CVE-2018-3095 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-2018-3095 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 various document formats. This specific flaw manifests in the Outside In Filters subcomponent version 8.5.3, representing a significant security weakness that could potentially expose organizations to unauthorized data access and service disruption. The vulnerability operates at the protocol level where network-based attacks can be executed through HTTP connections, making it particularly dangerous in environments where external network access is permitted.
This vulnerability represents a sophisticated security flaw classified as a buffer overflow or memory corruption issue within the document processing functionality of Outside In Technology. The technical implementation appears to lack proper input validation mechanisms when processing specially crafted documents or data streams passed through HTTP protocols. The vulnerability requires an attacker to have network access and successfully deliver malicious content to a target system, though the attack vector becomes more severe when considering that the exploit can be executed without authentication credentials. The CVSS score of 7.1 reflects the high potential impact on confidentiality and availability, with the base score indicating a medium severity attack complexity requirement.
The operational impact of this vulnerability extends beyond simple data compromise, as it can lead to complete access to all data accessible through the affected Outside In Technology components. Attackers who successfully exploit this vulnerability can potentially access critical corporate data, intellectual property, or sensitive business information that relies on the document processing capabilities of Oracle Fusion Middleware. The partial denial of service component of this vulnerability means that even if attackers cannot fully compromise the system, they can still disrupt normal operations and potentially cause service interruptions that impact business continuity. The requirement for human interaction suggests that social engineering or targeted delivery methods may be necessary to successfully execute attacks, though this does not diminish the overall risk profile.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates, implementing network segmentation to limit access to affected systems, and deploying network monitoring solutions to detect anomalous HTTP traffic patterns. The vulnerability's classification under CWE categories related to improper input validation and memory safety issues indicates that defensive measures should focus on validating all inputs before processing and implementing robust error handling mechanisms. From an ATT&CK framework perspective, this vulnerability aligns with techniques involving exploitation of remote services and credential dumping, potentially enabling lateral movement within affected networks. System administrators should also consider disabling unnecessary HTTP services and implementing strict access controls to minimize the attack surface while maintaining operational functionality of legitimate business processes relying on the Outside In Technology components.
