CVE-2023-3306Public exploitNetwork attack vector

Unauthenticated administrator takeover via password-change path

Published Jun 18, 2023 · Updated Dec 16, 2024

Improper access control in Ruijie Networks RG-EW1200G EW_3.0(1)B11P204 allows remote attackers to change the administrator password. The bundled app.09df2a9e44ab48766f5f.js exposes an administrative password-change path that accepts a replacement without an authenticated session. Network access to the web interface is the reported gate, and changing the credential grants control of administrative functions.
