The CVE-2010-4950 vulnerability represents a critical sql injection flaw within the Event extension for TYPO3 content management system. This vulnerability specifically affects versions prior to 0.3.7 and exposes the system to remote code execution through sql command injection attacks. The vulnerability stems from inadequate input validation and sanitization within the event extension module, creating an exploitable pathway for malicious actors to manipulate database queries. The flaw allows attackers to inject malicious sql payloads that can be executed with the privileges of the database user associated with the TYPO3 installation. This type of vulnerability falls under the common weakness enumeration category of CWE-89 sql injection, which is classified as a high severity issue in the owasp top ten security risks. The attack surface is particularly concerning as it enables unauthorized users to potentially extract sensitive data, modify database contents, or even escalate privileges within the affected system.
The technical implementation of this vulnerability occurs when the Event extension fails to properly sanitize user-supplied input before incorporating it into sql queries. Attackers can exploit this weakness by crafting malicious input parameters that are then processed by the vulnerable extension without adequate validation. The unspecified vectors mentioned in the description suggest that multiple input points within the extension could be exploited, including form fields, url parameters, or api endpoints that handle event-related data. This broad attack surface increases the likelihood of successful exploitation and makes the vulnerability particularly dangerous for organizations running affected TYPO3 installations. The vulnerability is especially problematic because it allows for arbitrary sql command execution, meaning attackers can perform any operation that the database user permissions permit, potentially leading to complete system compromise.
The operational impact of CVE-2010-4950 extends beyond simple data theft to encompass full system compromise and potential data destruction. Organizations running vulnerable TYPO3 installations face significant risk of unauthorized access to sensitive information stored in the database, including user credentials, personal data, and business-critical information. The ability to execute arbitrary sql commands means attackers can manipulate the database in ways that may not be immediately apparent, potentially creating backdoors or hiding malicious activities within the system. This vulnerability can also facilitate further attacks within the network, as database credentials are often reused across different systems and applications. The risk is compounded by the fact that this vulnerability was present in widely used content management systems, making it an attractive target for automated exploitation tools and increasing the potential for widespread impact across multiple organizations.
Mitigation strategies for CVE-2010-4950 primarily focus on immediate patching and implementation of proper input validation measures. The most effective solution is to upgrade the Event extension to version 0.3.7 or later, which contains the necessary security fixes to prevent sql injection attacks. Organizations should also implement proper parameterized queries and input sanitization techniques to prevent similar vulnerabilities in other parts of their applications. Security best practices recommend implementing web application firewalls and intrusion detection systems to monitor for suspicious sql injection attempts. Additionally, organizations should conduct regular security assessments and vulnerability scanning to identify potential sql injection vulnerabilities in their systems. The remediation process should include thorough testing to ensure that the patch does not introduce any compatibility issues with existing functionality. Organizations should also consider implementing database activity monitoring and access controls to limit the potential damage from successful exploitation attempts. This vulnerability highlights the importance of maintaining up-to-date security patches and following secure coding practices to prevent sql injection attacks that can lead to complete system compromise.
