Technical Analysis
The Ebyte NA111-M firmware suffers from a Cross-Site Request Forgery (CWE-352) vulnerability. The web management interface fails to adequately verify the source or authenticity of requests, enabling an attacker without authentication to coerce an authenticated administrator into executing unintended actions by visiting a crafted webpage. This can result in unauthorized configuration modifications or denial of service conditions affecting device availability.
Potential Impact
Successful exploitation can lead to full compromise of device configuration and availability, as attackers can induce administrators to perform unauthorized changes or disrupt the device remotely. The CVSS 3.1 base score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No official patch or fix is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should avoid visiting untrusted web pages while authenticated to the device's management interface and consider additional network-level protections to restrict access to the management interface.
