CVE-2018-2564 in WebCenter Content
Summary
by MITRE
Vulnerability in the Oracle WebCenter Content component of Oracle Fusion Middleware (subcomponent: Content Server). The supported version that is affected is 11.1.1.9.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Content. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Content, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle WebCenter Content accessible data as well as unauthorized read access to a subset of Oracle WebCenter Content 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:L/I:H/A:N).

The vulnerability identified as CVE-2018-2564 resides within Oracle WebCenter Content component of Oracle Fusion Middleware, specifically affecting the Content Server subcomponent. This flaw exists in version 11.1.1.9.0 and represents a critical security weakness that exposes organizations to significant risk. The vulnerability operates at the network level, requiring only HTTP access for exploitation, making it particularly dangerous as it does not require authentication credentials to initiate attacks. The CVSS 3.0 base score of 8.2 indicates a high severity classification, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:N highlighting the ease of exploitation, lack of privilege requirements, and the potential for significant impact on both confidentiality and integrity aspects of the affected system.
The technical nature of this vulnerability stems from insufficient access controls within the Oracle WebCenter Content platform, allowing unauthorized users to perform critical operations without proper authentication. Attackers can leverage this weakness to execute unauthorized actions including creating, deleting, or modifying sensitive data within the content management system. The vulnerability's impact extends beyond the immediate component as it can affect additional Oracle products within the ecosystem, creating cascading security implications. The requirement for human interaction from a person other than the attacker suggests that social engineering or user manipulation may be necessary to complete the attack chain, though this does not mitigate the overall risk level.
Operational impact of CVE-2018-2564 is substantial, as successful exploitation can lead to complete compromise of content management systems and data integrity breaches. The ability to perform unauthorized data modifications creates opportunities for data corruption, information tampering, and potential disruption of business operations. Organizations utilizing Oracle WebCenter Content may face regulatory compliance issues, data loss, and reputational damage if this vulnerability is exploited. The vulnerability's classification under CWE-284 (Improper Access Control) aligns with common security weaknesses that enable unauthorized access to system resources. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and data manipulation, potentially enabling adversaries to establish persistent access to critical content repositories.
Mitigation strategies for this vulnerability should include immediate patch application from Oracle to address the identified access control weakness. Organizations should implement network segmentation to limit access to the affected Oracle WebCenter Content servers and establish robust monitoring for unauthorized access attempts. Additional protective measures include implementing strong authentication mechanisms, regularly reviewing access controls, and conducting security assessments to identify similar weaknesses within the Oracle Fusion Middleware environment. The vulnerability's characteristics suggest that organizations should also review their incident response procedures to ensure rapid detection and remediation of potential exploitation attempts, given the critical nature of content management systems and their potential for widespread impact across enterprise environments.
