Atomicorp WAF Research Note: CVE-2018-3238

Oracle Fusion Middleware WebCenter Sites 11.1.1.8.0 - Cross-Site Scripting

Research Notes

This page documents research related to exploit techniques, attack behaviors, testing results, and WAF rule interactions associated with this vulnerability.

Research finding: this note documents observed WAF protections relevant to exploit techniques associated with this vulnerability.

These notes are not intended to represent the full set of vulnerabilities mitigated by Atomicorp products and should not be interpreted as a coverage matrix, certification list, or census of protected CVEs.

Atomicorp WAF protections are primarily designed around attack techniques and exploit behaviors rather than individual vulnerability identifiers. A published research note documents a positive research finding related to that CVE. If a CVE is absent from these notes, no conclusion should be drawn about protection status.

Vulnerability Description

Vulnerability in the Oracle WebCenter Sites component of Oracle Fusion Middleware (subcomponent: Advanced UI). The supported version that is affected is 11.1.1.8.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle WebCenter Sites. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Sites, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Sites accessible data as well as unauthorized update, insert or delete access to some of Oracle WebCenter Sites accessible data. CVSS 3.0 Base Score 6.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N).
