Summary
AWIN Gateways Vulnerabilities in Embedded Webserver

Notes

Summary
ABB became aware of vulnerability in the products versions listed as affected in the advisory. An update is available that resolves the reported vulnerabilities. AWIN gateways are not intended to be internet-facing. An attacker who successfully exploited this vulnerability could take remote control of the product and reboot the device, potentially causing a denial of service. It can also reveal system specific configuration. ABB requires, as noted in the User Manual, that AWIN gateways should not be exposed to the internet or any other insecure network. Note. To exploit this vulnerability the attacker needs access to the AWIN gateways. These gateways are installed on sites which often have perimeter security, and the gateways are installed behind firewalls.
Support

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. - Never connect programming software or computers containing programing software to any network other than the network for the devices that it is intended for. - Scan all data imported into your environment before use to detect potential malware infections. - 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 anti-virus and firewall. - When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices. More information on recommended practices can be found in the documents listed in the References section.
Purpose
ABB has a rigorous internal cyber security continuous improvement process which involves regular testing with industry leading tools and periodic assessments to identify potential product issues. Occasionally an issue is determined to be a design or coding flaw with implications that may impact product cyber security. When a potential product vulnerability is identified or reported, ABB immediately initiates our vulnerability handling process. This entails validating if the issue is in fact a product issue, identifying root causes, determining what related products may be impacted, developing a remediation, and notifying end users and governmental organizations. The resulting Cyber Security Advisory intends to notify customers of the vulnerability and provide details on which products are impacted, how to mitigate the vulnerability or explain workarounds that minimize the potential risk as much as possible. The release of a Cyber Security Advisory should not be misconstrued as an affirmation or indication of an active threat or ongoing campaign targeting the products mentioned here. If ABB is aware of any specific threats, it will be clearly mentioned in the communication. The publication of this Cyber Security Advisory is an example of ABB’s commitment to the user community in support of this critical topic. Responsible disclosure is an important element in the chain of trust we work to maintain with our many customers. The release of an Advisory provides timely information which is essential to help ensure our customers are fully informed.
Frequently Asked Questions
What causes vulnerability? - Authentication Bypass due to Improper Session Validation. What are AWIN Gateways? - They are WirelessHART gateways. They are intended to be located between level 0 (process) and level 1 (basic control) hierarchy of the IEC 62443 reference model. They collect sensor data and provide this information to the host systems. What might an attacker use the vulnerability to do? - An attacker who successfully exploited this vulnerability can render the WirelessHART network unavailable. How could an attacker exploit the vulnerability? - An attacker will have to first connect to the same local network where the gateway is present. This vulnerability can be exploited by sending a crafted HTTP GET request using a previously observed or valid time parameter value, regardless of the password used during the initial login attempt. Could the vulnerability be exploited remotely? - No. Remote access is disabled in the gateways. Can functional safety be affected by an exploit of this vulnerability? - This product is not intended to be used in functional safety applications. What does the update do? - It enforces HTTPS access. Unauthenticated requests are explicitly denied. Configuration data is not exposed anymore. When this security advisory was issued, had this vulnerability been publicly disclosed? - No, ABB received information about this vulnerability through responsible disclosure. When this security advisory was issued, had ABB received any reports that this vulnerability was being exploited? - No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued.
