## Technical details

HCL AION fails to enforce encryption for specific data transmissions or operations, a vulnerability classified as CWE-319 (Cleartext Transmission of Sensitive Information). The attack vector is restricted to the adjacent network (AV:A) and requires high complexity (AC:H) along with user interaction (UI:R). An attacker positioned on the same local network could potentially intercept unencrypted traffic to capture sensitive data or perform unauthorized operations. HCL has released a security bulletin (KB0130636) addressing this and other vulnerabilities in the AION product.
