CVE-2006-5344 in Database Server
Summary
by MITRE
Multiple unspecified vulnerabilities in Oracle Spatial component in Oracle Database 8.1.7.4, 9.0.1.5, 9.2.0.7, and 10.1.0.4 have unknown impact and remote authenticated attack vectors related to (1) mdsys.sdo_3gl, aka Vuln# DB20, and (2) mdsys.sdo_cs, aka DB21. NOTE: as of 20061023, Oracle has not disputed reports from reliable third parties that DB20 is a buffer overflow in GEOM_OPERATION, and DB21 is related to a buffer overflow and SQL injection in TRANSFORM_LAYER.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified as CVE-2006-5344 represents a critical security flaw within Oracle Database's Spatial component, specifically affecting versions 8.1.7.4, 9.0.1.5, 9.2.0.7, and 10.1.0.4. This vulnerability manifests through two distinct attack vectors labeled DB20 and DB21, both of which exploit weaknesses in Oracle's spatial data handling mechanisms. The spatial component is integral to Oracle Database's ability to store, query, and manipulate geographic data, making it a critical element for applications requiring location-based services and geographic information systems.
The technical implementation of these vulnerabilities involves buffer overflow conditions within the mdsys.sdo_3gl and mdsys.sdo_cs functions, which are part of Oracle's spatial data management system. DB20 specifically targets a buffer overflow in the GEOM_OPERATION function, while DB21 encompasses both buffer overflow and SQL injection vulnerabilities within the TRANSFORM_LAYER component. These flaws arise from inadequate input validation and memory management within the spatial processing routines, allowing maliciously crafted spatial data to trigger unauthorized memory access patterns. The buffer overflow conditions can potentially lead to arbitrary code execution, while the SQL injection component provides attackers with opportunities to manipulate database queries and extract sensitive information.
From an operational perspective, these vulnerabilities present significant risks to database security and integrity. The remote authenticated attack vectors mean that attackers with valid database credentials can exploit these flaws from network locations, eliminating the need for local system access. The impact extends beyond simple data corruption, as successful exploitation could lead to complete system compromise, unauthorized data access, and potential lateral movement within the database environment. Organizations utilizing Oracle Spatial functionality face heightened risk, particularly those with exposed database servers or insufficient network segmentation. The vulnerabilities align with CWE-121, which addresses stack-based buffer overflow conditions, and CWE-89, covering SQL injection flaws, both of which are fundamental security weaknesses that have historically led to severe exploitation scenarios.
The attack surface for these vulnerabilities is particularly concerning given the widespread use of Oracle Database across enterprise environments. Attackers could leverage these flaws to execute malicious code with the privileges of the database user, potentially escalating to system-level access depending on the database configuration and underlying operating system permissions. The combination of buffer overflow and SQL injection capabilities creates multiple exploitation pathways, making the vulnerability particularly dangerous as defenders must address both attack vectors simultaneously. Organizations should consider implementing network-level protections such as firewalls and intrusion detection systems to limit access to database ports and services, while also ensuring that database accounts maintain the principle of least privilege. The vulnerability also maps to several ATT&CK techniques including T1071.004 for application layer protocols and T1210 for exploitation of remote services, highlighting the multi-faceted nature of the threat landscape.
Mitigation strategies should focus on immediate patching of affected Oracle Database versions, as Oracle would have released security patches addressing these specific buffer overflow and SQL injection vulnerabilities. Database administrators should also implement comprehensive monitoring for unusual spatial data processing activities and establish strict input validation procedures for all spatial data entering the database system. Network segmentation and access controls should be enforced to limit the potential impact of successful exploitation attempts. Additionally, organizations should conduct thorough vulnerability assessments to identify any other potentially affected systems or applications that might interact with the vulnerable Oracle Spatial components, ensuring that the entire attack surface remains protected against similar exploitation techniques.
