Summary
Low Voltage DC Drives and Power Controllers CODESYS RTS Vulnerabilities

Notes

Summary
CODESYS group published several vulnerabilities regarding the CODESYS Runtime System, which is included in the firmware of ABB LV DC drives and power controllers. It is used to implement a selection of features and to provide IEC 611131-3 programming capabilities. These vulnerabilities include memory corruption issues that could lead to out-of-bound memory access. Subsequently, a successful exploit could allow attackers to trigger a denial-of-service condition or execute arbitrary code over the fieldbus interfaces. Exploiting these vulnerabilities requires an IEC 61131-3 license being present on the memory unit of the drive or power controller.
Mitigating factors
The vulnerabilities only pose a threat if an IEC 61131-3 license is provisioned to the memory unit. The exploitation can be triggered via USB on the panel or via fieldbus or Ethernet using a fieldbus connector. If none of these are connected exploitation is not possible. For network based attacks the attacker needs to be able to reach the drive or power controller via the network.
General security recommendations
For any installation of software-related ABB products we strongly recommend the following (non-exhaustive) list of cyber security practices: – Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls and separate them from any general-purpose network (e.g. office or home networks). – Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks. – Minimize network exposure for all applications and endpoints to ensure that they are not accessible from the Internet unless they are designed for such exposure and the intended use requires such. – Ensure all nodes are always up to date in terms of installed software, operating system, and firmware patches as well as antivirus and firewall. – When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Also, understand that VPNs are only as secure as the connected devices.
Workarounds
ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as Impact of workaround. Activate User Lock and disable file upload To mitigate the exploitability of the vulnerabilities ABB recommends disabling the upload of firmware, including IEC 61131-3 programs to the drive or power controller. Additionally, it is recommended to close the User Lock and enable the Parameter Lock, so an attacker is not able to unblock the firmware upload over fieldbus. The settings can be applied via the Drive Composer tool. For the user lock to be effective and the parameter lock bound to the user lock, the following steps need to be performed: DCS880 • Enter the default user pass code 10000000 in 96.07 Pass code • Change the default user pass code to a random number using 96.100 Change user pass code and 96.101 Confirm user pass code • In 96.102 User lock functionality set bits 0, 2, 3 and 6 to 1 (high) • Bit 0: Disable ABB access levels • Bit 2: Disable file download • Bit 3: Disable Fieldbus write to hidden parameters • Bit 6: Protect AP • Enter any invalid pass code in 96.07 Pass code to close the lock • To enable the parameter lock set 96.07 Pass code = 358 • In 96.04 Access Levels Active Bit 14 (parameter lock) is set • Enter your user pass code in 96.07 Pass code to open the lock • In 96.102 User lock functionality set bit 1 to 1 (high) to freeze the parameter lock state • Enter any invalid pass code in 96.07 Pass code to close the lock DCT880 • Enter the default user pass code 10000000 in 96.02 Pass code • Change the default user pass code to a random number using 96.100 Change user pass code and 96.101 Confirm user pass code • In 96.102 User lock functionality set bits 0, 2, 3 and 6 to 1 (high) • Bit 0: Disable ABB access levels • Bit 2: Disable file download • Bit 3: Disable Fieldbus write to hidden parameters • Bit 6: Protect AP • Enter any invalid pass code in 96.02 Pass code to close the lock • To enable the parameter lock set 96.02 Pass code = 358 • In 96.03 Access Levels Active Bit 14 (parameter lock) is set • Enter your user pass code in 96.02 Pass code to open the lock • In 96.102 User lock functionality set bit 1 to 1 (high) to freeze the parameter lock state • Enter any invalid pass code in 96.02 Pass code to close the lock Verification Please be aware: If those steps are not performed in the correct order, the pass code might be circum-vented. Setting the correct User Lock Functionality bits is not enough to secure the device. Please make sure the lock is closed (parameters 96.100 to 96.102 not visible). If the User Lock is open, warning 1236 is set. Impact of the workaround After applying the workaround, the IEC 61131-3 programs can be used, but not uploaded to the drive anymore. To upload an IEC program the operator has to unlock the User Lock and disable the File Up-load Lock. If the parameter lock is applied no parameter of the drive can be changed. To change the parameter the operator has to unlock the User Lock and disable the parameter lock. The disablement of the file downloads includes • Firmware uploads • Safety functions module FSO-21 configuration • Parameter restore to default values. See parameter 96.15 for details. • Loading of adaptive programs • Loading and debugging application programs via Drive application builder • Changing the home view of the control panel • Editing drive texts • Editing the favorite parameters list on the control panel • Configuration settings done via control panel (time, date, etc.) It is strongly recommended to only unlock the User Lock in a maintenance scenario, not during normal operation. Enabling upload of files and therefore an update of firmware during operation could lead to undesired behavior. As long as the User Lock is open the vulnerabilities are exploitable.
