CVE-2019-2613 in Outside In Technology
Summary
by MITRE
Vulnerability in the Oracle Outside In Technology component of Oracle Fusion Middleware (subcomponent: Outside In Filters). Supported versions that are 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 of this vulnerability can result in unauthorized read access to a subset of 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 6.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L).

The vulnerability identified as CVE-2019-2613 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 and convert various document formats. This specific flaw exists within the Outside In Filters subcomponent and affects versions 8.5.3 and 8.5.4 of the Oracle Fusion Middleware platform. The vulnerability represents a significant security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, making it particularly dangerous in enterprise environments where such middleware components are extensively deployed. The affected Outside In Technology SDKs are commonly integrated into business applications that handle document processing, making this vulnerability particularly concerning for organizations relying on document management systems.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Outside In Filters processing engine. Attackers can exploit this weakness by sending specially crafted HTTP requests that bypass normal authentication procedures and directly interact with the vulnerable component. The flaw allows for unauthorized read access to sensitive data within the affected Oracle Outside In Technology environment, potentially exposing confidential information processed through these SDKs. Additionally, successful exploitation can result in partial denial of service conditions that impact the availability of the affected system, disrupting business operations and potentially causing cascading failures in document processing workflows. This vulnerability operates at the application layer and can be classified under CWE-20 as "Improper Input Validation" and CWE-284 as "Improper Access Control," representing fundamental security design flaws that enable unauthorized access to system resources.
The operational impact of CVE-2019-2613 extends beyond simple data exposure to encompass broader business continuity concerns. Organizations utilizing Oracle Fusion Middleware with affected versions face potential data breaches where confidential documents or information processed through the Outside In Technology SDKs could be accessed by unauthorized parties. The partial denial of service component of this vulnerability can disrupt critical business processes that depend on document conversion and processing capabilities, particularly affecting applications such as content management systems, document repositories, and enterprise resource planning platforms. The CVSS score of 6.5 reflects the moderate to high severity of this vulnerability, indicating that while exploitation requires network access, the potential damage can be substantial. The vulnerability's classification under the ATT&CK framework would align with techniques such as T1190 "Exploit Public-Facing Application" and T1068 "Exploitation for Privilege Escalation," though the specific impact here relates to data exposure rather than privilege escalation.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates specifically designed to address this vulnerability. Network segmentation and firewall rules should be configured to restrict unnecessary HTTP access to Oracle Fusion Middleware components, particularly those utilizing Outside In Technology. Access controls should be strengthened through proper authentication mechanisms and privilege management to limit exposure even if the vulnerability is exploited. Monitoring and logging should be enhanced to detect suspicious HTTP requests targeting the vulnerable components, with particular attention to unusual patterns in document processing requests. The CVSS vector analysis indicates that if the software properly validates input before passing it to Outside In Technology code, the effective risk may be reduced, but organizations should not rely solely on this protection mechanism. Regular security assessments and vulnerability scanning should be conducted to identify any other potentially affected systems within the enterprise environment that might utilize the same vulnerable SDKs.
