CVE-2017-10285 in Java SE
Summary
by MITRE
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: RMI). Supported versions that are affected are Java SE: 6u161, 7u151, 8u144 and 9; Java SE Embedded: 8u144. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 9.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

The vulnerability identified as CVE-2017-10285 represents a critical remote code execution flaw within Oracle Java SE and Java SE Embedded platforms, specifically affecting the Remote Method Invocation (RMI) component. This vulnerability operates at the core of Java's distributed computing framework, where RMI enables objects to execute methods on remote Java Virtual Machines. The affected versions include Java SE 6u161, 7u151, 8u144, and 9, alongside Java SE Embedded 8u144, creating a substantial attack surface across multiple Java runtime environments. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based attacks without requiring authentication, making it particularly dangerous in environments where Java applications are deployed with minimal security controls.
The technical exploitation of this vulnerability occurs through the manipulation of Java's deserialization mechanism within the RMI subsystem, which allows attackers to execute arbitrary code on vulnerable systems. This flaw specifically targets the Java sandbox security model, which is designed to isolate untrusted code from the underlying system resources. The vulnerability's impact extends beyond the immediate Java environment because successful exploitation can result in complete system compromise, as indicated by the CVSS 3.0 base score of 9.6. The attack vector requires network access via multiple protocols, suggesting that various communication channels could be leveraged to deliver malicious payloads. The requirement for human interaction indicates that attackers typically need to convince users to execute malicious Java applets or Web Start applications, which aligns with common social engineering tactics in cybersecurity attacks.
The operational implications of CVE-2017-10285 are severe and multifaceted, particularly affecting environments where Java applications are deployed in client-side scenarios such as web browsers or desktop applications. Organizations running sandboxed Java Web Start applications or applets are especially vulnerable, as these deployment models rely heavily on the Java sandbox for security isolation. The vulnerability's potential to significantly impact additional products demonstrates how a single flaw in the Java runtime can create cascading security issues across interconnected systems. Attackers exploiting this vulnerability can achieve complete takeover of affected systems, potentially leading to data breaches, system compromise, and unauthorized access to sensitive information. The high confidentiality, integrity, and availability impacts reflect the comprehensive nature of the threat, where attackers can potentially access, modify, and destroy system resources.
Mitigation strategies for CVE-2017-10285 must address both immediate remediation and long-term security posture improvements. The primary recommendation involves applying the relevant Oracle security patches and updates, which specifically address the deserialization vulnerability within the RMI component. Organizations should also implement network segmentation and firewall rules to restrict access to Java-enabled systems, particularly those running vulnerable versions of the Java runtime. Disabling Java applets and Web Start applications in web browsers provides an additional layer of protection, as these deployment models are most susceptible to exploitation. The implementation of principle of least privilege and mandatory access controls can help limit the potential damage from successful exploitation attempts. Security monitoring should focus on detecting anomalous network traffic patterns and unusual Java process behavior, which could indicate exploitation attempts. Additionally, organizations should conduct comprehensive vulnerability assessments to identify all systems running affected Java versions and prioritize remediation efforts based on risk exposure and business criticality.
This vulnerability aligns with several common attack patterns documented in the MITRE ATT&CK framework, particularly those related to exploitation of remote services and privilege escalation techniques. The vulnerability's characteristics match CWE-502, which describes deserialization of untrusted data as a critical weakness that can lead to remote code execution. Organizations should consider implementing security controls that align with the NIST Cybersecurity Framework, focusing on the protection of system components and the implementation of continuous monitoring processes. The vulnerability also demonstrates how weaknesses in core platform components can create widespread impact across enterprise environments, highlighting the importance of maintaining up-to-date security patches and implementing robust security governance processes. Regular security assessments and penetration testing should include evaluation of Java runtime environments to identify potential exploitation vectors and ensure that security controls remain effective against evolving threats.
