CVE-2023-21936 in JD Edwards EnterpriseOne Tools
Summary
by MITRE • 04/18/2023
Vulnerability in the JD Edwards EnterpriseOne Tools product of Oracle JD Edwards (component: Web Runtime SEC). Supported versions that are affected are Prior to 9.2.7.3. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise JD Edwards EnterpriseOne Tools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in JD Edwards EnterpriseOne Tools, 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 JD Edwards EnterpriseOne Tools accessible data as well as unauthorized read access to a subset of JD Edwards EnterpriseOne Tools accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2023-21936 resides within the JD Edwards EnterpriseOne Tools product, specifically within the Web Runtime SEC component of Oracle JD Edwards. This security flaw affects versions prior to 9.2.7.3, representing a significant concern for organizations utilizing this enterprise resource planning platform. The vulnerability classification as easily exploitable indicates that attackers with minimal technical expertise can leverage this weakness, particularly targeting the web runtime environment that serves as a critical interface for enterprise applications. The affected system components operate within a complex enterprise ecosystem where multiple applications and services interconnect, amplifying the potential impact beyond the immediate vulnerable component.
The technical nature of this vulnerability stems from insufficient access controls and authentication mechanisms within the web runtime environment. Attackers with low privileges and network access via HTTP can exploit this weakness to gain unauthorized access to the system's data management functions. The CVSS 3.1 base score of 5.4 reflects the moderate severity of the vulnerability, with confidentiality and integrity impacts rated as low. However, the scope change aspect of this vulnerability means that successful exploitation can extend beyond the primary target to impact additional products within the JD Edwards ecosystem. This characteristic aligns with ATT&CK technique T1078.004, which covers valid accounts and credential access, as the vulnerability likely involves exploitation of legitimate access mechanisms.
The operational impact of CVE-2023-21936 manifests through unauthorized data manipulation capabilities that allow attackers to update, insert, or delete information within the affected system. Additionally, the vulnerability enables unauthorized read access to specific subsets of accessible data, potentially exposing sensitive business information. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing approaches might be necessary to initiate the attack vector, although the actual exploitation occurs through the web runtime component. This human interaction factor corresponds to ATT&CK technique T1566, which encompasses social engineering tactics. The vulnerability's impact on the broader JD Edwards ecosystem means that compromise of one component can potentially lead to cascading effects across multiple interconnected applications and data sources.
Organizations should prioritize immediate patching of affected systems to address this vulnerability, as the CVSS vector indicates that exploitation requires low attack complexity and can result in significant data integrity compromises. The vulnerability's classification under CWE 284, which deals with improper access control, highlights the fundamental security weakness in the access control implementation within the web runtime environment. Mitigation strategies should include network segmentation to limit access to the affected web runtime services, implementation of additional authentication layers, and comprehensive monitoring of access patterns to detect anomalous behavior. Security teams should also conduct thorough assessments of the scope change impact across all connected JD Edwards applications to understand potential secondary effects of exploitation. Regular vulnerability assessments and penetration testing should be implemented to identify similar access control weaknesses that might exist within the broader enterprise environment, particularly focusing on web application interfaces and runtime environments that handle sensitive data processing operations.
