CVE-2019-2463 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 update, insert or delete access to some 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 6.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

The vulnerability identified as CVE-2019-2463 affects Oracle Outside In Technology, a critical component within Oracle Fusion Middleware that serves as a suite of software development kits enabling applications to process various document formats. This vulnerability specifically resides within the Outside In Filters subcomponent and impacts versions 8.5.3 and 8.5.4 of the Oracle Fusion Middleware suite. The flaw represents a significant security weakness that can be exploited by unauthenticated attackers without requiring any prior access credentials or privileges, making it particularly dangerous in networked environments where the technology is deployed.
The technical nature of this vulnerability stems from insufficient input validation within the Outside In Technology processing mechanisms, which allows maliciously crafted HTTP requests to be processed without proper sanitization. This weakness creates pathways for attackers to manipulate the underlying data processing capabilities of the technology stack. The vulnerability's classification as easily exploitable indicates that the attack surface is relatively broad and that successful exploitation can lead to unauthorized data modification operations including update, insert, and delete actions against data accessible through the affected Oracle Outside In Technology components. Additionally, attackers can potentially cause partial denial of service conditions that disrupt normal operational functionality of the affected systems.
The operational impact of CVE-2019-2463 extends beyond simple data integrity concerns to encompass availability risks that can compromise system reliability and business continuity. Organizations utilizing Oracle Fusion Middleware with the affected Outside In Technology versions face potential unauthorized access to sensitive data processing capabilities, which could result in data corruption or manipulation. The CVSS score of 6.5 reflects the moderate to high severity of this vulnerability, with integrity and availability impacts being the primary concerns. This vulnerability is particularly dangerous because it can be exploited remotely over HTTP networks without requiring authentication, making it accessible to any attacker with network connectivity to the affected systems.
From a cybersecurity perspective, this vulnerability aligns with CWE-20 (Improper Input Validation) and represents a classic example of how insufficient data sanitization can create attack vectors in software development kits. The ATT&CK framework would categorize this vulnerability under T1190 (Exploit Public-Facing Application) and potentially T1499 (Endpoint Denial of Service) given the partial denial of service capability. Organizations should implement immediate mitigations including applying Oracle's security patches, implementing network segmentation to limit access to affected systems, and monitoring for suspicious HTTP traffic patterns that may indicate exploitation attempts. The vulnerability's impact assessment should consider the specific implementation of Outside In Technology within each organization's software stack, as the CVSS vector assumes direct network data processing but real-world scenarios may vary based on how the technology is integrated into existing applications and systems.
