HIGH

CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Description

An authentication logic vulnerability in multiple TP-Link range extenders allows an unauthenticated attacker on an adjacent network to manipulate a login parameter and reset the administrator password due to insufficient validation.

Successful exploitation allows an attacker to obtain full administrative control of the affected device, potentially impacting on confidentiality, integrity, and availability.
