CVE-2026-80276: CWE-306 Missing Authentication for Critical Function in Comelit Group S.p.A. 1456B Multi-User Gateway
Comelit Multi-User Gateway for VIP System (model 1456B) firmware versions 2.9.1 and 2.10.0 expose a network-accessible management interface that does not require authentication. Through this interface, sensitive device configuration data - including the Remote Configuration Password - can be read in cleartext by a remote, unauthenticated attacker.
AI Analysis
Technical Summary
The Comelit 1456B Multi-User Gateway firmware versions 2.9.1 and 2.10.0 expose a management interface over the network that lacks authentication controls. This missing authentication (CWE-306) enables unauthenticated remote attackers to access sensitive configuration information, such as the Remote Configuration Password, in cleartext. The vulnerability has a CVSS 3.1 base score of 7.5, indicating high severity due to network attack vector, no privileges required, no user interaction, and high confidentiality impact.
Potential Impact
An unauthenticated remote attacker can access sensitive configuration data including the Remote Configuration Password in cleartext. This exposure compromises confidentiality and could lead to further unauthorized access or manipulation of the device or connected systems. There is no indication of impact on integrity or availability.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the management interface to trusted networks only to mitigate exposure.
