TITLE

TP-Link TL-SG108E Access control vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2017-011673

DESCRIPTION

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. TP-Link TL-SG108E Contains an access control vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The TP-LinkTL-SG108E is a Gigabit Ethernet switch from China's TP-LINK. An authentication vulnerability exists in the TP-LinkTL-SG108E1.0.0 version due to the weaker access control method used by the program. An attacker could exploit the vulnerability to access the device
