CVE-2018-3146 in iLearning
Summary
by MITRE
Vulnerability in the Oracle iLearning component of Oracle iLearning (subcomponent: Learner Administration). Supported versions that are affected are 6.1 and 6.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle iLearning. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iLearning, 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 iLearning accessible data as well as unauthorized update, insert or delete access to some of Oracle iLearning 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:H/I:L/A:N).

The vulnerability identified as CVE-2018-3146 resides within Oracle iLearning's Learner Administration subcomponent, affecting versions 6.1 and 6.2 of the Oracle iLearning platform. This represents a critical security flaw that exposes organizations to significant risk through unauthorized access to sensitive educational data and system manipulation capabilities. The vulnerability's classification as easily exploitable indicates that attackers can leverage standard network-based attack vectors without requiring specialized tools or extensive technical expertise to initiate successful compromise attempts.
The technical implementation of this vulnerability stems from inadequate authentication mechanisms within the Learner Administration functionality, allowing unauthenticated attackers to exploit HTTP network access points to gain unauthorized system access. This flaw operates through a combination of insufficient input validation and weak session management protocols that fail to properly verify user credentials or authorization levels before granting access to sensitive data repositories. The vulnerability's CVSS 3.0 base score of 8.2 reflects its substantial impact potential, particularly given the high confidentiality and integrity implications that can result from unauthorized data access or modification.
Operational impact assessment reveals that successful exploitation of CVE-2018-3146 can lead to comprehensive data breaches affecting all accessible Oracle iLearning information systems. Attackers may achieve unauthorized access to critical educational data including student records, learning progress information, and administrative configurations. The vulnerability also enables unauthorized update, insert, or delete operations against specific data sets within the Oracle iLearning environment, potentially causing significant disruption to educational management systems and compromising the integrity of learning administration processes. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing attacks may be necessary to initiate the exploitation sequence.
Security controls and mitigation strategies should focus on immediate network-level protections including firewall restrictions to limit HTTP access to Oracle iLearning components, implementation of robust authentication mechanisms, and comprehensive network monitoring to detect unauthorized access attempts. Organizations should also consider deploying intrusion detection systems specifically configured to identify suspicious HTTP traffic patterns associated with this vulnerability. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates that while network access is required, the attack complexity is low, and human interaction is needed, making this vulnerability particularly dangerous as it can affect multiple products beyond the immediate Oracle iLearning environment.
This vulnerability aligns with CWE-287 (Improper Authentication) and represents a significant concern for organizations implementing Oracle iLearning solutions in educational environments where data protection and privacy regulations such as FERPA or GDPR compliance are critical requirements. The attack surface extends beyond the immediate Oracle iLearning platform, potentially affecting interconnected systems through the cascading impact of unauthorized data access and modification operations. Organizations must implement immediate patch management procedures and conduct comprehensive security assessments to identify and remediate similar authentication weaknesses across their educational technology infrastructure to prevent exploitation of this and related vulnerabilities.
