CVE-2018-3238: Vulnerability in the Oracle WebCenter Sites component of Oracle Fusion Middleware (subcomponent: Advanced UI)

Recommended actionScheduled

Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.

Patch available

What, why and how

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).

What

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

What

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path: a network path → vulnerable operation → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface: Network
Privileges required: High: elevated access is required
User interaction: Required interaction required
Attack complexity: Low: no specialised conditions are recorded
Security boundary: Changed: exploitation can affect a different security authority
