CVE-2025-34057Known exploitationPublic exploitNetwork attack vector

Administrative credential disclosure via unauthenticated POST request

Published Jul 2, 2025 · Updated Nov 13, 2025

Information disclosure in Ruijie Networks RG-NBR Series Routers allows remote attackers to retrieve plaintext administrative credentials. The /WEB_VMS/LEVEL15/ endpoint processes a crafted POST request with modified Cookie headers and formatted command, strurl, mode, and signname parameters without enforcing authentication. Network access to the management endpoint is sufficient, and successful exploitation exposes administrative account credentials without reported integrity or availability impact.
