CVE-2018-12923

Vulnerability

BWS Systems HA-Bridge, a bridge application for IoT devices, does not require authentication for access to the #!/system URI. This allows any remote attacker to directly request that URI and obtain potentially sensitive information. Affected versions were current as of June 2018; no specific version numbers were disclosed in the available references [1].

Exploitation

An attacker needs only network access to the HA-Bridge device. No authentication, user interaction, or special privileges are required. By sending a direct HTTP request to the #!/system URI, the attacker can retrieve the sensitive data without any further steps [1].

Impact

Successful exploitation results in information disclosure of potentially sensitive data related to the IoT bridge configuration. The leaked data may include credentials, device details, or other internal parameters, which could be used to further compromise the IoT environment or gain unauthorized access [1].

Mitigation

As of the publication date, no official fix or workaround was made available in the references. Users should implement network access controls, such as firewalls or VPNs, to restrict access to the HA-Bridge management interface to trusted hosts only, until a patch is released [1].
