Mitigating factors
The path traversal vulnerability is only exploitable when the attacker has local access to the machine hosting the web application (i.e., access to localhost). To mitigate this vulnerability, the affected products should be configured to restrict local access to authorized users only, ensuring that untrusted users cannot interact with the application directly on the host system. ABB has restricted file downloads to a specific directory designated solely for downloadable content. Strict input validation and path sanitization are implemented to ensure that only legitimate file paths within this directory can be accessed. Refer to section “General Security Recommendations” for further advise on how to keep your system secure.
Frequently Asked Questions
What causes the vulnerability? The vulnerability is caused by unchecked input data in the file parameter in the CoreSense products. What might an attacker use the vulnerability to do? An attacker who successfully exploited this vulnerability can allow unauthenticated users to gain access to restricted directories and can lead to complete system compromise and exposure of sensitive information. How could an attacker exploit the vulnerability? Path traversal would require that the attacker has access to the system local network, by connecting to the system directly or through a wrongly configured or penetrated firewall, or that he installs malicious software on a system node or otherwise infects the network with malicious software. Recommended practices help mitigate such attacks, see mitigating factors section. Could the vulnerability be exploited remotely? No. Can functional safety be affected by an exploit of this vulnerability? No. What does the update do? The update removes the vulnerability by modifying the way that the file parameter validates and verifies input data. 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.

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate them from business networks. When remote access is required, use more secure methods, such as virtual private networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
