criticalCVE-2026-64887CVE-2026-34492
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.
