CVE-2017-10352 in WebLogic Server
Summary
by MITRE
Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS - Web Services). The supported version that is affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0, 12.2.1.2.0 and 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. While the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle WebLogic Server as well as unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data and unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:H).

The vulnerability identified as CVE-2017-10352 represents a critical security flaw within Oracle WebLogic Server's Web Services component, specifically affecting multiple versions including 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0, 12.2.1.2.0, and 12.2.1.3.0. This vulnerability falls under the Common Weakness Enumeration category CWE-284, which addresses improper access control mechanisms, and specifically relates to CWE-444, which deals with improper handling of HTTP requests. The flaw resides in the WLS (Web Services) subcomponent of Oracle Fusion Middleware, making it particularly dangerous as it affects a core component of enterprise application infrastructure.
The technical nature of this vulnerability allows for highly dangerous unauthenticated remote exploitation through HTTP network access, making it exceptionally easy for attackers to exploit. The CVSS 3.0 scoring of 9.9 indicates the highest severity level, reflecting the comprehensive impact across confidentiality, integrity, and availability domains. Attackers can leverage this vulnerability to achieve complete denial of service conditions, causing either hangs or repeated crashes that effectively disable the WebLogic Server. Additionally, successful exploitation grants unauthorized capabilities to modify, insert, or delete data within the server's accessible data stores, while also providing unauthorized read access to sensitive information within the system.
The operational impact of CVE-2017-10352 extends beyond the immediate WebLogic Server compromise, as the vulnerability can significantly affect additional Oracle products within the same ecosystem. This cascading effect aligns with the ATT&CK framework's technique T1068, which covers exploit for privilege escalation, and demonstrates how a single vulnerability can create multiple attack vectors. The potential for complete system disruption through denial of service attacks makes this vulnerability particularly attractive to malicious actors seeking to disable critical enterprise services. Organizations running affected versions of Oracle WebLogic Server face substantial risk of data breaches, service interruptions, and potential regulatory compliance violations.
Mitigation strategies for this vulnerability should include immediate patching of affected Oracle WebLogic Server versions, implementation of network-level restrictions to limit HTTP access to the server, and deployment of intrusion detection systems to monitor for exploitation attempts. The vulnerability's CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:H) indicates that network-based attacks require no authentication and can be executed with low complexity, making proactive defense measures essential. Organizations should also consider implementing application firewalls, restricting unnecessary network exposure, and monitoring for suspicious HTTP requests that may indicate exploitation attempts. The vulnerability's classification as easily exploitable and the high CVSS score underscore the critical need for immediate remediation actions to protect enterprise infrastructure from potential compromise.
