CVE-2019-2475 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-2019-2475 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 specific flaw manifests in the Outside In Filters subcomponent and affects versions 8.5.3 and 8.5.4 of the technology stack. The vulnerability represents a significant security concern as it operates as an easily exploitable weakness that permits unauthenticated attackers to compromise the system through network-based HTTP access. The technical nature of this vulnerability falls under CWE-119, which encompasses memory access violations and buffer overflows that can lead to denial of service conditions. The attack vector specifically leverages HTTP protocols to deliver malicious payloads directly to the vulnerable Outside In Technology code, making it particularly dangerous for systems that process external document data.
The operational impact of this vulnerability extends beyond simple service disruption, as successful exploitation can result in complete denial of service conditions where the Oracle Outside In Technology experiences hangs or frequently repeatable crashes. This type of vulnerability directly maps to the ATT&CK technique T1499.004, which involves network disruption through resource exhaustion and system instability. The CVSS score of 7.5 reflects the high availability impact and the ease with which an attacker can exploit this weakness without requiring authentication or specialized user interaction. The vulnerability's design flaw allows for network-based data processing that passes directly to the vulnerable code, creating a pathway for attackers to destabilize systems that rely on Outside In Technology for document handling capabilities. Organizations utilizing this technology for processing documents from external sources face the highest risk, as the attack can be executed without any prior authentication or privileged access.
Mitigation strategies for CVE-2019-2475 should prioritize immediate patch management and system hardening measures to prevent exploitation. Organizations must implement network segmentation to restrict access to systems running Outside In Technology, particularly those that process external document data. The recommended approach includes deploying firewalls and access controls to limit HTTP traffic to only trusted sources and implementing network monitoring to detect anomalous patterns associated with exploitation attempts. Security teams should also consider disabling unnecessary HTTP endpoints that interface with Outside In Technology components and regularly audit system configurations to ensure proper access controls are in place. Additionally, implementing intrusion detection systems that can identify potential exploitation attempts through signature-based detection methods provides an additional layer of protection. Organizations should also conduct regular vulnerability assessments to identify other potential weaknesses in their document processing pipelines and maintain updated incident response procedures specifically tailored to address denial of service attacks targeting middleware components. The vulnerability's classification under CVSS 3.0 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H demonstrates the critical nature of this weakness and the importance of immediate remediation efforts to prevent potential system compromise and service disruption.
