The CVE-2013-4745 vulnerability represents a critical SQL injection flaw within the My quiz and poll extension for TYPO3 content management system. This vulnerability affects versions prior to 2.0.6 and exposes the system to remote code execution attacks through unspecified attack vectors. The flaw resides in how the extension processes user input, creating opportunities for malicious actors to manipulate database queries and gain unauthorized access to sensitive information. The vulnerability is particularly concerning as it allows attackers to execute arbitrary SQL commands without requiring authentication, making it a severe threat to TYPO3 installations using the affected extension.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the myquizpoll extension. When user-supplied data is directly incorporated into SQL queries without proper escaping or parameterization, attackers can inject malicious SQL syntax that alters the intended query behavior. This type of vulnerability maps directly to CWE-89 which specifically addresses SQL injection flaws in software applications. The attack vectors remain unspecified in the CVE description, suggesting that multiple entry points within the extension could be exploited, potentially including form submissions, URL parameters, or API endpoints that process quiz and poll data.
From an operational perspective, the impact of this vulnerability extends beyond simple data theft to encompass full database compromise and potential system infiltration. Attackers could extract sensitive user information, modify quiz results, manipulate poll data, or even escalate privileges within the TYPO3 environment. The remote execution capability means that attackers do not need physical access to the system, allowing them to exploit the vulnerability from anywhere on the internet. This vulnerability aligns with ATT&CK technique T1071.004 which covers application layer protocol manipulation, and T1046 which involves network service scanning to identify vulnerable targets. Organizations running TYPO3 systems with the affected extension face significant risk of data breaches, service disruption, and potential regulatory compliance violations.
The recommended mitigation strategy involves immediate upgrade to version 2.0.6 or later of the myquizpoll extension, which includes proper input validation and parameterized query implementations. System administrators should also implement web application firewalls to monitor and block suspicious SQL injection patterns, conduct thorough security audits of installed extensions, and ensure that all TYPO3 installations maintain current security patches. Additional defensive measures include limiting database user privileges, implementing proper access controls, and monitoring database logs for unusual query patterns that might indicate exploitation attempts. Organizations should also consider implementing intrusion detection systems and regularly review their security configurations to prevent similar vulnerabilities from emerging in other components of their TYPO3 installations.
