CVE-2018-2828 in WebCenter Content
Summary
by MITRE
Vulnerability in the Oracle WebCenter Content component of Oracle Fusion Middleware (subcomponent: Content Server). Supported versions that are affected are 11.1.1.9.0, 12.2.1.2.0 and 12.2.1.3.0. Easily exploitable vulnerability allows low privileged 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 access to critical data or complete access to all Oracle WebCenter Content accessible data as well as unauthorized update, insert or delete access to some of Oracle WebCenter Content accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle WebCenter Content. CVSS 3.0 Base Score 8.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L).

The vulnerability identified as CVE-2018-2828 resides within Oracle WebCenter Content component of Oracle Fusion Middleware, specifically within the Content Server subcomponent. This weakness affects multiple supported versions including 11.1.1.9.0, 12.2.1.2.0, and 12.2.1.3.0, representing a significant attack surface for malicious actors targeting enterprise content management systems. The vulnerability classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to compromise the system, making it particularly dangerous in environments where security controls may be insufficient.
The technical flaw manifests as a security weakness that permits low privileged attackers with network access via HTTP protocols to compromise the Oracle WebCenter Content system. This vulnerability operates through a combination of network-based exploitation and human interaction requirements, meaning that while the initial attack vector requires network access, successful exploitation also depends on user actions beyond the attacker's direct control. The CVSS 3.0 base score of 8.2 reflects the severity of impact across confidentiality, integrity, and availability domains, with confidentiality rated as high impact, integrity as low impact, and availability as low impact, though the overall score indicates substantial risk.
Operational impact of this vulnerability extends beyond the immediate compromise of Oracle WebCenter Content itself, potentially affecting additional products within the Oracle Fusion Middleware ecosystem. Successful exploitation can result in unauthorized access to critical data within the content management system, potentially exposing sensitive corporate information, intellectual property, or confidential documents. The vulnerability also enables unauthorized modification capabilities, allowing attackers to insert, update, or delete content within the system, which could lead to data corruption, information tampering, or complete data loss. Additionally, attackers can cause partial denial of service conditions that may disrupt business operations and content accessibility for legitimate users.
The security implications of CVE-2018-2828 align with CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) categories, reflecting both inadequate access controls and potential CSRF vulnerabilities within the content server implementation. From an adversary perspective, this vulnerability maps to ATT&CK techniques including T1213.002 (Exploitation for Credential Access) and T1499.004 (Endpoint Denial of Service) when considering the partial denial of service impact. Organizations should implement immediate mitigations including patching affected systems, network segmentation to limit access to the content server, implementing robust authentication controls, and monitoring for suspicious HTTP traffic patterns. The human interaction requirement suggests that security awareness training for end users becomes critical in preventing successful exploitation through social engineering approaches that might be employed to trigger the vulnerability.
