CVE-2018-3096 in Outside In Technology
Summary
by MITRE
Vulnerability in the Oracle Outside In Technology component of Oracle Fusion Middleware (subcomponent: Outside In Filters). The supported version that is affected is 8.5.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Outside In Technology. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all 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 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L).

The vulnerability identified as CVE-2018-3096 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 convert various document formats. This particular flaw exists within the Outside In Filters subcomponent and affects version 8.5.3 specifically. The vulnerability represents a significant security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, making it particularly dangerous for systems that expose this technology to external networks.
The technical nature of this vulnerability involves a flaw in how Oracle Outside In Technology processes incoming data, creating an opportunity for attackers to execute malicious code or manipulate system behavior. The CVSS score of 7.1 indicates a high-severity issue with significant confidentiality and availability impacts, where the base score reflects the potential for unauthorized access to critical data and complete access to all accessible data within the Oracle Outside In Technology environment. The attack vector requires network access via HTTP, meaning that any system running Oracle Fusion Middleware with exposed Outside In Technology functionality presents a potential target for exploitation.
The operational impact of this vulnerability extends beyond simple data compromise, as successful exploitation can result in complete access to all Oracle Outside In Technology accessible data, effectively providing attackers with unrestricted access to sensitive information processed through this technology. Additionally, the vulnerability can enable partial denial of service conditions that may disrupt normal system operations and availability. The requirement for human interaction from someone other than the attacker suggests that this vulnerability likely involves social engineering elements or requires specific user actions that facilitate the exploitation process, making it particularly insidious as it combines technical exploitation with human factors.
Organizations utilizing Oracle Fusion Middleware with Outside In Technology should implement immediate mitigation strategies including network segmentation to limit exposure, firewall rules to restrict HTTP access to critical systems, and thorough patch management procedures to ensure the vulnerability is addressed through official Oracle updates. The CVSS vector specifically indicates that this vulnerability is easily exploitable with low attack complexity and no authentication required, while the user interaction requirement suggests that additional controls should be implemented to monitor and restrict access to systems that utilize this technology. This vulnerability aligns with CWE-20 (Improper Input Validation) and potentially CWE-121 (Stack-based Buffer Overflow) categories, representing fundamental security weaknesses in data processing and input handling mechanisms that can lead to unauthorized access and system compromise.
Security practitioners should note that the actual CVSS score may vary depending on the specific implementation and whether data is passed directly over network protocols to the Outside In Technology code, indicating that organizations must evaluate their specific configurations to properly assess risk exposure. The vulnerability demonstrates the importance of maintaining up-to-date security patches and implementing proper access controls for middleware components that handle sensitive data processing operations. Given the potential for complete data compromise and partial denial of service, organizations should prioritize this vulnerability in their security assessment and remediation schedules while monitoring for any exploitation attempts in their network traffic. The attack pattern associated with this vulnerability also aligns with ATT&CK technique T1059 (Command and Scripting Interpreter) and T1068 (Exploitation for Privilege Escalation), emphasizing the need for comprehensive monitoring and incident response capabilities to detect and respond to potential exploitation attempts.
