CVE-2025-65212
CriticalSummary
NJHYST HY511 POE core (before 2.1) and plugins (before 0.1) have insufficient cookie verification, allowing an attacker to directly download the core configuration file without logging in. By reading the username and self-decrypted MD5 password, the attacker can log in to the backend.
Risk Assessment
Attackers can gain full device access, leading to confidentiality and integrity compromise of the configuration.
Recommendation
Upgrade device firmware to the latest version. Restrict access to the admin panel and enforce strong authentication.
Original NVD description (English source)
An issue was discovered in NJHYST HY511 POE core before 2.1 and plugins before 0.1. The vulnerability stems from the device's insufficient cookie verification, allowing an attacker to directly request the configuration file address and download the core configuration file without logging into the device management backend. By reading the corresponding username and self-decrypted MD5 password in the core configuration file, the attacker can directly log in to the backend, thereby bypassing the front-end backend login page.
