CVE-2019-2457 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-2019-2457 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 technology stack. The flaw represents a significant security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, making it particularly concerning for organizations that deploy this technology in production environments.
The technical nature of this vulnerability stems from inadequate input validation within the Outside In Technology processing pipeline. When network data is passed directly to the Outside In Technology code, the system fails to properly validate or sanitize incoming payloads, creating opportunities for malicious actors to craft specially crafted requests that can trigger unintended behavior within the processing engine. This weakness manifests as a partial denial of service condition, where the vulnerability allows attackers to disrupt the availability of the affected system without necessarily gaining full system compromise or data access privileges. The vulnerability's classification under CWE-20 indicates a fundamental flaw in input validation that directly contributes to the availability impact.
From an operational perspective, this vulnerability presents a substantial risk to organizations utilizing Oracle Fusion Middleware solutions, particularly those that process external document uploads or handle network-based content processing. The CVSS 3.0 score of 5.3 reflects the moderate severity of the availability impact, with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L indicating that network-based attacks require low complexity and no authentication, while the scope remains unchanged and no confidentiality or integrity impacts are observed. The partial denial of service condition can significantly disrupt business operations, especially in environments where document processing capabilities are critical to daily operations, potentially affecting workflow automation, document management systems, and content processing applications that rely on this technology stack.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates to bring their Outside In Technology installations to supported versions that address this vulnerability. Network segmentation and access controls should be strengthened to limit exposure of systems running this technology to untrusted networks. Additionally, implementing monitoring and logging of HTTP traffic to and from affected systems can help detect potential exploitation attempts. The mitigation strategy should align with ATT&CK framework's T1190 (Exploit Public-Facing Application) and T1499 (Endpoint Denial of Service) techniques, emphasizing the need for proactive network defense measures. Organizations should also consider implementing application firewalls and input validation controls at network boundaries to prevent malformed requests from reaching the vulnerable processing engines, as this vulnerability specifically targets the data processing pipeline rather than authentication or authorization mechanisms.
