CVE-2019-2903 in Outside In Technology
Summary
by MITRE
Vulnerability in the Oracle Outside In Technology product of Oracle Fusion Middleware (component: 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-2019-2903 resides within Oracle Outside In Technology, a comprehensive suite of software development kits that provides document processing capabilities within Oracle Fusion Middleware environments. This specific flaw affects version 8.5.4 of the Outside In Filters component, which serves as a critical processing layer for various document formats and data types. The vulnerability manifests as a security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, representing a significant risk to organizations utilizing Oracle Fusion Middleware solutions.
The technical exploitation of this vulnerability occurs through the processing of network-received data by the Outside In Technology code, which lacks proper input validation mechanisms. This weakness enables attackers to manipulate the system's behavior through crafted HTTP requests that are passed directly to the vulnerable components. The vulnerability's classification as easily exploitable indicates that minimal technical expertise or resources are required to successfully compromise the affected system, making it particularly dangerous in production environments where such systems may be exposed to untrusted networks.
The operational impact of this vulnerability encompasses multiple security dimensions that collectively undermine the integrity and availability of affected systems. Attackers can achieve unauthorized read access to sensitive data subsets, potentially exposing confidential information processed through the Outside In Technology components. Additionally, the vulnerability enables unauthorized modification capabilities allowing attackers to update, insert, or delete data within the accessible system resources. The partial denial of service component of this vulnerability can disrupt normal operations by affecting availability of critical document processing services, potentially impacting business continuity and operational efficiency.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-20 (Improper Input Validation) and represents a classic example of insufficient validation of input data. The attack surface is particularly concerning when considering the widespread use of Oracle Fusion Middleware solutions across enterprise environments, where the Outside In Technology components are often integrated into critical business applications. The CVSS 3.0 scoring of 7.3 reflects the moderate to high severity of impact, with equal weighting across confidentiality, integrity, and availability metrics, indicating that the vulnerability affects core security tenets of the system.
Organizations should implement immediate mitigations including network segmentation to limit direct access to affected systems, deployment of web application firewalls to filter malicious HTTP requests, and application of Oracle's security patches as soon as they become available. The vulnerability's assessment as potentially lower severity when data is not received over network protocols suggests that organizations should evaluate their specific deployment configurations and implement defense-in-depth strategies. Regular security assessments should be conducted to identify other potential attack vectors that might leverage similar weaknesses in the broader Oracle Fusion Middleware ecosystem, ensuring comprehensive protection against evolving threat landscapes.
