CVE-2017-3507 in Service Bus
Summary
by MITRE
Vulnerability in the Oracle Service Bus component of Oracle Fusion Middleware (subcomponent: Web Console Design). Supported versions that are affected are 12.1.3.0.0, 12.2.1.0.0, 12.2.1.1.0 and 12.2.1.2.0. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Service Bus. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Service Bus accessible data as well as unauthorized read access to a subset of Oracle Service Bus accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Service Bus. CVSS 3.0 Base Score 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

The vulnerability identified as CVE-2017-3507 resides within Oracle Service Bus component of Oracle Fusion Middleware, specifically affecting the Web Console Design subcomponent. This flaw represents a critical security weakness that impacts multiple version streams including 12.1.3.0.0, 12.2.1.0.0, 12.2.1.1.0, and 12.2.1.2.0, making it a widespread concern across Oracle Fusion Middleware deployments. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this weakness, significantly amplifying its threat potential.
The technical nature of this vulnerability stems from insufficient authentication and authorization controls within the Web Console Design interface of Oracle Service Bus. Attackers can exploit this weakness through unauthenticated HTTP network access, bypassing normal security controls that should protect the service bus infrastructure. This flaw creates a pathway for malicious actors to gain unauthorized access to the underlying service bus operations, effectively compromising the integrity and confidentiality of the system. The vulnerability specifically targets the design console functionality, which typically provides administrative capabilities for configuring and managing service bus components.
From an operational impact perspective, successful exploitation of CVE-2017-3507 enables attackers to perform unauthorized data manipulation operations including updates, inserts, and deletes within the service bus accessible data. Additionally, the vulnerability permits unauthorized read access to sensitive data subsets, potentially exposing confidential business information or system configurations. The compromise extends to partial denial of service conditions, where attackers can disrupt service bus operations and potentially impact business continuity. The CVSS 3.0 score of 7.3 reflects the severity of these impacts across confidentiality, integrity, and availability domains, with a base score indicating high-risk vulnerability that requires immediate attention.
The security implications of this vulnerability align with CWE-287, which addresses improper authentication issues in software systems. This weakness creates a direct pathway for attackers to bypass authentication mechanisms and gain administrative privileges within the Oracle Service Bus environment. From an adversary perspective, this vulnerability maps to several ATT&CK techniques including T1190 for exploitation of remote services, T1078 for valid accounts usage, and T1499 for network disruption. Organizations utilizing affected Oracle Service Bus versions face significant risk of unauthorized access to enterprise service bus configurations and data, potentially leading to service disruption, data exfiltration, or further lateral movement within the network infrastructure.
Organizations should implement immediate mitigation strategies including applying Oracle's security patches, restricting network access to the affected service bus console, implementing network segmentation, and monitoring for unauthorized access attempts. The vulnerability's ease of exploitation makes proactive defense measures essential, as attackers can quickly compromise affected systems without requiring advanced technical skills or significant resources. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other Oracle Fusion Middleware components and ensure comprehensive protection against similar attack vectors.
