View CSAF Summary Successful exploitation of this vulnerability could result in an attacker obtaining confidential information from the device. The following versions of Johnson Controls XAAP Android are affected: XAAP Android <1.53 CVSS Vendor Equipment Vulnerabilities v3 3.3 Johnson Controls Johnson Controls XAAP Android Cleartext Storage of Sensitive Information Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Ireland Vulnerabilities Expand All + CVE-2026-34490 A cleartext storage weakness exists in the Fire Solutions Android application, which stores application data locally on the device without encryption. An attacker with physical access to the device and one able to compromise the device through a separate, unrelated flaw, could potentially read this data in plaintext. Exploitation does not require network access and is limited to the local device environment. View CVE Details Affected Products Johnson Controls XAAP Android Vendor: Johnson Controls Product Version: Johnson Controls XAAP Android: <1.53 Product Status: known_affected Remediations Vendor fix Johnson Controls recommends users update the XAAP Android application to version 1.53 or later, which contains the fix for this vulnerability. Mitigation Johnson Controls recommends users restrict physical access to devices running the XAAP Android application. Mitigation Johnson Controls recommends users ensure devices are hardened with up-to-date Android OS versions, device encryption enabled, and screen lock protections in place. Mitigation Johnson Controls recommends users implement a Mobile Device Management (MDM) solution to enforce security policies, including encryption requirements, application whitelisting, and remote wipe capabilities. Mitigation Johnson Controls recommends users Avoid rooting or jailbreaking devices used in production environments, as this weakens OS-level security controls that help protect local application data.

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. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
