CVE-2018-2834 in Data Visualization Desktop
Summary
by MITRE
Vulnerability in the Oracle Data Visualization Desktop component of Oracle Fusion Middleware (subcomponent: Security). The supported version that is affected is 12.2.4.1.1. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Data Visualization Desktop executes to compromise Oracle Data Visualization Desktop. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Data Visualization Desktop, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Data Visualization Desktop accessible data as well as unauthorized read access to a subset of Oracle Data Visualization Desktop accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Data Visualization Desktop. Note: Please refer to Doc ID My Oracle Support Note 2384640.1 for instructions on how to address this issue. CVSS 3.0 Base Score 8.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:H).

The vulnerability identified as CVE-2018-2834 resides within Oracle Data Visualization Desktop, a component of Oracle Fusion Middleware that falls under the Security subcomponent category. This vulnerability affects version 12.2.4.1.1 of the software and represents a critical security flaw that can be exploited by attackers with access to the underlying infrastructure where the application executes. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring extensive technical expertise or privileged access to the system. The CVSS 3.0 base score of 8.5 reflects the severity of impact across confidentiality, integrity, and availability dimensions, demonstrating that this vulnerability can cause substantial damage to the target environment.
The technical nature of this vulnerability stems from insufficient security controls within Oracle Data Visualization Desktop that allow an unauthenticated attacker with infrastructure access to compromise the application's integrity and availability. The flaw requires human interaction from individuals other than the attacker, suggesting that social engineering or physical access scenarios may be necessary for exploitation to occur. However, once the initial access point is established, the vulnerability can be leveraged to execute unauthorized operations against the application's data and functionality. The attack vector analysis shows AV:L (Adjacent Network) with low attack complexity and no privilege requirements, making it particularly dangerous as it can be exploited from the local network or through physical access to the system.
The operational impact of this vulnerability extends beyond the immediate compromise of Oracle Data Visualization Desktop itself, as successful attacks can significantly affect additional products within the Oracle Fusion Middleware ecosystem. Attackers can potentially create, delete, or modify critical data within the application's accessible data stores, while also gaining unauthorized read access to sensitive information. The vulnerability's potential to cause complete denial of service through hangs or frequently repeatable crashes represents a particularly severe threat to business continuity and operational availability. This type of vulnerability aligns with CWE-284 (Improper Access Control) and CWE-310 (Cryptographic Issues) categories, indicating weak access control mechanisms and potential cryptographic weaknesses in the authentication process. The attack surface is further expanded by the fact that the vulnerability exists within a desktop application that may be installed on various system configurations, potentially affecting multiple environments.
Organizations should implement immediate mitigations to address this vulnerability by following the guidance provided in Oracle Support Document ID 2384640.1, which outlines specific procedures for patching and configuration adjustments. The recommended approach includes applying the appropriate Oracle security patches and implementing network segmentation to limit access to systems running Oracle Data Visualization Desktop. Additionally, organizations should review their access control policies and ensure that only authorized personnel have access to infrastructure where the application executes. The vulnerability's characteristics suggest that standard network monitoring and intrusion detection systems should be configured to detect unusual access patterns or unauthorized modifications to data visualization resources. Implementing principle of least privilege access controls and regularly auditing system access logs can help identify potential exploitation attempts. Security teams should also consider the potential for lateral movement through the compromised system and implement appropriate network access controls to prevent attackers from using the vulnerability as a foothold to access other systems within the enterprise environment.
