CVE-2026-1364Network attack vector

Administrative control via missing authentication checks

Published Jan 23, 2026 · Updated Jan 23, 2026

Missing authentication in JNC IAQS and I6 version 0 allows remote attackers to operate system administrative functions without credentials. TWCERT/CC has not published the affected administrative endpoints or the precise code path that omits authentication checks. Network access to the appliances is sufficient, and successful exploitation grants direct control over administrative operations that can alter monitoring and control behavior.
