CVE-2019-2465 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. 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 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

The vulnerability identified as CVE-2019-2465 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 and manipulate various file formats. This specific flaw exists within the Outside In Filters subcomponent and affects Oracle Fusion Middleware versions 8.5.3 and 8.5.4, representing a significant security weakness that could be exploited by malicious actors without requiring authentication credentials. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based HTTP access to compromise the affected system, making it particularly dangerous in environments where network exposure is common.
The technical nature of this vulnerability stems from insufficient input validation within the Outside In Technology processing pipeline, which allows attackers to craft malicious requests that can trigger unauthorized data access patterns. The flaw specifically impacts the confidentiality aspects of the system by enabling unauthorized read access to a subset of data that would normally be protected within the Outside In Technology environment. This represents a CWE-20 vulnerability category related to improper input validation, where the system fails to properly sanitize or validate input data before processing. The attack vector is classified as network-based with low access complexity, meaning that an attacker positioned on the same network segment or able to reach the target system through HTTP protocols can exploit this weakness without requiring any privileged credentials or additional authentication mechanisms.
The operational impact of CVE-2019-2465 extends beyond simple data theft, as it represents a potential gateway for more sophisticated attacks within Oracle Fusion Middleware environments. When data is processed through Outside In Technology components, attackers can potentially extract sensitive information that may include proprietary documents, configuration details, or other confidential data that applications depend upon for proper operation. The CVSS score of 5.3 reflects the moderate severity of this vulnerability, though it should be noted that the actual risk assessment may vary depending on how the underlying software integrates with the Outside In Technology code. If applications properly validate and sanitize network data before passing it to Outside In Technology components, the effective CVSS score could be significantly reduced, but this protective measure is not guaranteed to be implemented consistently across all deployments.
Organizations affected by this vulnerability should implement immediate mitigations including applying Oracle's official security patches and updates, which would address the root cause of the input validation weakness. Network segmentation and access controls should be strengthened to limit exposure of affected systems to untrusted networks, while monitoring should be enhanced to detect potential exploitation attempts. The ATT&CK framework would classify this vulnerability under the T1071.004 technique for application layer protocol usage, specifically HTTP communications, and potentially T1566 for initial access through network-based exploitation. Additionally, organizations should conduct thorough vulnerability assessments to identify all instances of affected Oracle Fusion Middleware installations and ensure that proper data validation mechanisms are implemented within applications that utilize Outside In Technology components to prevent similar vulnerabilities from being exploited in the future.
