CVE-2019-2464 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. 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 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

The vulnerability identified as CVE-2019-2464 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 vulnerability specifically affects versions 8.5.3 and 8.5.4 of the Outside In Filters subcomponent, which serves as the core processing engine for document conversion and manipulation tasks. The flaw represents a significant security weakness that could be exploited by unauthenticated attackers without requiring any special privileges or authentication credentials, making it particularly dangerous in environments where network exposure is common.
The technical nature of this vulnerability stems from insufficient input validation within the Outside In Technology processing pipeline, allowing maliciously crafted HTTP requests to trigger unauthorized data access patterns. This weakness operates at the application layer and leverages the network-based attack vector described in the CVSS scoring, where attackers can exploit the vulnerability remotely without needing physical access or prior authentication. The vulnerability's classification as easily exploitable indicates that the attack surface is broad and the implementation requires minimal technical expertise to successfully compromise the affected systems. This aligns with CWE-20, which identifies improper input validation as a fundamental weakness that can lead to various security issues including information disclosure.
The operational impact of this vulnerability extends beyond simple data theft, as it specifically targets the confidentiality aspect of the information security triad. Successful exploitation enables unauthorized read access to a subset of data that is accessible through the Outside In Technology component, potentially exposing sensitive documents, metadata, or system information that applications relying on this technology might be processing. The vulnerability's CVSS base score of 5.3 reflects the moderate severity level, though this assessment assumes that the software directly passes network-received data to the vulnerable Outside In Technology code without additional processing or sanitization. When data processing occurs through other channels or when additional security controls are in place, the effective risk may be reduced but the fundamental vulnerability remains present.
Organizations utilizing affected versions of Oracle Fusion Middleware should prioritize immediate remediation through official Oracle patches and updates, as the vulnerability exists in widely deployed enterprise software components. The attack surface is particularly concerning given that Outside In Technology is commonly integrated into business applications that handle sensitive corporate data, making this vulnerability a potential gateway for data exfiltration or further exploitation. Security teams should also implement network segmentation controls and monitoring of HTTP traffic to detect potential exploitation attempts, while considering the broader context of the ATT&CK framework where such vulnerabilities might be leveraged for initial access or lateral movement within compromised networks. Additional mitigations include disabling unnecessary HTTP interfaces, implementing web application firewalls, and conducting thorough vulnerability assessments of all applications that utilize the affected technology to ensure complete protection against this and similar threats.
