CVE-2019-2467 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 ability to cause a hang or frequently repeatable crash (complete 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 7.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

The vulnerability identified as CVE-2019-2467 resides within Oracle Outside In Technology, a critical component of Oracle Fusion Middleware that functions as a comprehensive suite of software development kits designed to handle document processing and conversion tasks. 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 handling various document formats within Oracle Fusion Middleware environments. The flaw manifests as a denial of service condition that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, representing a significant security weakness in enterprise document processing infrastructure.
The technical nature of this vulnerability stems from inadequate input validation within the Outside In Technology processing pipeline, creating a condition where malformed or specially crafted data can trigger system instability. This flaw operates at the protocol level where network-received data is directly passed to the Outside In Technology code without sufficient sanitization or boundary checking. The vulnerability's classification as easily exploitable indicates that minimal technical expertise is required to craft successful attack payloads, making it particularly dangerous in production environments where such systems are exposed to untrusted network traffic. The complete denial of service impact means that successful exploitation can cause the affected system to hang or repeatedly crash, effectively rendering the document processing capabilities unavailable to legitimate users.
From an operational perspective, this vulnerability poses substantial risk to organizations relying on Oracle Fusion Middleware for document management, content processing, and enterprise application integration. The availability impact score of 7.5 indicates that the vulnerability can severely disrupt business operations by causing complete system unavailability, potentially affecting critical processes such as document conversion, content indexing, and automated workflow execution. The CVSS vector analysis reveals that the attack requires no authentication, low complexity, and leverages network access, making it particularly attractive to malicious actors seeking to disrupt services. The vulnerability's impact extends beyond simple system crashes, as it can potentially affect the entire middleware infrastructure that depends on Outside In Technology for document handling capabilities.
Organizations should implement immediate mitigations including network segmentation to limit access to affected systems, deploying firewall rules to restrict HTTP access to necessary administrative interfaces, and applying Oracle's security patches as soon as they become available. The vulnerability's classification under CWE-129 (Improper Validation of Input) and potential mapping to ATT&CK technique T1499.004 (Endpoint Denial of Service) emphasizes the need for comprehensive network monitoring and intrusion detection system configuration. Additionally, organizations should consider implementing input validation controls at application level to prevent malformed data from reaching the Outside In Technology components, and establish robust incident response procedures for handling potential denial of service events. The CVSS score assumption about network-based data handling highlights the importance of understanding how data flows through the system architecture to properly assess risk and implement appropriate controls.
