CVE-2020-2819 in Universal Work Queue
Summary
by MITRE
Vulnerability in the Oracle Universal Work Queue product of Oracle E-Business Suite (component: Work Provider Administration). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Universal Work Queue. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Universal Work Queue, 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 Universal Work Queue accessible data as well as unauthorized update, insert or delete access to some of Oracle Universal Work Queue 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-2020-2819 resides within Oracle Universal Work Queue component of the Oracle E-Business Suite, specifically within the Work Provider Administration module. This flaw affects versions 12.1.1 through 12.1.3, representing a significant security weakness that exploits the product's network accessibility via HTTP protocols. The vulnerability's classification as easily exploitable indicates that attackers can leverage this weakness without requiring specialized tools or extensive technical knowledge, making it particularly dangerous in production environments where such systems are typically exposed to external networks. The CVSS 3.0 scoring system assigns a base score of 8.2, reflecting the severity of potential impacts including confidentiality and integrity breaches that could compromise critical business data.
The technical exploitation of this vulnerability requires minimal prerequisites for successful compromise, as it does not demand authentication credentials from the attacker's perspective. However, the attack vector necessitates human interaction from individuals other than the attacker, suggesting that social engineering or targeted user engagement may be required to trigger the vulnerability effectively. This characteristic aligns with ATT&CK technique T1203 - Exploitation for Client Execution, where the vulnerability serves as a gateway for unauthorized access to sensitive data within the Oracle Universal Work Queue system. The attack's impact extends beyond the immediate component, potentially affecting additional Oracle products within the E-Business Suite ecosystem, creating cascading security implications that could compromise entire business processes.
The operational consequences of successful exploitation include unauthorized access to critical data within Oracle Universal Work Queue, potentially enabling attackers to view sensitive business information, manipulate data, or execute unauthorized modifications to the system's accessible data repositories. The vulnerability's impact on confidentiality is rated as high, indicating that attackers could gain access to sensitive information that may include proprietary business data, financial records, or operational details. Integrity impacts are rated as moderate, suggesting that while attackers cannot directly cause complete system destruction, they can potentially modify or corrupt data within the work queue system. The CVSS vector specifically indicates that this vulnerability can affect multiple products within the Oracle E-Business Suite environment, demonstrating the interconnected nature of Oracle's enterprise applications and the potential for cross-component exploitation.
Security mitigations for CVE-2020-2819 should prioritize immediate patching of affected Oracle E-Business Suite versions to address the underlying flaw in the Work Provider Administration component. Organizations should implement network segmentation to limit access to Oracle Universal Work Queue systems, particularly restricting HTTP access to authorized administrative networks. The implementation of web application firewalls and intrusion detection systems can help monitor for exploitation attempts targeting this specific vulnerability. Additionally, security teams should conduct comprehensive vulnerability assessments to identify other potentially affected Oracle products within their environment, as the vulnerability's impact extends beyond the immediate component. According to CWE guidelines, this vulnerability maps to CWE-284 - Improper Access Control, specifically highlighting inadequate authorization controls within the Oracle Universal Work Queue administration interface. Organizations should also consider implementing privileged access management solutions to reduce the attack surface and ensure that administrative access to Oracle systems is strictly controlled and monitored. The vulnerability's classification under CVSS 3.0 framework demonstrates its potential for significant business impact, particularly in environments where Oracle E-Business Suite components handle sensitive financial and operational data.
