CVE-2017-10190 in Database Server
Summary
by MITRE
Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2 and 12.2.0.1. Easily exploitable vulnerability allows high privileged attacker having Create Session, Create Procedure privilege with logon to the infrastructure where Java VM executes to compromise Java VM. While the vulnerability is in Java VM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java VM. CVSS 3.0 Base Score 8.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

The vulnerability described in CVE-2017-10190 represents a critical security flaw within the Java Virtual Machine component of Oracle Database Server, affecting versions 11.2.0.4, 12.1.0.2, and 12.2.0.1. This vulnerability operates at the core execution layer of the database's Java integration capabilities, where malicious actors with specific privileges can exploit the Java VM to gain unauthorized control. The attack vector requires an attacker to possess high-privileged database access including Create Session and Create Procedure privileges, along with valid login credentials to the database infrastructure where Java VM executes. This prerequisite aligns with the CVSS 3.0 scoring system which categorizes this vulnerability as easily exploitable with a base score of 8.2, indicating high impact across confidentiality, integrity, and availability domains.
The technical implementation of this vulnerability stems from insufficient privilege controls within the Java VM execution environment, allowing attackers to escalate their privileges beyond what should be permitted by the database's security model. When exploited, the vulnerability enables attackers to completely compromise the Java VM instance, potentially leading to full system takeover. The CVSS vector (AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) demonstrates that the attack requires local access with high privileges, does not need user interaction, and can cause cascading effects that significantly impact the entire system. This vulnerability specifically relates to CWE-276, which addresses improper privileges, and falls under the ATT&CK framework's privilege escalation and defense evasion techniques.
The operational impact of CVE-2017-10190 extends far beyond the immediate Java VM compromise, as successful exploitation can result in complete system takeover and unauthorized access to sensitive database information. Attackers who successfully exploit this vulnerability can potentially access, modify, or destroy critical data, manipulate database configurations, and establish persistent access points within the organization's infrastructure. The cascading effects mentioned in the CVSS scoring indicate that this vulnerability can impact additional Oracle products and components that rely on the compromised Java VM, creating a broader attack surface. Organizations running affected Oracle Database versions face significant risk of data breaches, system downtime, and regulatory compliance violations, particularly in environments where database security is paramount. The vulnerability's classification as a high-impact issue underscores the necessity for immediate patching and security hardening measures.
Mitigation strategies for CVE-2017-10190 should prioritize immediate patch application from Oracle's security advisories, ensuring that all affected database versions receive the appropriate security updates. Organizations must implement strict access controls and privilege management, limiting the number of users with Create Session and Create Procedure privileges to only those who absolutely require such permissions. Network segmentation and monitoring should be enhanced to detect unauthorized access attempts to database infrastructure. Additionally, security teams should conduct comprehensive vulnerability assessments to identify any potential exploitation attempts and implement proper logging and alerting mechanisms for Java VM activities. The remediation process must also include review and reinforcement of database security policies, ensuring that the principle of least privilege is strictly enforced across all database access points.
