The CVE-2008-3055 vulnerability represents a critical SQL injection flaw within the TYPO3 content management system's ext_tbl extension version 0.0.102 and earlier. This vulnerability resides in the Support view component of the extension, specifically affecting the database interaction layer where user input is not properly sanitized before being incorporated into SQL query constructions. The flaw enables malicious actors to manipulate database queries through unspecified attack vectors, potentially leading to unauthorized data access, modification, or complete database compromise. The vulnerability demonstrates a classic lack of input validation and proper parameterization in database operations, which falls under the common weakness enumeration CWE-89 for SQL injection vulnerabilities.
The technical exploitation of this vulnerability occurs when remote attackers can inject malicious SQL code through parameters that are processed by the ext_tbl extension's Support view functionality. Attackers can craft specially formatted input that gets directly embedded into SQL statements without proper sanitization or parameter binding mechanisms. This allows them to manipulate the intended query execution flow, potentially extracting sensitive information from the database, modifying or deleting records, or even gaining administrative access to the underlying database system. The unspecified vectors suggest that multiple input points within the extension's support functionality could be exploited, making the vulnerability particularly dangerous as it may be accessible through various attack surfaces within the TYPO3 environment.
The operational impact of CVE-2008-3055 extends beyond simple data theft, as it can enable complete system compromise when attackers leverage the SQL injection capabilities. Organizations running vulnerable TYPO3 installations become susceptible to data breaches, where sensitive customer information, user credentials, and business data could be exposed to unauthorized parties. The vulnerability also poses risks to system availability through potential database corruption or denial of service conditions that could arise from malicious query execution. Additionally, the compromise of database integrity can lead to persistent backdoors or unauthorized access to administrative functions within the TYPO3 system. This vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol manipulation and T1566 for credential access through database exploitation.
Mitigation strategies for CVE-2008-3055 primarily focus on immediate patching and code-level remediation. Organizations should upgrade to the latest version of the ext_tbl extension where the SQL injection vulnerability has been addressed through proper input validation and parameterized queries. System administrators should implement proper input sanitization measures and ensure that all user-supplied data is properly escaped or parameterized before database interaction. Database access controls should be reviewed and restricted to minimize potential damage from successful exploitation attempts. Network-level protections such as web application firewalls can provide additional layers of defense, though they should not be relied upon as the sole mitigation strategy. Security monitoring should be enhanced to detect anomalous database query patterns that might indicate exploitation attempts. The vulnerability's classification as a critical risk warrants immediate attention from security teams, with comprehensive vulnerability assessments conducted across all TYPO3 installations to identify and remediate similar issues within the broader application ecosystem.
