CVE-2020-2873 in Customer Interaction History
Summary
by MITRE
Vulnerability in the Oracle Customer Interaction History product of Oracle E-Business Suite (component: Outcome-Result). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.9. 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. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Customer Interaction History accessible data as well as unauthorized update, insert or delete access to some of Oracle Customer Interaction History 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-2020-2873 represents a critical security flaw within Oracle Customer Interaction History, a component of the Oracle E-Business Suite ecosystem. This vulnerability exists in specific version ranges including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.9, making it a widespread concern across multiple Oracle EBS releases. The flaw manifests as an easily exploitable weakness that allows unauthenticated attackers to compromise the targeted system through standard HTTP network connections, presenting a significant risk to organizations utilizing these affected versions. The vulnerability's classification as CVSS 3.0 Base Score 8.2 indicates a high severity level with substantial impacts to confidentiality and integrity, while the attack vector requires network access with low complexity and no privileges, yet demands human interaction from users other than the attacker.
The technical nature of this vulnerability stems from insufficient authentication and authorization controls within the Outcome-Result component of Oracle Customer Interaction History. Attackers can exploit this weakness to gain unauthorized access to sensitive customer interaction data, potentially compromising all accessible information within the system. The vulnerability's impact extends beyond the immediate component, as successful exploitation can affect additional Oracle products within the E-Business Suite environment, creating cascading security implications. The attack requires human interaction from legitimate users, suggesting that social engineering or targeted phishing attacks may be necessary to initiate the exploitation process, though once initiated the attacker can access critical data and potentially modify or delete information within the system.
The operational impact of this vulnerability is substantial, particularly for organizations managing customer interaction data through Oracle E-Business Suite. Successful attacks can result in unauthorized access to confidential customer information, potentially exposing sensitive personal data, business interactions, and proprietary customer relationship information. The integrity impact allows attackers to perform unauthorized updates, inserts, or deletions of data, which could compromise the accuracy and reliability of customer interaction records. Organizations may face regulatory compliance violations, data breach notifications, and potential legal consequences due to unauthorized data access. The CVSS vector indicates that while the attacker cannot directly cause availability impact, the confidentiality and integrity violations create significant business disruption and reputational damage.
Mitigation strategies for CVE-2020-2873 should prioritize immediate patching of affected Oracle E-Business Suite versions to address the authentication and authorization flaws. Organizations must implement network segmentation and access controls to limit exposure of the vulnerable component to untrusted networks. The vulnerability aligns with CWE-287, which addresses improper authentication issues, and may relate to ATT&CK techniques involving credential access and privilege escalation. Security teams should enhance monitoring for unusual access patterns and implement additional authentication layers beyond the default system controls. Regular vulnerability assessments and penetration testing should be conducted to identify similar weaknesses in other Oracle EBS components. Organizations should also establish incident response procedures specifically addressing data access violations and ensure proper user access controls are implemented to minimize the impact of potential exploitation. The vulnerability demonstrates the importance of maintaining up-to-date security patches and implementing comprehensive security monitoring across all enterprise applications.
