The vulnerability identified as CVE-2015-1405 represents a critical SQL injection flaw within the Content Rating Extbase extension for TYPO3 CMS versions 2.0.3 and earlier. This vulnerability falls under the CWE-89 category, which specifically addresses SQL injection attacks where untrusted data is incorporated into SQL commands without proper sanitization or validation. The Content Rating Extbase extension serves as a core component for managing content ratings within TYPO3 installations, making this vulnerability particularly concerning for organizations relying on the platform for content management and web publishing.
The technical implementation of this vulnerability stems from insufficient input validation and parameter sanitization within the extension's database query construction mechanisms. Attackers can exploit this weakness by crafting malicious input that gets directly incorporated into SQL statements executed against the underlying database. The unspecified vectors suggest that multiple entry points within the extension could potentially be leveraged, including form submissions, URL parameters, or API endpoints that process user-provided data. This lack of specificity in the vulnerability description indicates a broad attack surface where various user interactions could be manipulated to achieve unauthorized database access.
The operational impact of this vulnerability extends beyond simple data theft, as remote attackers could execute arbitrary SQL commands with the privileges of the database user account. This capability allows for complete database compromise including data exfiltration, data modification, unauthorized user account creation, and potential privilege escalation within the database system. Organizations utilizing affected TYPO3 versions face significant risk of unauthorized access to sensitive content, user credentials, and business-critical data stored within their database infrastructure. The vulnerability essentially provides attackers with a backdoor into the database layer, bypassing traditional application-level security controls.
Mitigation strategies for CVE-2015-1405 primarily focus on immediate remediation through version updates to the Content Rating Extbase extension. Organizations should upgrade to version 2.0.4 or later where the SQL injection vulnerability has been addressed through proper input validation and parameterized query construction. Additionally, implementing proper input sanitization measures, employing prepared statements for all database interactions, and conducting regular security audits of third-party extensions can prevent similar vulnerabilities from emerging. Network-level protections such as web application firewalls and database activity monitoring systems can provide additional defense-in-depth measures. The ATT&CK framework categorizes this vulnerability under the T1190 technique for exploiting vulnerabilities in web applications, emphasizing the importance of maintaining up-to-date software components and implementing robust security controls to prevent exploitation of known vulnerabilities.
