CVE-2018-3147 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 are 8.5.3 and 8.5.4. 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 read access to a subset of Oracle Outside In Technology accessible data. 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 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).

The vulnerability identified as CVE-2018-3147 resides within Oracle Outside In Technology, a critical component of Oracle Fusion Middleware that functions as a suite of software development kits enabling applications to process various file formats. This specific flaw manifests in the Outside In Filters subcomponent and affects versions 8.5.3 and 8.5.4 of the Oracle Fusion Middleware platform. The vulnerability operates at the intersection of network protocol handling and file processing capabilities, creating a potential entry point for malicious actors seeking to access sensitive data within systems utilizing this technology. The security implications extend beyond simple network access as the vulnerability specifically targets the processing of external data through the Outside In Technology SDKs, making it particularly dangerous in enterprise environments where document processing is commonplace.
The technical exploitation of this vulnerability requires an attacker to leverage HTTP network access to interact with Oracle Outside In Technology components without authentication. This represents a network-based attack vector that can be executed remotely, though it necessitates human interaction from users who are not the attackers themselves. The attack mechanism operates through the processing of data that flows through the Outside In Technology code, where the vulnerability allows unauthorized read access to a subset of accessible data within the technology's scope. This particular flaw aligns with CWE-200, which addresses "Information Exposure," and demonstrates the classic pattern of information disclosure vulnerabilities that can be exploited through improper input validation or insufficient access controls. The CVSS 3.0 scoring system rates this vulnerability at 4.3, indicating a moderate severity level with specific emphasis on confidentiality impacts, though the actual risk can vary significantly based on how the underlying software integrates with Outside In Technology code.
The operational impact of CVE-2018-3147 extends beyond simple data exposure to potentially compromise entire document processing workflows within Oracle Fusion Middleware environments. Attackers who successfully exploit this vulnerability can gain access to sensitive information that would normally be restricted, though the scope is limited to a subset of accessible data rather than complete system compromise. This limitation in the attack scope makes the vulnerability less severe than some other exploits but still represents a significant risk for organizations processing confidential documents or data through systems utilizing Outside In Technology. The vulnerability's classification under the ATT&CK framework would align with techniques involving information gathering and credential access, as it enables unauthorized data reconnaissance and potential exfiltration. Organizations implementing this technology must consider the broader implications for their document management systems, as the vulnerability could enable attackers to access sensitive business documents, personal information, or proprietary data that flows through these processing pipelines.
Mitigation strategies for CVE-2018-3147 should focus on implementing proper access controls and network segmentation to limit exposure of Oracle Outside In Technology components to untrusted networks. Organizations should ensure that affected versions 8.5.3 and 8.5.4 are updated to patched releases from Oracle, as these versions contain the necessary security fixes to address the vulnerability. Network-level protections including firewalls and intrusion detection systems should be configured to monitor and restrict HTTP traffic to systems utilizing Outside In Technology, particularly in environments where this technology processes sensitive data. Additionally, administrators should implement proper input validation and sanitization practices when integrating Outside In Technology code into applications, ensuring that data processing flows do not inadvertently expose system resources to unauthorized access. The vulnerability's requirement for human interaction suggests that user education and awareness programs should be implemented to prevent accidental exploitation through social engineering or other human factors that could enable attackers to leverage this vulnerability effectively.
