Technical details

This vulnerability is classified as a missing authentication for a critical function (CWE-306) within the WebCenter Sites component of Oracle Fusion Middleware. It is remotely exploitable via HTTP without authentication, requiring low complexity and no user interaction. The flaw is particularly severe because it involves a 'scope change' (S:C), meaning a successful exploit can allow an attacker to move beyond the WebCenter Sites environment to impact other integrated products or the underlying infrastructure. Successful exploitation results in a complete takeover of the affected instance. Affected versions include 12.2.1.4.0 and 14.1.2.0.0.
