View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to decrypt sensitive data, bypass authentication controls, gaining unauthorized access to read arbitrary files on the system, or gain unauthorized access to protected system resources. The following versions of Johnson Controls Inc. Airwall are affected: Airwall <=4.0.4 (CVE-2026-64887, CVE-2026-34492) CVSS Vendor Equipment Vulnerabilities v3 6.8 Johnson Controls Inc. Johnson Controls Inc. Airwall Use of Hard-coded Cryptographic Key, External Control of File Name or Path Background Critical Infrastructure Sectors: Critical Manufacturing, Commercial Facilities, Government Services and Facilities, Transportation Systems, Energy Countries/Areas Deployed: Worldwide Company Headquarters Location: Ireland Vulnerabilities Expand All + CVE-2026-64887 A hardcoded password or cryptographic key was identified in the Airwall application. A hardcoded credential leads to a significant authentication failure that can be difficult for system or application administrators to detect. Once discovered, it is difficult to remediate without manually modifying or patching the software. The hardcoded key is identical across all installations of the product and across all customer organizations, meaning a single disclosure of the key - common on the internet - grants any knowledgeable attacker access to all affected deployments. An attacker with access to application code or binary files can use the hardcoded key to decrypt sensitive application data stored in configuration and database files, enabling further data disclosure or compromise of application infrastructure. View CVE Details Affected Products Johnson Controls Inc. Airwall Vendor: Johnson Controls Inc. Product Version: Johnson Controls Inc. Airwall: <=4.0.4 Product Status: known_affected Remediations Mitigation To help reduce risk of exploitation, Johnson Controls recommends the following defensive measures: Apply v4.1.0 or later patches for all Airwalls. Mitigation Store all cryptographic keys in a secure key management system (KMS) or hardware security module (HSM) rather than embedding them in source code or configuration files. (CVE-2026-64887) Mitigation Implement a regular key rotation policy to limit the exposure window if a key is compromised. (CVE-2026-64887) Mitigation Use unique cryptographic keys per device, installation, or deployment instance to prevent a single compromised key from affecting all installations. (CVE-2026-64887) Mitigation Remove any hard-coded keys from source code repositories and binaries, replacing them with references to secure external key stores. (CVE-2026-64887)Apply the principle of least privilege to key access, ensuring only authorized processes and personnel can retrieve cryptographic material. (CVE-2026-64887) Mitigation Use static analysis and secrets-scanning tools in CI/CD pipelines to detect and prevent hard-coded keys from being committed to source control. (CVE-2026-64887) Mitigation Encrypt keys at rest and in transit and ensure key-wrapping mechanisms are in place for any keys stored on disk. (CVE-2026-64887) Mitigation Audit and monitor access to cryptographic keys, logging all retrieval and usage events for anomaly detection. (CVE-2026-64887) Mitigation Refer to and follow all steps in the product hardening guide or the JCI universal hardening guide found here https://www.johnsoncontrols.com/trust-center/cybersecurity/resources (CVE-2026-64887) https://www.johnsoncontrols.com/trust-center/cybersecurity/resources Mitigation For more detailed mitigation instructions, please see Johnson Controls Product Security Advisory JCI-PSA-2026-25 at the following location: https://www.johnsoncontrols.com/trust-center/cybersecurity/security-advisories (CVE-2026-64887) https://www.johnsoncontrols.com/trust-center/cybersecurity/security-advisories Relevant CWE: CWE-321 Use of Hard-coded Cryptographic Key Metrics CVSS Version Base Score Base Severity Vector String 3
