CVE-2007-2135 in E-Business Suite
Summary
by MITRE
The ADI_BINARY component in the Oracle E-Business Suite allows remote attackers to download arbitrary documents from the APPS.FND_DOCUMENTS table via the ADI_DISPLAY_REPORT function, when passed a certain parameter. NOTE: due to lack of details from Oracle, it is not clear whether this issue is related to other CVE identifiers such as CVE-2007-2126, CVE-2007-2127, or CVE-2007-2128.

The vulnerability identified as CVE-2007-2135 affects the Oracle E-Business Suite and specifically targets the ADI_BINARY component within the application. This weakness exists in the ADI_DISPLAY_REPORT function which is designed to handle document display operations within the suite. The vulnerability stems from insufficient input validation and access control mechanisms that allow unauthorized remote attackers to exploit the system's document handling capabilities. Security researchers have noted that the flaw enables attackers to bypass normal access controls and retrieve sensitive documents stored in the APPS.FND_DOCUMENTS table, which typically contains confidential business information and proprietary data.
The technical implementation of this vulnerability involves the manipulation of specific parameters passed to the ADI_DISPLAY_REPORT function. When certain parameter values are submitted, the system fails to properly validate the input or enforce appropriate authorization checks, allowing the attacker to specify arbitrary document identifiers that correspond to entries in the FND_DOCUMENTS table. This represents a classic privilege escalation and information disclosure vulnerability that operates at the application layer. The flaw demonstrates poor input sanitization practices and inadequate security controls that should normally prevent unauthorized access to database resources. According to CWE standards, this vulnerability aligns with CWE-20, which covers improper input validation, and CWE-284, which addresses improper access control mechanisms.
The operational impact of CVE-2007-2135 extends beyond simple data theft as it provides attackers with access to potentially sensitive business documents, financial records, and operational data that could be used for competitive advantage or further exploitation. Organizations running Oracle E-Business Suite are particularly vulnerable since the attack can be executed remotely without requiring authentication credentials, making it a severe threat vector. The vulnerability's potential for widespread impact is amplified by the fact that the APPS.FND_DOCUMENTS table often contains critical business information including contracts, reports, and other confidential materials that organizations rely on for their operations. Attackers could leverage this access to gain intelligence about business operations, financial status, or strategic initiatives, potentially leading to corporate espionage or fraud.
The remediation approach for this vulnerability requires immediate patching of the Oracle E-Business Suite components, particularly addressing the ADI_BINARY functionality and associated access controls. Organizations should implement proper input validation mechanisms to ensure that all parameters passed to the ADI_DISPLAY_REPORT function are properly sanitized and validated before processing. Network segmentation and firewall rules should be enforced to limit access to the vulnerable components, while monitoring systems should be deployed to detect anomalous access patterns to the FND_DOCUMENTS table. Additionally, implementing role-based access controls and privilege separation can help minimize the potential damage from such vulnerabilities. The ATT&CK framework categorizes this as a privilege escalation technique through application layer exploitation, while the vulnerability's nature aligns with techniques involving information gathering and data exfiltration. Organizations should also conduct thorough security assessments to identify any related vulnerabilities such as those referenced in CVE-2007-2126, CVE-2007-2127, and CVE-2007-2128 that may present similar attack surfaces and require coordinated remediation efforts.
