-W300N/RS allows remote attackers to hijack the authentication of administrators via a specially crafted URL. As a result, unintended operations to the device such as changes of the device settings may be conducted.
