CVE-2019-2612 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-2019-2612 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 and manipulate 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 concern as it operates within the core document processing functionality that many enterprise applications depend upon for handling file operations and data manipulation tasks.
The technical nature of this vulnerability stems from insufficient input validation within the Outside In Technology processing pipeline. An attacker can exploit this weakness through unauthenticated network access via HTTP protocols to manipulate the processing of files or data streams that pass through the affected component. This vulnerability manifests as a partial denial of service condition where the attacker can cause disruptions to the normal operation of the technology while simultaneously gaining unauthorized read access to certain data within the affected system. The vulnerability's exploitability is classified as easily accessible due to the lack of authentication requirements and the network-based attack vector.
From an operational impact perspective, this vulnerability creates a dual threat to system security and availability. The unauthorized read access capability allows attackers to potentially extract sensitive data that might be processed through the Outside In Technology components, while the partial denial of service component can disrupt normal business operations by affecting document processing capabilities. The CVSS 3.0 base score of 6.5 reflects the balance between confidentiality and availability impacts, with the assessment assuming that network-received data is directly passed to the vulnerable code without intermediate sanitization. However, if data processing occurs in environments where network data is not directly passed to the vulnerable code, the actual risk assessment may be reduced.
Organizations utilizing affected versions of Oracle Fusion Middleware should prioritize immediate remediation through official Oracle patches and updates to address this vulnerability. The security community recognizes this issue as aligning with CWE-20, which covers "Improper Input Validation," and the attack patterns associated with it align with MITRE ATT&CK techniques for credential access and denial of service operations. The vulnerability's classification as a network-based attack with no authentication requirements makes it particularly dangerous in environments where the affected components are exposed to untrusted networks or internet-facing services. Organizations should also consider implementing network segmentation and access controls to limit exposure while permanent patches are deployed.
