CVE-2007-2170 in E-Business Suite
Summary
by MITRE
The APPLSYS.FND_DM_NODES package in Oracle E-Business Suite does not check for valid sessions, which allows remote attackers to delete arbitrary nodes. 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-2007-2170 resides within the APPLSYS.FND_DM_NODES package of Oracle E-Business Suite, representing a critical security flaw that undermines session validation mechanisms. This weakness allows remote attackers to execute unauthorized node deletion operations without proper authentication or authorization checks. The vulnerability specifically targets the distributed processing capabilities of the Oracle E-Business Suite, where nodes represent individual processing units within the distributed architecture. The absence of session validation in this package creates an exploitable condition that bypasses normal access controls and authentication procedures that should normally govern administrative operations within the suite.
The technical implementation of this vulnerability stems from inadequate input validation and session management within the FND_DM_NODES package, which is responsible for managing distributed processing nodes in Oracle E-Business Suite environments. Attackers can leverage this flaw to perform arbitrary node deletions, potentially disrupting critical business processes and data processing workflows. The vulnerability operates at the database level where the package executes without verifying the legitimacy of the calling session, allowing malicious actors to impersonate authorized users or exploit existing legitimate sessions to perform unauthorized administrative actions. This particular flaw falls under the category of insufficient session validation, which is classified as CWE-613, and represents a direct violation of the principle of least privilege in security architecture.
The operational impact of CVE-2007-2170 extends beyond simple data integrity concerns to encompass potential business disruption and system availability issues. When attackers can delete arbitrary nodes within the distributed processing framework, they effectively compromise the stability of the entire Oracle E-Business Suite implementation. This vulnerability can lead to cascading failures where the removal of critical processing nodes results in service outages, data processing delays, and potential data loss scenarios. The attack vector is particularly concerning because it operates remotely, meaning that adversaries do not require physical access to the system or local network privileges to exploit the vulnerability. The potential for this issue to be related to other CVE identifiers such as CVE-2007-2126, CVE-2007-2127, or CVE-2007-2128 suggests a broader pattern of session validation weaknesses within the Oracle E-Business Suite that may compound the overall risk profile.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1566 for initial access through remote services, and T1485 for data destruction or system disruption. The vulnerability enables adversaries to achieve persistence and maintain access through manipulation of the distributed processing infrastructure, potentially allowing for more sophisticated attack chains. Organizations utilizing Oracle E-Business Suite should consider implementing network segmentation and access controls to limit exposure to this vulnerability, while also ensuring that proper patch management procedures are in place to address the underlying session validation issues. The lack of detailed information from Oracle regarding the relationship between this CVE and others in the same vulnerability family underscores the importance of comprehensive vulnerability assessment and the need for organizations to maintain vigilance against related security weaknesses in their Oracle implementations.
