CVE-2025-68719 High · 8.8 CWE-200 Jan 8, 2026

Exposure of Sensitive Information in Kaysus Ks-wr3600 Firmware

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.

CVE-2025-68717 Critical · 9.4 CWE-287 Jan 8, 2026

Improper Authentication in Kaysus Ks-wr3600 Firmware

KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1 allow authentication bypass during session validation. If any user is logged in, endpoints such as /cgi-bin/system-tool accept unauthenticated requests with empty or invalid session values. This design flaw lets attackers piggyback on another user's active session to retrieve sensitive configuration data or execute privileged actions without authentication.

CVE-2025-68716 High · 8.4 CWE-284 Jan 8, 2026

Improper Access Control in Kaysus Ks-wr3600 Firmware

KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1 enable the SSH service enabled by default on the LAN interface. The root account is configured with no password, and administrators cannot disable SSH or enforce authentication via the CLI or web GUI. This allows any LAN-adjacent attacker to trivially gain root shell access and execute arbitrary commands with full privileges.
