Description
KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1 mishandle configuration management. Once any user is logged in and maintains an active session, an attacker can directly query the backup endpoint and download a full configuration archive. This archive contains sensitive files such as /etc/shadow, enabling credential recovery and potential full compromise of the device.
