What is CVE-2025-34057?

An information disclosure vulnerability affects Ruijie NBR series routers, specifically models NBR2000G, NBR1300G, and NBR1000. The vulnerability can be exploited through the /WEB_VMS/LEVEL15/ endpoint, where an unauthenticated attacker, by forging a specific POST request with adjusted Cookie headers and tailored parameters, is capable of retrieving sensitive administrative account credentials in plaintext. This security flaw arises from inadequate authentication mechanisms and insecure backend logic, leading to the potential unauthorized access to critical user information.

Affected Version(s)

NBR Router 0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
