The vulnerability identified as CVE-2006-5772 represents a critical security flaw in the FreeWebshop 2.2.1 content management system that exposes multiple pathways for remote attackers to perform SQL injection attacks. This vulnerability affects the index.php script which serves as the primary entry point for the web application, making it a high-value target for exploitation. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly filter user-supplied data before incorporating it into SQL query constructions, creating opportunities for malicious actors to manipulate database operations through crafted input parameters.
The technical implementation of this vulnerability manifests through two distinct attack vectors that exploit the same underlying weakness in input handling. The first vector targets the password parameter where attacker-controlled input can be directly injected into SQL queries without proper sanitization, while the second vector operates through the prod parameter which similarly lacks adequate validation measures. Both parameters are processed within the index.php script and passed directly to database queries without appropriate escaping or parameterization techniques, allowing attackers to manipulate the intended query structure and execute unauthorized database commands. This represents a classic case of improper input validation that aligns with CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is incorporated into SQL commands without proper sanitization.
The operational impact of this vulnerability extends far beyond simple data theft, as successful exploitation enables attackers to perform a wide range of malicious activities including unauthorized data access, modification, or deletion. Attackers can leverage these vulnerabilities to escalate privileges, extract sensitive information such as user credentials, customer data, or administrative access details, and potentially gain complete control over the affected web application and its underlying database. The remote nature of the attack means that exploitation can occur from any location without requiring physical access to the system, making it particularly dangerous for web applications that handle sensitive data or provide administrative functionality. This vulnerability directly maps to several ATT&CK techniques including T1190 for exploit public-facing application and T1071.004 for application layer protocol, as it exploits weaknesses in web application protocols and interfaces.
Organizations utilizing FreeWebshop 2.2.1 or earlier versions face significant security risks due to this vulnerability, as it provides attackers with direct pathways to compromise the entire web application infrastructure. The vulnerability's persistence across multiple parameters within a single script demonstrates a systemic flaw in the application's security architecture that requires comprehensive remediation. Mitigation strategies must include immediate implementation of proper input validation and sanitization measures, adoption of parameterized queries or prepared statements, and thorough code review processes to identify similar vulnerabilities throughout the application. Additionally, organizations should implement web application firewalls, conduct regular security assessments, and ensure timely patch management to prevent exploitation of known vulnerabilities. The vulnerability also highlights the importance of following secure coding practices and adhering to industry standards such as OWASP Top Ten and NIST cybersecurity frameworks to prevent similar issues in future development cycles.
