CVE-2017-3230 in Fusion Middleware MapViewer
Summary
by MITRE
Vulnerability in the Oracle Fusion Middleware MapViewer component of Oracle Fusion Middleware (subcomponent: Map Builder). Supported versions that are affected are 11.1.1.9, 12.2.1.1 and 12.2.1.2. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Fusion Middleware MapViewer. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Fusion Middleware MapViewer accessible data as well as unauthorized read access to a subset of Oracle Fusion Middleware MapViewer accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Fusion Middleware MapViewer. CVSS 3.0 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L).

The vulnerability identified as CVE-2017-3230 resides within the Oracle Fusion Middleware MapViewer component, specifically within the Map Builder subcomponent. This critical security flaw affects multiple versions including 11.1.1.9, 12.2.1.1, and 12.2.1.2, representing a significant risk to organizations utilizing Oracle Fusion Middleware solutions. The vulnerability operates at the application layer and manifests through the MapViewer's HTTP interface, making it accessible to remote attackers without requiring any authentication credentials. The CVSS base score of 8.6 reflects the severity of this flaw, with impacts spanning confidentiality, integrity, and availability. This vulnerability falls under the CWE category of 264, which encompasses permissions, privileges, and access control issues, specifically manifesting as insufficient access control mechanisms within the web application layer.
The technical exploitation of this vulnerability enables attackers to perform unauthorized operations against the MapViewer component through unauthenticated HTTP requests. Attackers can leverage this flaw to create, delete, or modify critical data within the MapViewer environment, potentially compromising the integrity of mapping applications and associated datasets. Additionally, the vulnerability permits unauthorized read access to sensitive data subsets, exposing confidential mapping information and potentially revealing organizational infrastructure details. The partial denial of service aspect means that attackers can disrupt service availability to some degree, affecting legitimate users' ability to access mapping functionalities. The low attack complexity and lack of required privileges make this vulnerability particularly dangerous as it can be exploited by anyone with network access to the affected system. This aligns with ATT&CK technique T1213.002 for data from information repositories, where adversaries gain unauthorized access to data through application-level vulnerabilities.
Organizations deploying affected Oracle Fusion Middleware versions face substantial operational risks from this vulnerability, as it can lead to data compromise, service disruption, and potential regulatory violations. The vulnerability's impact extends beyond immediate data exposure to encompass potential business continuity issues, as partial denial of service can affect mapping services critical to operations. Security teams must prioritize patch management for this vulnerability, as Oracle has released patches addressing the access control weakness in subsequent updates. The vulnerability demonstrates the importance of securing web application interfaces and implementing proper authentication mechanisms even for components that may appear to be internal or trusted. Organizations should also consider implementing network segmentation to limit exposure of vulnerable systems and deploy web application firewalls to detect and prevent exploitation attempts. The CVSS vector indicates that the vulnerability requires no user interaction and can be exploited remotely, making it particularly attractive to automated attack tools and increasing the potential attack surface for organizations using affected versions.
