CVE-2025-0479Network attack vector

Session hijacking via insecure cookie flags

Published Jan 20, 2025 · Updated Jan 21, 2025

Cookie security misconfiguration in CP PLUS CP-XR-DE21-S firmware DE21_S_india_hx806_1.057.043_0023 allows remote attackers to hijack sessions. The web interface omits Secure and HttpOnly protections on sensitive cookies, enabling interception during an HTTP session and access through client-side code. Exploitation requires active user interaction and a position capable of intercepting a live session; stolen session data can expose sensitive information and compromise the device.
