CVE-2026-64887: CWE-321 Use of hard-coded cryptographic key in Johnson Controls Airwall
Use of hard-coded cryptographic key vulnerability in Johnson Controls Airwall allows : Cryptanalytic Attack. This issue affects Airwall: before 4.1.
AI Analysis
Technical Summary
CVE-2026-64887 is a vulnerability in Johnson Controls Airwall where a hard-coded cryptographic key is used. This cryptographic weakness can enable attackers to perform cryptanalytic attacks against the affected software. The issue affects Airwall versions prior to 4.1. The vulnerability has been assigned a CVSS 4.0 score of 7.0, indicating high severity. There is currently no vendor advisory or patch available, and no known exploits in the wild have been reported.
Potential Impact
The use of a hard-coded cryptographic key undermines the confidentiality and integrity of cryptographic operations within Johnson Controls Airwall. This weakness can allow attackers to perform cryptanalytic attacks, potentially leading to unauthorized data decryption or manipulation. However, there is no evidence of active exploitation at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should monitor vendor communications for updates and consider limiting exposure of affected Airwall instances where feasible.
