CVE-2018-3179 in Identity Manager
Summary
by MITRE
Vulnerability in the Oracle Identity Manager component of Oracle Fusion Middleware (subcomponent: Advanced Console). Supported versions that are affected are 11.1.2.3.0 and 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Identity Manager. While the vulnerability is in Oracle Identity Manager, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Identity Manager accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Identity Manager. CVSS 3.0 Base Score 7.2 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L).

The vulnerability identified as CVE-2018-3179 resides within Oracle Identity Manager's Advanced Console subcomponent of Oracle Fusion Middleware, representing a critical security weakness that affects specifically version 11.1.2.3.0 and 12.2.1.3.0. This flaw manifests as an easily exploitable vulnerability that permits unauthenticated attackers to gain network-level access through HTTP protocols, effectively bypassing authentication mechanisms that should normally protect sensitive identity management systems. The vulnerability's classification as a network-based attack vector with low attack complexity and no privilege requirements makes it particularly dangerous as it can be exploited by adversaries without requiring any prior access credentials or elevated privileges.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Advanced Console interface of Oracle Identity Manager. When processing HTTP requests, the system fails to properly validate user input or enforce appropriate authorization checks, creating an entry point for malicious actors to access restricted functionality. This weakness operates at the application layer where the system should enforce strict access controls but instead allows unauthorized parties to manipulate the console interface. The vulnerability's impact extends beyond the immediate Oracle Identity Manager component as it can potentially compromise additional products within the Oracle Fusion Middleware ecosystem due to shared infrastructure components and interconnected data flows.
The operational consequences of successful exploitation pose significant risks to enterprise security posture and identity management operations. Attackers can achieve unauthorized read access to sensitive data within Oracle Identity Manager, potentially gaining access to user credentials, identity attributes, and other confidential information stored within the system. Additionally, the vulnerability enables partial denial of service conditions that can disrupt legitimate user access to identity management services, impacting business operations and potentially affecting downstream applications that depend on proper identity provisioning and authentication. The CVSS 3.0 score of 7.2 reflects the severity of these impacts, with medium confidentiality and availability concerns that can escalate to more serious security incidents depending on the organization's specific implementation and data sensitivity.
Organizations affected by this vulnerability should prioritize immediate remediation through official Oracle patches and updates, as the vulnerability's ease of exploitation makes it a high-priority target for threat actors. Network segmentation and firewall rules should be implemented to restrict access to Oracle Identity Manager components until proper security updates are deployed. The vulnerability aligns with CWE-284 (Improper Access Control) and can be mapped to ATT&CK techniques involving credential access and denial of service operations. Security monitoring should focus on unusual HTTP traffic patterns and unauthorized access attempts to identity management systems, while incident response procedures should be updated to address potential exploitation of this specific vulnerability. Organizations should also consider implementing additional security controls such as web application firewalls and enhanced logging mechanisms to detect and prevent exploitation attempts.
