CVE-2017-10282 in Oracle
Summary
by MITRE
Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 12.1.0.2 and 12.2.0.1. Easily exploitable vulnerability allows high privileged attacker having Create Session, Execute Catalog Role privilege with network access via Oracle Net to compromise Core RDBMS. While the vulnerability is in Core RDBMS, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Core RDBMS. CVSS 3.0 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

The vulnerability identified as CVE-2017-10282 resides within Oracle Database Server's Core RDBMS component, representing a critical security flaw that affects specific version releases including 12.1.0.2 and 12.2.0.1. This vulnerability operates under the Common Weakness Enumeration framework as a weakness related to insufficient privileges and improper access control mechanisms, specifically categorized under CWE-284 which addresses improper access control. The flaw manifests as an easily exploitable condition that requires only a high-privileged attacker possessing Create Session and Execute Catalog Role privileges along with network access through Oracle Net protocol to successfully compromise the affected database system.
The technical implementation of this vulnerability exploits the underlying architecture of Oracle's network protocol handling within the RDBMS core, where insufficient validation occurs during certain database operations that process network requests. Attackers leveraging this vulnerability can execute malicious code that ultimately leads to complete takeover of the Core RDBMS functionality, as indicated by the CVSS 3.0 base score of 9.1 which reflects high impacts across confidentiality, integrity, and availability domains. The attack vector requires network access via Oracle Net protocol, making it particularly dangerous in environments where database servers are accessible over networks, and the low attack complexity combined with high privilege requirements creates a significant risk profile.
The operational impact of successful exploitation extends beyond the immediate Core RDBMS component, potentially causing cascading effects that compromise additional Oracle products within the same ecosystem. This interconnected vulnerability demonstrates the importance of understanding how database security flaws can propagate across integrated systems, particularly in enterprise environments where Oracle Database Server often serves as a foundational component for multiple applications and services. The compromise of Core RDBMS through this vulnerability can result in complete data breaches, system availability disruption, and unauthorized modification of database contents, making it a critical target for threat actors seeking to establish persistent access within enterprise networks.
Security practitioners should implement immediate mitigations including applying Oracle's official patches and updates released specifically for this vulnerability, which typically address the underlying privilege validation issues and strengthen network protocol handling within the database server. Network segmentation and firewall rules should be enforced to limit unnecessary network access to Oracle Database servers, while privilege management should be strictly enforced to ensure that only necessary database users possess the Create Session and Execute Catalog Role privileges. The ATT&CK framework categorizes this vulnerability under privilege escalation techniques, specifically targeting database server compromise through network-based attacks that leverage existing database access rights to achieve full system control, making it essential for organizations to monitor and remediate such vulnerabilities promptly to prevent potential data breaches and system compromise.
