CVE-2019-2610 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 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 6.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L).

The vulnerability identified as CVE-2019-2610 resides within Oracle Outside In Technology, a critical component of Oracle Fusion Middleware that functions as a suite of software development kits designed to handle document processing and conversion tasks. This particular flaw affects versions 8.5.3 and 8.5.4 of the Outside In Filters subcomponent, which serves as a foundational element for processing various document formats within Oracle's middleware ecosystem. The vulnerability presents a significant security risk as it operates within the core processing infrastructure that handles document data traversal and manipulation, making it a prime target for malicious actors seeking to exploit weaknesses in document handling systems.
The technical flaw manifests as an insufficient input validation issue that allows attackers to manipulate the processing pipeline through specially crafted HTTP requests. This vulnerability operates at the protocol level where network data is passed directly to the Outside In Technology code, creating a direct attack surface that bypasses normal authentication mechanisms. The flaw specifically affects how the system processes incoming data streams, particularly when these streams contain malformed or specially constructed payloads that can trigger unexpected behavior within the document processing engine. This vulnerability aligns with CWE-20, which describes improper input validation, and represents a classic example of how inadequate sanitization of network inputs can lead to unauthorized access and system compromise.
The operational impact of this vulnerability extends beyond simple data exposure, creating a multi-faceted threat landscape that affects both confidentiality and availability aspects of the targeted systems. Successful exploitation enables unauthenticated attackers to gain unauthorized read access to sensitive data that would normally be restricted within the Outside In Technology environment, potentially exposing proprietary documents, confidential information, or system metadata. Additionally, the vulnerability can be leveraged to execute partial denial of service attacks, where the targeted system experiences degraded performance or temporary unavailability due to resource exhaustion or processing errors. The CVSS score of 6.5 reflects the balance between the ease of exploitation and the potential damage, with the low attack complexity and lack of required privileges making this vulnerability particularly dangerous in real-world scenarios.
Organizations utilizing affected versions of Oracle Fusion Middleware must implement immediate mitigation strategies to protect their systems from exploitation attempts. The primary recommendation involves applying Oracle's security patches and updates as soon as they become available, which typically address the input validation gaps that enable this vulnerability. Network segmentation and access controls should be strengthened to limit exposure of the vulnerable components to untrusted networks, while implementing proper monitoring and logging mechanisms to detect potential exploitation attempts. The vulnerability's classification under the ATT&CK framework would place it within the reconnaissance and initial access phases, specifically targeting the 'T1059 Command and Scripting Interpreter' and 'T1190 Exploit Public-Facing Application' techniques. Organizations should also consider implementing network-based intrusion detection systems that can identify malicious traffic patterns associated with this specific vulnerability, as the attack vectors typically involve HTTP-based requests that follow predictable patterns of exploitation.
