The CVE-2008-3054 vulnerability represents a critical SQL injection flaw within the Branchenbuch extension for TYPO3 content management system, specifically affecting versions 0.8.1 and earlier. This vulnerability resides within the Yellow Pages extension which is commonly used for business directory functionality within TYPO3 websites. The flaw allows remote attackers to inject malicious SQL commands through unspecified input vectors, potentially compromising the entire database infrastructure. The vulnerability classification aligns with CWE-89 which specifically addresses SQL injection vulnerabilities where untrusted data is incorporated into SQL queries without proper sanitization or parameterization. This type of vulnerability falls under the ATT&CK framework's T1190 technique for exploitation of remote services, where attackers leverage insecure input handling to execute arbitrary commands.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the Branchenbuch extension's database interaction code. When users interact with the yellow pages functionality, the extension processes user-provided parameters through SQL queries without proper escaping or parameter binding mechanisms. Attackers can exploit this by crafting malicious input that gets directly embedded into database queries, allowing them to manipulate the SQL execution flow. The unspecified vectors suggest that multiple input points within the extension could be exploited, including search parameters, category selections, or other user input fields that are processed by the vulnerable database layer.
The operational impact of this vulnerability is severe and multifaceted for affected TYPO3 installations. Remote attackers can potentially execute arbitrary SQL commands which may lead to complete database compromise, data exfiltration, or unauthorized access to sensitive business information stored in the yellow pages directory. Depending on the database permissions, attackers might escalate privileges to gain access to other system resources or even achieve code execution on the web server. The vulnerability affects not only the integrity of business directory data but also poses risks to the broader website security posture, as database compromises often serve as entry points for further attacks. Organizations using TYPO3 with the vulnerable Branchenbuch extension face significant risk of data breaches and potential system compromise.
Mitigation strategies for CVE-2008-3054 should prioritize immediate patching of the Branchenbuch extension to version 0.8.2 or later, which contains the necessary security fixes. System administrators should implement input validation and sanitization measures at multiple layers, ensuring that all user-provided data undergoes proper escaping before database insertion. The implementation of prepared statements or parameterized queries should be enforced throughout the application codebase to prevent SQL injection exploitation. Network-level protections such as web application firewalls and intrusion detection systems can provide additional defense-in-depth measures. Regular security audits and vulnerability assessments should be conducted to identify similar issues in other TYPO3 extensions. Organizations should also consider implementing database access controls and monitoring to detect unauthorized database activities that may indicate exploitation attempts. The vulnerability highlights the importance of maintaining up-to-date CMS extensions and following secure coding practices as outlined in OWASP Top Ten and other industry security standards.
