Privileged authentication abuse on adjacent networks
Published Oct 1, 2026 · Updated Oct 1, 2026
Insecure default initialization in Johnson Controls EasyIO FS-32 before 3.0b63 allows attackers with elevated access to abuse authentication. The Johnson Controls CNA does not identify the resource or initialization step responsible; the vendor separately documents a passwordless default CPT admin login but does not link it to this CVE. The published assessment requires adjacent-network access and high privileges, while the resulting authentication abuse remains unspecified.
