CVE-2020-14552 in WebCenter Portal
Summary
by MITRE
Vulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Security Framework). Supported versions that are affected are 11.1.1.9.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebCenter Portal. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Portal, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Portal accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).

The vulnerability identified as CVE-2020-14552 resides within Oracle WebCenter Portal's Security Framework component, representing a significant security weakness that affects multiple versions including 11.1.1.9.0, 12.2.1.3.0, and 12.2.1.4.0 of the Fusion Middleware suite. This vulnerability operates at the intersection of network-based attacks and privilege escalation scenarios, where a low-privileged attacker can leverage HTTP network access to compromise the targeted system. The CVSS 3.1 scoring of 6.8 indicates a moderate to high severity threat level, with particular emphasis on confidentiality impacts that could lead to unauthorized access to sensitive data or complete data exposure within the WebCenter Portal environment.
The technical nature of this vulnerability stems from insufficient security controls within the WebCenter Portal's authentication and authorization mechanisms, allowing malicious actors to bypass normal access restrictions through carefully crafted HTTP requests. The attack requires human interaction from users other than the attacker, suggesting that the exploitation might involve social engineering elements or targeted user actions that facilitate the security breach. This characteristic places the vulnerability in the CWE-284 category, which addresses improper access control issues, and aligns with ATT&CK technique T1078 for Valid Accounts and T1566 for Phishing. The security framework's failure to properly validate user permissions and session management creates a pathway for unauthorized data access that could extend beyond the immediate WebCenter Portal component to affect related Oracle Fusion Middleware products.
The operational impact of this vulnerability extends far beyond the immediate WebCenter Portal environment, as successful exploitation can result in unauthorized access to critical data or complete access to all data accessible through the portal. This comprehensive access capability places organizations at risk of data breaches, intellectual property theft, and potential regulatory compliance violations. The vulnerability's ability to significantly impact additional products demonstrates the interconnected nature of Oracle Fusion Middleware components and highlights the importance of holistic security assessments. Organizations utilizing these affected versions face potential exposure to sophisticated attack campaigns where the initial compromise could serve as a foothold for broader system infiltration, making this vulnerability particularly concerning for enterprises with extensive Oracle deployments.
Mitigation strategies should prioritize immediate patch deployment through Oracle's security updates, which address the underlying access control flaws in the Security Framework. Network segmentation and firewall rules should be implemented to restrict HTTP access to the WebCenter Portal components, while monitoring systems should be enhanced to detect anomalous access patterns that might indicate exploitation attempts. Regular security assessments and penetration testing should be conducted to identify additional vulnerabilities within the Fusion Middleware environment, with particular attention to privilege escalation paths and session management weaknesses. The implementation of multi-factor authentication and enhanced user access controls can provide additional layers of protection, while security awareness training for administrators and end-users can help prevent the social engineering components that may facilitate exploitation. Organizations should also consider implementing database activity monitoring and audit logging to track access to sensitive data and detect potential unauthorized access attempts that could result from this vulnerability.
