The vulnerability identified as CVE-2006-2123 affects Network Administration Visualized (NAV) versions prior to 3.0.1, specifically targeting the report interface component. This represents a critical security flaw that enables remote attackers to execute arbitrary SQL commands through unspecified attack vectors within the reporting functionality. The vulnerability falls under the category of SQL injection attacks, which have been classified as CWE-89 by the CWE database and are systematically tracked in the MITRE ATT&CK framework under the technique T1190 for exploitation of remote services. The affected NAV version demonstrates a fundamental lack of input validation and proper sanitization of user-supplied data within the report generation interface.
The technical flaw manifests when the application fails to properly sanitize or escape user input before incorporating it into SQL queries executed against the underlying database. Attackers can exploit this weakness by injecting malicious SQL code through the report interface parameters, potentially allowing them to bypass authentication mechanisms, extract sensitive data, modify database contents, or even gain complete control over the database server. The unspecified nature of the attack vectors suggests that multiple entry points within the report interface may be vulnerable, making the exploitation surface broader than initially apparent. This type of vulnerability typically occurs when developers assume that input will always follow expected patterns without implementing proper validation or parameterized query mechanisms.
The operational impact of this vulnerability is severe for organizations relying on NAV for network administration and monitoring. Remote attackers could potentially access confidential network information, user credentials, system configurations, and other sensitive data stored within the database. The ability to execute arbitrary SQL commands provides attackers with extensive capabilities to manipulate the database content, potentially leading to data corruption, unauthorized access to network resources, or complete system compromise. Organizations using NAV versions prior to 3.0.1 face significant risk of data breaches and unauthorized system access, particularly in environments where network administrators have elevated privileges. The vulnerability could be exploited by attackers with minimal technical expertise, making it particularly dangerous in production environments.
The recommended mitigation strategy involves immediate upgrade to NAV version 3.0.1 or later, which includes proper input validation and SQL injection prevention measures. Organizations should also implement additional security controls such as database query parameterization, input sanitization, and proper access controls for the report interface. Network administrators should conduct thorough security assessments to identify any potential exploitation attempts and implement database activity monitoring to detect suspicious SQL queries. The vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol, where attackers leverage web application vulnerabilities to execute malicious SQL commands. Organizations should also consider implementing web application firewalls and regular security patch management processes to prevent similar vulnerabilities in other components of their network infrastructure.
