CVE-2018-3092 in Outside In Technology
Summary
by MITRE
Vulnerability in the Oracle Outside In Technology component of Oracle Fusion Middleware (subcomponent: Outside In Filters). The supported version that is affected is 8.5.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Outside In Technology. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Outside In Technology accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Outside In Technology. Note: Outside In Technology is a suite of software development kits (SDKs). The protocol and CVSS score depend on the software that uses the Outside In Technology code. The CVSS score assumes that the software passes data received over a network directly to Outside In Technology code, but if data is not received over a network the CVSS score may be lower. CVSS 3.0 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L).

The vulnerability identified as CVE-2018-3092 resides within Oracle Outside In Technology, a comprehensive suite of software development kits that enable applications to process and convert various document formats. This particular flaw exists in the Outside In Filters subcomponent of Oracle Fusion Middleware, specifically affecting version 8.5.3 which represents a supported release. The vulnerability manifests as an easily exploitable security weakness that can be leveraged by unauthenticated attackers who gain network access through HTTP protocols. The security implications are significant as this flaw creates potential pathways for unauthorized access to sensitive data and complete control over all accessible data within the Oracle Outside In Technology environment.
The technical nature of this vulnerability stems from insufficient input validation within the Outside In Filters processing mechanisms, creating opportunities for attackers to craft malicious payloads that can be processed by the vulnerable component. This flaw operates under the Common Weakness Enumeration framework as a weakness related to insufficient input validation and potentially buffer overflows or injection vulnerabilities. The attack vector requires network connectivity via HTTP protocols and can be executed without authentication, making it particularly dangerous for systems that expose this functionality to external networks. The vulnerability's exploitability is classified as low complexity due to the minimal prerequisites required for successful exploitation, while the attack requires human interaction from an unsuspecting user who must interact with the malicious content, often through web-based interfaces or document processing workflows.
The operational impact of CVE-2018-3092 extends beyond simple data compromise to include potential complete system access and partial denial of service conditions. Attackers who successfully exploit this vulnerability can gain unauthorized access to critical data repositories and potentially cause service disruption that affects the availability of the Outside In Technology functionality. The CVSS 3.0 score of 7.1 reflects the high confidentiality impact of 8.1 and the availability impact of 5.9, indicating that this vulnerability can result in significant data exposure while also creating partial service disruption scenarios. The vulnerability's severity is particularly concerning because it affects the underlying processing libraries that numerous applications depend upon, potentially creating cascading effects across multiple systems that utilize Oracle Fusion Middleware components. The vulnerability's impact is further amplified by the fact that Outside In Technology is widely used across enterprise environments for document processing, making successful exploitation potentially devastating for organizations that rely on these capabilities.
Organizations should implement immediate mitigations including network segmentation to isolate vulnerable systems, disabling unnecessary HTTP access to Outside In Technology components, and applying Oracle's security patches as soon as they become available. The ATT&CK framework categorizes this vulnerability under the T1190 technique for Exploit Public-Facing Application, highlighting the need for organizations to maintain robust application security controls and regular vulnerability assessments. Additional protective measures should include implementing web application firewalls to monitor and filter malicious HTTP requests, conducting regular security audits of exposed services, and establishing network monitoring to detect anomalous access patterns that may indicate exploitation attempts. The vulnerability's classification as a network-based attack emphasizes the importance of maintaining up-to-date network security controls and ensuring that only necessary services are exposed to external networks, particularly in environments where document processing capabilities are essential but must remain protected from unauthorized access.
