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.



The reported vulnerabilities allow a remote attacker to change the setting, delete the application, set the device to factory defaults, code execution and to cause a system crash or denial of service.

Note(s)

The following products are affected by the listed vulnerabilities:

Series PFC100 (750-81xx/xxx-xxx)
Series PFC200 (750-82xx/xxx-xxx)

The following products are affected by the vulnerability CVE-2019-5078

750-852, 750-831/xxx-xxx, 750-881, 750-880/xxx-xxx, 750-889
750-823, 750-832/xxx-xxx, 750-862, 750-890/xxx-xxx, 750-891

 



If MAC-based port security or 802.1x port security is enabled, the FL NAT 2xxx will unintentionally grant access to unauthorized devices in case of routed transmission.

Subnet 2---(Ports belonging to subnet 2)
|
FL NAT 2xxx
|
(Ports belonging to subnet 1, port sec ON)---- 2nd device
|
-- unauthorized device

The unauthorized device can access other devices in subnet 2 but cannot access the 2nd device in subnet 1



Manipulated PC Worx or Config+ projects could lead to a remote code execution due to
insufficient input data validation.
The attacker needs to get access to an original PC Worx or Config+ project to be able to
manipulate data inside the project folder. After manipulation the attacker needs to exchange the
original files by the manipulated ones on the application programming workstation.



In case TwinCAT is configured to use the Profinet driver, a denial of service of the controller could be reached by sending special packets to the device.



The reported vulnerability allows a remote attacker to check paths and file names that are used in filesystem operations.

Update, 18.9.2019, 18:30

  • fixed typo in modelname, replaced PCF with PFC
