CVE-2021-2015 in Workflow
Summary
by MITRE • 01/20/2021
Vulnerability in the Oracle Workflow product of Oracle E-Business Suite (component: Worklist). Supported versions that are affected are 12.2.3-12.2.10. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Workflow. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Workflow, 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 Workflow accessible data as well as unauthorized update, insert or delete access to some of Oracle Workflow accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2021-2015 represents a critical security flaw within Oracle E-Business Suite's Workflow component, specifically affecting versions 12.2.3 through 12.2.10. This weakness resides in the Worklist functionality of Oracle Workflow, which serves as a central mechanism for task assignment and workflow management within the enterprise resource planning system. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous in production environments where such systems handle sensitive business data and processes.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Oracle Workflow component, allowing unauthenticated attackers to access workflow functionalities through standard HTTP network connections. This flaw operates at the application layer and can be exploited without requiring prior authorization or credentials, significantly broadening the attack surface. The CVSS 3.1 score of 8.2 reflects the severity of impact, with high confidentiality implications and low integrity impact, indicating that successful exploitation could lead to unauthorized access to critical data or complete access to all Oracle Workflow accessible data. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or user manipulation might be necessary to trigger the exploit, though the underlying technical flaw remains accessible to network-based attacks.
The operational impact of this vulnerability extends beyond the immediate Oracle Workflow component, potentially affecting additional Oracle products within the E-Business Suite ecosystem. This cascading effect occurs because Oracle Workflow often integrates with other modules and systems, creating a ripple effect of potential compromise across the enterprise platform. Attackers who successfully exploit this vulnerability could gain unauthorized update, insert, or delete access to sensitive workflow data, potentially disrupting business processes and compromising the integrity of workflow-based business operations. The ability to access critical data and perform unauthorized modifications creates significant risk for organizations relying on workflow automation for business-critical processes such as procurement, approval workflows, and financial processing.
Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, particularly under the techniques related to credential access and privilege escalation, as the flaw enables unauthorized access to workflow data that may contain sensitive business information. The vulnerability aligns with CWE-287, which addresses improper authentication issues, and represents a classic case of insufficient authentication controls in enterprise applications. Organizations should implement immediate mitigations including network segmentation to restrict access to Oracle Workflow components, implementing additional authentication layers, and ensuring that all affected systems are patched according to Oracle's security advisories. Regular monitoring of workflow activities and user access logs should be enhanced to detect potential exploitation attempts, while security teams should also consider implementing network-based intrusion detection systems to identify and block suspicious HTTP traffic targeting Oracle Workflow endpoints.
