Technical Analysis
The Ebyte NE2-D11 Firmware contains a vulnerability identified as CWE-522, where administrative credentials are stored or transmitted in plaintext within the device's management interface. This flaw allows an attacker with access to the interface to potentially observe or intercept credentials without encryption, compromising device access confidentiality. The CVSS 3.1 vector indicates the attack vector is physical (AV:P), with low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N).
Potential Impact
The primary impact is the exposure of administrative credentials in plaintext, which can lead to unauthorized access if an attacker can observe or intercept these credentials. This compromises the confidentiality of the device's management interface but does not affect integrity or availability.
Mitigation Recommendations
No patch or official fix information is provided for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit physical and network access to the device's management interface to trusted personnel only.
