CVE-2019-2472 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 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

The vulnerability identified as CVE-2019-2472 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 file formats. This specific flaw manifests in the Outside In Filters subcomponent, which handles file format processing and conversion operations. The vulnerability affects Oracle Fusion Middleware versions 8.5.3 and 8.5.4, making these particular releases susceptible to exploitation by malicious actors. The security implications are significant as Outside In Technology serves as a foundational element for numerous enterprise applications that rely on file processing capabilities, creating a potential attack surface that extends far beyond the immediate component.
This vulnerability represents a classic denial of service scenario where an unauthenticated attacker can exploit a network-based HTTP interface to compromise the target system. The technical flaw stems from insufficient input validation within the file processing pipeline, allowing maliciously crafted data to trigger abnormal behavior in the Outside In Filters functionality. The vulnerability's exploitability is rated as easily exploitable due to the lack of authentication requirements and the accessible HTTP network interface. When exploited, the vulnerability enables attackers to perform partial denial of service operations against the Oracle Outside In Technology, disrupting legitimate file processing operations while maintaining system availability for other functions. The underlying mechanism involves the processing of malformed input data that causes the filters to enter an unstable state, potentially leading to resource exhaustion or application crashes.
The operational impact of CVE-2019-2472 extends beyond simple service disruption, as it affects the core file processing capabilities that many enterprise applications depend upon. Organizations utilizing Oracle Fusion Middleware with affected versions may experience partial system unavailability when processing certain file formats, particularly those handled by the vulnerable Outside In Filters. The CVSS 3.0 scoring of 5.3 reflects the availability impact, with the base score indicating a moderate severity threat that can significantly affect business operations. The vulnerability's network accessibility means that attackers can potentially exploit it from remote locations without requiring prior authentication credentials. The actual CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) confirms the low attack complexity and lack of user interaction requirements, while the unspecified software dependencies mean that the true impact varies based on how the Outside In Technology code is integrated into specific applications. This vulnerability aligns with CWE-121, which describes buffer overflow conditions, and relates to ATT&CK technique T1499.004 for network denial of service attacks.
Organizations should implement immediate mitigations including patching affected Oracle Fusion Middleware installations to versions that contain the necessary security fixes for CVE-2019-2472. Network segmentation and firewall rules should be configured to limit access to the vulnerable HTTP interfaces, particularly when the Outside In Technology components are not directly exposed to untrusted networks. Monitoring should be enhanced to detect unusual patterns in file processing requests that might indicate exploitation attempts. The vulnerability demonstrates the importance of maintaining current security patches for middleware components, as these often serve as critical infrastructure elements that support multiple applications and business processes. Organizations should also conduct thorough assessments of their file processing workflows to understand the potential impact and implement additional defensive measures such as input sanitization and rate limiting to reduce the attack surface and prevent successful exploitation attempts.
