Detection & IOCs extracted from sources · hover to see the quote

• → The vulnerability resides in the 'Manage Proxies' (Proxy User Delegation) component of Oracle E-Business Suite 12.2, exploitable over HTTP by a self-registered (unauthenticated-at-network-level) user ↗
• → Authentication is technically required but can be bypassed via self-registration; monitor for newly self-registered accounts accessing the Manage Proxies / Proxy User Delegation functionality ↗
• → Oracle E-Business Suite 12.1 is NOT affected; scope detection efforts to 12.2 instances only ↗
• → A nuclei-style HTTP probe checking for a 200 status response on Oracle E-Business Suite endpoints has been associated with this CVE; monitor for automated scanning activity returning HTTP 200 against EBS web interfaces

• · The attack vector is network (HTTP); no local access or elevated privileges are required beyond self-registration, making internet-exposed EBS 12.2 instances the highest-risk targets ↗
