Technical details
HCL AION is vulnerable to CWE-319 (Cleartext Transmission of Sensitive Information) because it may transmit backend service details over insecure HTTP channels. The vulnerability requires an attacker to be on an adjacent network (AV:A) and involves high complexity (AC:H), requiring specific conditions and potentially user interaction (UI:R) to successfully intercept the data. If exploited, an attacker can capture sensitive information during transmission, which could facilitate further attacks against the backend infrastructure. Users are advised to refer to HCL Software's security bulletin KB0130636 for remediation steps.
