CVE-2024-20949 in Customer Interaction History
Summary
by MITRE • 02/17/2024
Vulnerability in the Oracle Customer Interaction History product of Oracle E-Business Suite (component: Outcome-Result). Supported versions that are affected are 12.2.3-12.2.13. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Customer Interaction History. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Customer Interaction History, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Customer Interaction History accessible data as well as unauthorized read access to a subset of Oracle Customer Interaction History accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

This vulnerability resides within Oracle Customer Interaction History, a component of the Oracle E-Business Suite that tracks customer interaction data and outcomes. The flaw exists in the Outcome-Result functionality where the application fails to properly validate and authenticate incoming HTTP requests. Affected versions span from 12.2.3 through 12.2.13, representing a significant release range that indicates this issue has persisted across multiple maintenance cycles. The vulnerability is classified as easily exploitable due to its accessibility over unauthenticated network connections via HTTP protocols, making it particularly dangerous for organizations with exposed web services.
The technical nature of this flaw stems from insufficient input validation and authentication mechanisms within the Oracle Customer Interaction History component. Attackers can leverage this weakness without requiring prior authorization or credentials to establish connections and potentially manipulate customer interaction records. The CVSS 3.1 score of 6.1 reflects moderate severity with confidentiality and integrity impacts rated as low, yet the scope change aspect indicates that successful exploitation could affect additional Oracle products beyond the immediate component. This cross-product impact demonstrates how vulnerabilities in one module can create cascading security risks throughout an enterprise application ecosystem.
The operational implications of this vulnerability are substantial as it allows attackers to perform unauthorized data modifications including updates, inserts, and deletions of customer interaction history records. Additionally, the vulnerability enables unauthorized read access to sensitive customer data subsets, potentially exposing confidential customer information, interaction outcomes, and business-critical relationship data. The requirement for human interaction from individuals other than the attacker suggests that social engineering or phishing techniques might be necessary to trigger the vulnerability, though this does not mitigate the underlying security flaw. This scenario aligns with ATT&CK technique T1203 (Exploitation for Client Execution) where attackers leverage application vulnerabilities to execute malicious activities.
The attack vector AV:N indicates network-based exploitation without requiring physical access, while AC:L demonstrates that the attack can be executed with minimal technical expertise. The PR:N classification reveals that no authentication is required prior to exploitation, and UI:R shows that successful attacks depend on user interaction, typically involving clicking malicious links or visiting compromised web pages. Security professionals should consider this vulnerability in relation to CWE-287 (Improper Authentication) and CWE-352 (Cross-Site Request Forgery) which address similar authentication and session management weaknesses. Organizations should implement immediate mitigations such as network segmentation, web application firewalls, and access controls to limit exposure while planning comprehensive patching strategies for affected Oracle E-Business Suite deployments.
The scope change aspect of this vulnerability emphasizes the interconnected nature of enterprise applications where a flaw in one module can potentially compromise entire systems. This characteristic aligns with ATT&CK framework's emphasis on privilege escalation and lateral movement techniques, where initial access through a vulnerable component could enable attackers to expand their foothold within the Oracle environment. The potential for unauthorized data modification and reading creates significant business risks including customer data breaches, regulatory compliance violations, and damage to organizational reputation. Organizations should conduct thorough risk assessments and implement monitoring solutions to detect anomalous access patterns that might indicate exploitation attempts against this vulnerability.
