CVE-2006-5340 in Database Server
Summary
by MITRE
Multiple unspecified vulnerabilities in Oracle Spatial component in Oracle Database 8.1.7.4, 9.0.1.5, 9.2.0.8, 10.1.0.5, and 10.2.0.2 have unknown impact and remote authenticated attack vectors related to (1) mdsys.sdo_lrs, aka Vuln# DB13, and (2) Vuln# DB17. NOTE: as of 20061023, Oracle has not disputed reports from reliable third parties that DB13 is related to bypassing input validation for SQL injection related to convert_to_lrs_layer and dbms_assert, and DB17 is related to SQL injection in the trigger in the SDO_DROP_USER package.

The vulnerability identified as CVE-2006-5340 represents a critical security flaw within Oracle Database's Spatial component, affecting multiple versions including 8.1.7.4, 9.0.1.5, 9.2.0.7, 10.1.0.5, and 10.2.0.2. This issue falls under the category of unspecified vulnerabilities that can be exploited through remote authenticated attack vectors, making it particularly dangerous as it requires minimal privileges to exploit. The affected Oracle Spatial component is a core part of Oracle Database's geospatial functionality, enabling spatial data management and analysis capabilities that are widely utilized in enterprise environments for mapping, location-based services, and geographic information systems.
The technical flaw manifests in two distinct vulnerability vectors designated as DB13 and DB17 within the Oracle Spatial component. DB13 specifically relates to bypassing input validation mechanisms for SQL injection attacks, particularly affecting the convert_to_lrs_layer and dbms_assert functions within the mdsys.sdo_lrs package. This vulnerability allows authenticated attackers to circumvent normal input validation checks and inject malicious SQL code, potentially leading to unauthorized data access, modification, or deletion. DB17 represents another SQL injection vulnerability found within the trigger mechanism of the SDO_DROP_USER package, which can be exploited to execute arbitrary SQL commands. Both vulnerabilities stem from inadequate input sanitization and validation processes within Oracle's spatial database functions, creating pathways for attackers to manipulate database operations through carefully crafted inputs.
The operational impact of these vulnerabilities is substantial as they enable authenticated attackers with minimal privileges to potentially gain unauthorized access to sensitive spatial data and database operations. The remote authenticated attack vector means that exploitation can occur over network connections without requiring physical access to the database server, making these vulnerabilities particularly attractive to threat actors. Organizations utilizing Oracle Spatial functionality for critical applications such as asset management, logistics tracking, or geographic information systems face significant risk from these vulnerabilities. The potential for data leakage, unauthorized modifications, and privilege escalation through these SQL injection pathways could result in substantial financial losses, regulatory compliance violations, and operational disruptions. Additionally, the widespread use of these Oracle Database versions in enterprise environments amplifies the potential impact across multiple organizations.
Mitigation strategies for CVE-2006-5340 should prioritize immediate patching of affected Oracle Database versions through official Oracle security updates. Organizations should implement network segmentation and access controls to limit exposure of database systems to untrusted networks. Database administrators should review and restrict permissions for spatial functions, particularly those related to mdsys.sdo_lrs and SDO_DROP_USER package operations. Input validation measures should be strengthened at application layers that interact with Oracle Spatial components, implementing proper parameterization and sanitization techniques to prevent SQL injection exploitation. Security monitoring should be enhanced to detect anomalous database access patterns and potential exploitation attempts. The vulnerabilities align with CWE-89 SQL Injection and CWE-20 Improper Input Validation categories, and they map to ATT&CK techniques including T1071.004 Application Layer Protocol and T1190 Exploit Public-Facing Application, highlighting the need for comprehensive defensive measures across network, application, and database security controls. Organizations should also conduct thorough vulnerability assessments to identify any custom applications or scripts that might be leveraging the affected spatial functions and ensure proper security hardening of these components.
