• → CVE-2020-2852 affects Oracle Advanced Outbound Telephony (Calendar component) in Oracle E-Business Suite versions 12.1.1 through 12.1.3, exploitable remotely via HTTP without authentication, requiring user interaction — monitor for anomalous unauthenticated HTTP requests targeting the Calendar component of Oracle AOT. ↗
