CVE-2019-2902 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-2019-2902 resides within Oracle Outside In Technology, a comprehensive suite of software development kits that enable applications to process and manipulate various document formats and file types. This particular flaw exists within the Outside In Filters component of Oracle Fusion Middleware, specifically affecting version 8.5.4 which represents a supported release. The vulnerability manifests as a critical security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, making it particularly dangerous in environments where such services are exposed to external networks.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Outside In Technology framework. Attackers can leverage this weakness to perform unauthorized operations against the affected system, including modifying, inserting, or deleting data within the accessible database components. Additionally, the flaw enables unauthorized read access to sensitive data subsets, while simultaneously providing the capability to execute partial denial of service attacks that can disrupt normal operational functionality. The vulnerability's exploitability is classified as easily accessible, meaning that attackers require minimal technical expertise or resources to successfully compromise the system, which significantly increases the potential impact.
From an operational perspective, the implications of this vulnerability extend beyond simple data compromise to encompass complete system integrity and availability concerns. The CVSS 3.0 scoring system assigns a base score of 7.3, reflecting the severity of the impact across confidentiality, integrity, and availability domains. The attack vector is classified as network-based (AV:N) with low complexity requirements (AC:L) and no privileged access requirements (PR:N), making it particularly attractive to threat actors seeking automated exploitation. The vulnerability's potential for causing partial denial of service means that organizations could experience disrupted operations, while the data access capabilities could lead to information disclosure and unauthorized modifications that may go undetected for extended periods.
Organizations utilizing Oracle Outside In Technology should implement immediate mitigation strategies including network segmentation to restrict access to affected systems, deployment of web application firewalls to monitor and filter malicious traffic, and implementation of strict access controls for HTTP endpoints. The CVSS scoring indicates that the severity is highly dependent on how the technology is integrated within the broader software architecture, suggesting that organizations should conduct thorough assessments of their data processing pipelines to determine if network-based data handling creates additional exposure. Security teams should also consider implementing monitoring solutions specifically designed to detect anomalous access patterns that could indicate exploitation attempts, as the vulnerability's characteristics align with common attack patterns documented in the attack tactics and techniques framework. This vulnerability exemplifies the importance of maintaining current security patches and implementing defense-in-depth strategies that protect against both known and emerging threats within complex middleware environments.
