The vulnerability identified as CVE-2006-1847 represents a critical SQL injection flaw within the Your_Account module of PHP-Nuke version 7.8. This security weakness specifically manifests in the Your_Home functionality where the user_id parameter fails to properly sanitize input data. The flaw allows remote attackers to inject malicious SQL commands through crafted user_id values, potentially enabling unauthorized access to the underlying database system. The vulnerability stems from inadequate input validation and parameter handling within the application's database interaction layer, creating an exploitable pathway for malicious actors to manipulate database queries.
This SQL injection vulnerability directly maps to CWE-89, which classifies SQL injection as a weakness where untrusted data is incorporated into SQL queries without proper sanitization or parameterization. The attack vector operates through the web application's interface where user_id parameters are processed, allowing attackers to construct malicious SQL statements that bypass authentication mechanisms and execute unauthorized database operations. The vulnerability's impact extends beyond simple data theft, as it can enable complete database compromise including data modification, deletion, or unauthorized access to sensitive user information stored within the PHP-Nuke system.
From an operational perspective, this vulnerability presents a significant risk to organizations using PHP-Nuke 7.8, as it allows remote code execution capabilities and database manipulation without authentication. The attack can result in complete system compromise, data loss, and potential lateral movement within network environments where the vulnerable application resides. The vulnerability's exploitability is enhanced by the fact that it requires no special privileges or authentication, making it particularly dangerous in environments where PHP-Nuke serves as a primary content management platform. The lack of proper input validation creates a persistent threat that can be exploited repeatedly by attackers.
Security mitigations for CVE-2006-1847 should focus on implementing proper parameterized queries and input sanitization throughout the application's database interaction components. Organizations should immediately upgrade to patched versions of PHP-Nuke or implement input validation filters that reject or sanitize special characters in user_id parameters. The remediation approach should align with ATT&CK technique T1190, which addresses exploitation of vulnerabilities through SQL injection attacks, requiring defensive measures such as web application firewalls, database query parameterization, and comprehensive input validation. Additionally, implementing proper access controls and database user permissions can limit the impact of successful exploitation attempts, while regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other application components.
