The CVE-2009-3491 vulnerability represents a critical sql injection flaw within the Kinfusion SportFusion component for Joomla! versions 0.2.2 through 0.2.3. This vulnerability exists in the teamdetail action of the index.php script where the cid[0] parameter is processed without proper input validation or sanitization. The flaw allows remote attackers to manipulate the database queries by injecting malicious sql code through this parameter, potentially gaining unauthorized access to sensitive information or executing arbitrary commands on the underlying database server. This type of vulnerability falls under the common weakness enumeration CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is directly incorporated into sql commands without proper escaping or parameterization.
The technical exploitation of this vulnerability occurs when an attacker submits a crafted cid[0] parameter value that contains sql payload to the teamdetail action endpoint. The component fails to properly sanitize or escape user input before incorporating it into sql queries, creating an environment where malicious sql commands can be executed with the privileges of the web application's database user. This vulnerability enables attackers to perform various malicious activities including data extraction, modification, or deletion, depending on the database user's permissions. The attack vector is particularly dangerous as it requires no authentication and can be executed remotely, making it a significant threat to web applications running vulnerable versions of the Kinfusion SportFusion component.
The operational impact of this vulnerability extends beyond simple data compromise as it can lead to complete system takeover if the database user has elevated privileges. Attackers can leverage this vulnerability to extract sensitive user credentials, personal information, or system configuration data stored in the database. Additionally, the vulnerability can be used to inject malicious content into the web application, potentially leading to further exploitation through cross-site scripting or other chained attacks. The vulnerability also poses risks to database integrity and availability, as attackers could potentially execute destructive commands that modify or delete critical data. This type of vulnerability is particularly concerning in web application environments where database access is limited but still provides sufficient privileges for unauthorized access.
Organizations affected by this vulnerability should immediately implement several mitigation strategies to protect their systems. The primary recommendation is to upgrade to the latest version of the Kinfusion SportFusion component where the sql injection vulnerability has been patched and properly addressed. System administrators should also implement input validation and sanitization measures at the application level to prevent malicious input from reaching database queries. Additionally, database access should be restricted to the minimum required privileges for the web application to function properly, reducing the potential impact of successful exploitation. Network-based mitigations such as web application firewalls can provide additional protection by filtering suspicious sql injection patterns. This vulnerability aligns with several ATT&CK techniques including T1190 for exploit known vulnerability and T1071.004 for application layer protocol to establish persistence and maintain access to compromised systems. Regular security assessments and vulnerability scanning should be conducted to identify and remediate similar vulnerabilities in other components of the Joomla! platform or related web applications.
