CVE-2019-2682 in Applications Framework
Summary
by MITRE
Vulnerability in the Oracle Applications Framework component of Oracle E-Business Suite (subcomponent: Attachments / File Upload). Supported versions that are affected are 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7 and 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Applications Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Applications Framework, 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 Applications Framework accessible data as well as unauthorized update, insert or delete access to some of Oracle Applications Framework 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-2019-2682 resides within the Oracle Applications Framework component of Oracle E-Business Suite, specifically affecting the Attachments and File Upload subcomponent. This security flaw impacts multiple version ranges including 12.1.3 through 12.2.8, representing a significant attack surface for organizations utilizing Oracle EBS solutions. The vulnerability operates at the application layer and presents a critical risk due to its ease of exploitation and the potential for unauthorized access to sensitive business data. The CVSS score of 8.2 reflects the high severity of this weakness, with confidentiality and integrity impacts rated as high, while availability remains low. The attack vector requires network access via HTTP protocol, making it accessible to remote threat actors without authentication credentials.
The technical implementation flaw stems from insufficient validation and sanitization of file upload parameters within the Oracle Applications Framework. This weakness allows attackers to bypass normal access controls and potentially upload malicious files or manipulate existing file handling processes. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or targeted user engagement may be necessary to achieve successful exploitation. However, once initiated, the attack can lead to unauthorized access to critical business data, including financial records, customer information, and operational details. The impact extends beyond the immediate Oracle Applications Framework, potentially affecting other integrated products within the Oracle EBS ecosystem.
The operational implications of this vulnerability are severe for organizations relying on Oracle E-Business Suite for their core business operations. Successful exploitation could result in complete data compromise, allowing attackers to view, modify, or delete sensitive information across multiple business functions. The vulnerability's ability to impact additional products within the Oracle EBS environment creates cascading security risks that extend far beyond the initial attack surface. Organizations may experience significant financial losses, regulatory compliance violations, and reputational damage if this vulnerability is exploited. The CVSS vector indicates that while the attack requires user interaction, the potential for unauthorized access to critical data and modification of information presents a substantial risk to business continuity and data integrity.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates as released through their official security bulletins. Network segmentation and access controls should be strengthened to limit exposure of the vulnerable components. Monitoring for suspicious file upload activities and implementing robust input validation measures can help detect and prevent exploitation attempts. The vulnerability aligns with CWE-434 which describes insecure file upload vulnerabilities, and may map to ATT&CK techniques such as T1190 for exploit via web shell and T1078 for valid accounts usage. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other components of the Oracle EBS environment. Additionally, implementing web application firewalls and content delivery network protections can provide additional layers of defense against exploitation attempts targeting this specific vulnerability.
