CVE-2019-2756 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 8.5.4. 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 update, insert or delete access to some of Oracle Outside In Technology accessible data as well as 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 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

The vulnerability identified as CVE-2019-2756 resides within Oracle Outside In Technology, a comprehensive suite of software development kits that provides document processing capabilities across various platforms and applications. This component serves as a foundational element within Oracle Fusion Middleware, specifically within the Outside In Filters subcomponent, where it handles the parsing and processing of various document formats. The affected version 8.5.4 represents a critical security gap that exposes organizations relying on this technology to significant operational risks. The vulnerability manifests as a flaw in how the system processes incoming HTTP requests, creating an attack surface that can be exploited by unauthenticated network adversaries without requiring any prior authentication credentials or privileged access.
This security weakness operates as an easily exploitable vulnerability that allows attackers to compromise the Oracle Outside In Technology through unauthenticated network access via HTTP protocols. The technical implementation flaw enables attackers to perform unauthorized operations including updates, inserts, and deletions of data within the accessible scope of the technology, while simultaneously gaining unauthorized read access to sensitive data subsets. Additionally, the vulnerability permits attackers to induce partial denial of service conditions that can disrupt normal operational functionality of the affected systems. The CVSS score of 7.3 reflects the severity of impacts across confidentiality, integrity, and availability domains, with the vector configuration indicating network-based attack accessibility with low complexity requirements and no privilege requirements.
The operational impact of this vulnerability extends beyond simple data compromise, as it affects the fundamental integrity of document processing systems that organizations depend upon for business operations. Organizations utilizing Oracle Fusion Middleware with Outside In Technology components face potential data leakage scenarios where sensitive information can be accessed or modified without detection, while the partial denial of service capability can disrupt critical business processes that rely on document processing capabilities. The vulnerability's characteristics align with CWE-20, representing input validation flaws, and can be mapped to ATT&CK technique T1190 for exploiting vulnerabilities in software applications. The attack vector specifically targets the network protocol handling within the Outside In Technology SDK, where the system fails to properly validate or sanitize incoming data streams before processing them through the document parsing engine.
Mitigation strategies should focus on immediate patch deployment for the affected Oracle Outside In Technology version 8.5.4, while implementing network-level controls to restrict access to affected systems. Organizations should consider network segmentation and firewall rules to limit HTTP access to only trusted sources, along with implementing robust monitoring and logging mechanisms to detect anomalous access patterns. The vulnerability's classification as a medium severity issue within the CVSS framework indicates that while exploitation requires minimal technical skill, the potential impact on business operations and data integrity necessitates prompt remediation. Security teams should also conduct comprehensive vulnerability assessments to identify all systems utilizing the affected technology and implement proper access controls to minimize the attack surface. The CVSS vector specifically indicates that if data processing occurs without network-based data reception, the vulnerability's severity may be reduced, but organizations should still implement comprehensive security measures to protect against potential exploitation pathways.
