Phoenix Contact Emalytics Controller ILC 2050 BI are developed and designed for the use in protected building automation networks.
An issue was discovered on Phoenix Contact Emalytics Controller ILC 2050 BI before 1.2.3 and BI-L before 1.2.3 devices. There is an insecure mechanism for read and write access to the configuration of the device. The mechanism can be discovered by examining a link on the website of the device.
If the above-mentioned controllers are used in an unprotected, open network, an unauthorized attacker can change the device configuration and start or stop services.
Phoenix Contact strongly recommends affected users to update to Engineering software Emalytics 1.2.3 or higher and recommission the controllers.
