Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior are vulnerable to a use of hard-coded credential vulnerability. This could allow an attacker to intercept sensitive information or credentials.
AnalysisAI
Hard-coded credentials in Tycon Systems TPDIN-Monitor-WEB3 firmware versions 2.2.9 and prior expose the device to unauthorized access from network-adjacent attackers. An attacker with access to the same network segment can leverage the embedded credentials - extractable from the firmware binary - to authenticate to the device and retrieve sensitive configuration data, credentials, or monitoring telemetry. …
