SICK FTMg AIR FLOW SENSORS are used to measure airflow in industrial applications. Unfortunately, a vulnerability has been discovered that could allow unauthorized access to sensor data.

The vulnerability (CVE-2023-23445) is an improper access control issue in the REST interface of certain SICK FTMg AIR FLOW SENSOR models. By using an unprivileged account, a remote attacker could potentially gain access to restricted data fields.

This occurs because authentication checks are not stringent enough. An attacker who obtains valid login credentials, even for a limited account, may be able to access more privileged information than they should have rights to see.

The risk level is considered high at 7.5 out of 10 on the CVSS vulnerability scoring system. A malicious actor taking advantage could steal confidential airflow readings or sensor configurations. This could disrupt industrial processes or even potentially damage equipment if settings are changed without authorization.

The best way to protect yourself is to make sure your SICK FTMg AIR FLOW SENSORS are updated to the latest firmware version, which should resolve this vulnerability. You should also use strong and unique credentials for sensor access, change default passwords, and carefully restrict account privileges to only necessary data views. Staying on top of patches and secure configuration practices can help prevent unauthorized data access.
