Weak access control methods on the TP-Link TL-SG108E 1.0.0 allow any user on a NAT network with an authenticated administrator to access the device without entering user credentials. The authentication record is stored on the device; thus if an administrator authenticates from a NAT network, the authentication applies to the IP address of the NAT gateway, and any user behind that NAT gateway is also treated as authenticated.
Weak access controls in the Device Logout functionality on the TP-Link TL-SG108E v1.0.0 allow remote attackers to call the logout functionality, triggering a denial of service condition.
