CVE-2006-1084 in PHP-Stats
Summary
by MITRE
Multiple SQL injection vulnerabilities in PHP-Stats 0.1.9.1 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the option[prefix] parameter in admin.php and other unspecified PHP scripts, and (2) the PC_REMOTE_ADDR HTTP header to click.php.

The vulnerability described in CVE-2006-1084 represents a critical security flaw in PHP-Stats version 0.1.9.1 and earlier, exposing multiple pathways for remote attackers to execute arbitrary SQL commands. This issue falls under the category of SQL injection vulnerabilities, which are among the most dangerous web application security flaws due to their potential for complete system compromise. The vulnerability affects the administrative interface and click tracking functionality of the PHP-Stats application, creating a significant attack surface that could be exploited by malicious actors without requiring authentication or privileged access.
The technical implementation of this vulnerability stems from improper input validation and sanitization within the PHP-Stats application. Attackers can manipulate the option[prefix] parameter in admin.php and other unspecified PHP scripts to inject malicious SQL payloads directly into the database query execution chain. Additionally, the PC_REMOTE_ADDR HTTP header in click.php provides another injection vector that bypasses typical input validation mechanisms. These attack vectors demonstrate poor secure coding practices where user-supplied data is directly concatenated into SQL queries without proper parameterization or escaping mechanisms. The vulnerability is particularly concerning because it allows attackers to execute commands at the database level, potentially leading to data theft, data modification, or complete database compromise.
The operational impact of this vulnerability extends far beyond simple data exposure, as it provides attackers with the capability to manipulate the application's underlying database structure and content. Successful exploitation could result in unauthorized access to sensitive user information, modification of statistical data, or even complete database takeover. The vulnerability affects the entire PHP-Stats ecosystem, potentially compromising all statistical tracking and administrative functionalities. Organizations using affected versions of PHP-Stats face significant risk of data breaches and system compromise, as the attack requires no specialized tools beyond basic web exploitation techniques. This vulnerability directly maps to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields for execution by the database, and aligns with ATT&CK technique T1190 which describes the exploitation of vulnerabilities in web applications.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The most effective immediate solution involves upgrading to a patched version of PHP-Stats that properly implements input validation and parameterized queries. Organizations should implement proper input sanitization techniques, including the use of prepared statements and parameterized queries to prevent SQL injection attacks. Additionally, implementing web application firewalls and input validation rules at the network level can provide additional protection layers. Regular security auditing and code review processes should be established to identify similar vulnerabilities in other applications. The remediation process should include disabling unnecessary HTTP headers and implementing proper access controls to limit the attack surface. Organizations must also establish incident response procedures to quickly address any exploitation attempts and ensure that all systems are properly updated to prevent similar vulnerabilities from occurring in the future.
