Description
Vulnerability in the Oracle Outside In Technology product of Oracle Fusion Middleware (component: Outside In Clean Content SDK). The supported version that is affected is 8.5.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Outside In Technology. While the vulnerability is in Oracle Outside In Technology, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Outside In Technology accessible data. CVSS 3.1 Base Score 8.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

AI Analysis

Impact

This vulnerability is a flash point that allows an adversary who can reach the Oracle Outside In Technology services over HTTP without authentication to obtain full access to any data that the service can read. Because the flaw is in the Clean Content SDK component, the attacker can bypass normal authorization, meaning that confidential or critical information could be disclosed or manipulated. The weakness leads to a loss of confidentiality and potential data integrity compromise for systems that rely on this library.

Affected Systems

Oracle Outside In Technology version 8.5.8 is impacted. The problem resides in the Outside In Clean Content SDK component of Oracle Fusion Middleware. Any deployment of this version that exposes the service to the network is susceptible; related products may also be affected through a scope change.

Risk and Exploitability

The CVSS v3.1 base score of 8.6 indicates a high–severity vulnerability with network–level attack vector, no authentication, and a single user impact dominated by confidentiality. The EPSS score of 0.4% indicates a very low, but nonzero probability of exploitation, and the vulnerability is not yet listed in the CISA KEV catalog. Nevertheless, the description states it is "easily exploitable" by unauthenticated HTTP traffic, so the chance of successful attacks in environments where the component is exposed is significant. The scope change suggests that other Oracle Fusion Middleware components could be compromised if not isolated.
