    CVE-2026-6411

    This vulnerability, in the MAXHUB Pivot client application versions prior to v1.36.2, may allow an attacker to obtain encrypted tenant email addresses and related metadata from any tenant. Due to the presence of a hardcoded AES key within the application, the encrypted data can be decrypted, enabling access to tenant email addresses and associated information in cleartext. Furthermore, an attacker may be able to cause a denial-of-service condition by enrolling multiple unauthorized devices into a tenant via MQTT, potentially disrupting tenant operations.

    Recommended Practices
    CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. 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.
