Summary
Vulnerable components expose sensitive information to unauthorized actors through an unsecured configuration interface. Vulnerable firmware releases contain an unsecured configuration interface that allows retrieval of sensitive information such as hashed credentials.
It was found that users with no or low rights can access information from devices that should not be available to them.
An attacker can use this information to impersonate authorized users.
Impact
An authenticated attacker can obtain sensitive information, potentially enabling authenticated device modification.

Vulnerabilities
Expand / Collapse allAn unsecured configuration interface on the affected devices allows an authenticated attacker with adjacent access (with Bluetooth) to gain sensitive information like hashed credentials and access codes.
Mitigation
Implement access controls for interfaces to prevent unauthorized access.
Remediation
Update to the fixed firmware versions listed in this advisory. Rotate any credentials used on affected devices as they may have been compromised. Contact VEGA Support if emergency code rotation is necessary based on your risk assessment.
