The CVE-2010-1017 vulnerability represents a critical SQL injection flaw within the SAV Filter Months extension for TYPO3 content management systems. This vulnerability specifically affects versions prior to 1.0.5 and exposes the system to remote code execution through maliciously crafted SQL commands. The vulnerability stems from inadequate input validation and sanitization within the extension's database query construction mechanisms, allowing attackers to manipulate query parameters and inject malicious SQL code. The SAV Filter Months extension, designed to filter content by month, fails to properly escape or parameterize user-supplied input before incorporating it into database queries, creating a persistent vector for exploitation.
The technical implementation of this vulnerability aligns with CWE-89, which categorizes SQL injection as a direct consequence of insufficient input sanitization in database interactions. The flaw operates by accepting user-controllable parameters through HTTP requests and directly embedding them into SQL query strings without proper validation or escaping mechanisms. Attackers can exploit this by crafting malicious input that alters the intended query structure, potentially gaining unauthorized access to database contents, modifying sensitive information, or executing administrative commands. The unspecified vectors mentioned in the description suggest that multiple input points within the extension could be compromised, making the attack surface broader than initially apparent.
The operational impact of this vulnerability extends beyond simple data theft, as it enables full database compromise and potential system takeover. Remote attackers can leverage this vulnerability to extract confidential information including user credentials, personal data, and system configurations. The attack requires no authentication and can be executed from any location, making it particularly dangerous for publicly accessible TYPO3 installations. Successful exploitation could result in complete system compromise, data exfiltration, and potential lateral movement within network environments where the vulnerable TYPO3 instance resides. Organizations running affected versions face significant risk of unauthorized access and potential regulatory violations due to data exposure.
Mitigation strategies for CVE-2010-1017 primarily involve immediate patching of the SAV Filter Months extension to version 1.0.5 or later, which includes proper input validation and parameterized query implementations. System administrators should conduct comprehensive vulnerability assessments to identify all instances of the vulnerable extension across their TYPO3 installations. Additional defensive measures include implementing web application firewalls to monitor and filter suspicious SQL patterns, disabling unnecessary extension functionality, and establishing proper input validation at multiple layers of the application stack. The remediation process should align with ATT&CK framework's T1190 technique for exploiting vulnerabilities in web applications, emphasizing the importance of patch management and input sanitization as core defensive controls. Organizations should also implement continuous monitoring solutions to detect potential exploitation attempts and maintain detailed audit logs for forensic analysis.
