CVE-2017-10048 in Enterprise Repository
Summary
by MITRE
Vulnerability in the Oracle Enterprise Repository component of Oracle Fusion Middleware (subcomponent: Web Interface). Supported versions that are affected are 11.1.1.7.0 and 12.1.3.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Enterprise Repository. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Enterprise Repository, 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 Enterprise Repository accessible data as well as unauthorized update, insert or delete access to some of Oracle Enterprise Repository accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2017-10048 resides within Oracle Enterprise Repository, a component of Oracle Fusion Middleware that provides repository services for enterprise applications. This specific weakness manifests in the Web Interface subcomponent, representing a critical security gap that affects Oracle Fusion Middleware versions 11.1.1.7.0 and 12.1.3.0.0. The vulnerability's classification as easily exploitable indicates that attackers can leverage this flaw without requiring specialized tools or extensive technical knowledge, making it particularly dangerous in production environments where security controls may be insufficient. The attack vector operates through HTTP network access, eliminating the need for authentication or privileged credentials, which significantly broadens the potential attack surface.
The technical nature of this vulnerability stems from inadequate access controls within the web interface component, allowing unauthenticated attackers to gain unauthorized access to sensitive repository data. According to CVSS 3.0 scoring methodology, the vulnerability carries a base score of 8.2, reflecting high confidentiality impact and moderate integrity impact, with no availability impact. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates network-based exploitation with low attack complexity, no privilege requirements, and requires user interaction from someone other than the attacker. This user interaction requirement suggests that while the vulnerability is accessible to remote attackers, successful exploitation may depend on social engineering or other indirect means of engagement. The security impact extends beyond the immediate component, potentially affecting additional Oracle products within the ecosystem through cascading effects.
Operational impacts of CVE-2017-10048 are severe and multifaceted, potentially enabling attackers to achieve complete access to all data accessible through Oracle Enterprise Repository. The vulnerability permits unauthorized update, insert, or delete operations on repository data, creating opportunities for data manipulation, corruption, or complete data loss. This comprehensive access capability aligns with CWE-284 (Improper Access Control) and represents a significant deviation from proper security boundaries that should protect enterprise data repositories. Organizations utilizing affected Oracle Fusion Middleware versions face substantial risk of data breaches, regulatory compliance violations, and operational disruptions. The vulnerability's potential to impact additional products demonstrates the interconnected nature of enterprise middleware components, where a single security flaw can create cascading effects throughout the technology stack. The requirement for human interaction introduces an element of social engineering risk, where attackers might exploit user trust to facilitate successful exploitation.
Mitigation strategies for CVE-2017-10048 should prioritize immediate patching of affected Oracle Fusion Middleware versions to address the underlying access control deficiencies. Organizations must implement network segmentation and firewall rules to restrict HTTP access to Oracle Enterprise Repository components, particularly in environments where the vulnerability cannot be immediately patched. The implementation of additional authentication layers, such as SSL/TLS encryption with certificate-based authentication, can provide supplementary protection against unauthorized access attempts. Security monitoring should be enhanced to detect unusual access patterns or attempts to exploit the web interface component, with particular attention to log analysis for unauthorized data access or modification activities. Regular vulnerability assessments and penetration testing should be conducted to identify similar access control weaknesses within the broader Oracle Fusion Middleware ecosystem. According to ATT&CK framework, this vulnerability maps to T1078 (Valid Accounts) and T1046 (Network Service Scanning) techniques, as attackers may leverage the compromised repository to establish persistent access or conduct reconnaissance activities. Organizations should also consider implementing principle of least privilege access controls and regular security audits to prevent exploitation of similar vulnerabilities in other Oracle components.
