CVE-2019-2462 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. While the vulnerability is in Oracle Outside In Technology, attacks may significantly impact additional products. 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 7.2 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L).

The vulnerability identified as CVE-2019-2462 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 document formats. This specific weakness affects versions 8.5.3 and 8.5.4 of the Outside In Filters subcomponent, which serves as the primary interface for handling document parsing and conversion operations. The flaw represents a significant security concern as it operates within the core processing infrastructure that numerous enterprise applications depend upon for document handling capabilities.
The technical implementation of this vulnerability stems from insufficient input validation within the Outside In Technology processing pipeline, creating a pathway for malicious actors to manipulate the data flow through HTTP protocols. This allows an unauthenticated attacker positioned on the network to exploit the weakness without requiring prior authorization or credentials, making the attack surface particularly broad. The vulnerability manifests when the system processes documents that contain crafted malicious content, which then triggers unexpected behavior within the processing engine. This flaw falls under the CWE-20 category of "Improper Input Validation" and specifically aligns with the ATT&CK technique T1059.007 for "Command and Scripting Interpreter: Python" and T1190 for "Exploit Public-Facing Application" within the enterprise attack framework.
The operational impact of CVE-2019-2462 extends beyond the immediate Outside In Technology components to potentially compromise multiple downstream applications that utilize this technology for document processing. Successful exploitation enables attackers to achieve unauthorized read access to sensitive data within the affected system's scope, while simultaneously providing the capability to execute partial denial of service attacks that can disrupt document processing operations. The CVSS 3.0 base score of 7.2 reflects the moderate to high severity of this vulnerability, with confidentiality and availability impacts rated as medium and low respectively. The assessment assumes that data flows directly from network sources to the Outside In Technology code, though the actual risk may be reduced if applications implement proper data sanitization measures before passing information to the vulnerable components.
Organizations should implement immediate mitigations including network segmentation to limit access to affected systems, deployment of web application firewalls to filter malicious HTTP requests, and application-level input validation to prevent malformed data from reaching the vulnerable processing engines. The recommended remediation strategy involves upgrading to patched versions of Oracle Fusion Middleware, specifically targeting the affected Outside In Technology versions, while also implementing monitoring procedures to detect anomalous document processing patterns that may indicate exploitation attempts. Security teams should also consider the broader implications of this vulnerability across their enterprise environment, as the Outside In Technology SDKs are integrated into numerous applications and services that may be indirectly impacted by compromised processing capabilities.
