Rockwell Automation Verve Asset Manager

Verve Asset Manager versions prior to 1.38 contain an access control vulnerability (CWE-842) that allows an authenticated administrator user to view or access data objects that should be restricted by permission mappings. If an administrator's access is reduced or revoked through policy changes, the application fails to properly enforce the new restrictions, allowing retrieval of previously-accessible data. Rockwell Automation has released version 1.38 with a fix. As a workaround, administrators can manually remove and rebuild all user permission mappings to ensure current policy is enforced.

Rockwell Automation has addressed this issue in version 1.38 and encourages users to update to the newest available version. Rockwell Automation encourages users of the affected software to apply risk mitigations, if possible. Additionally, they encourage users to implement suggested security best practices to minimize the risk of vulnerability: The presence of any mappings will help prevent this vulnerability from being exploited. If all mappings must be removed, manually removing previously mapped users is an effective workaround. Security Best Practices For more information about this issue, please see the advisory on the Rockwell Automation security page. CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating 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 current version available. Also recognize VPN is only as secure as the 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/ics. 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/ics 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. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages.
