The vulnerability identified as CVE-2013-10018 represents a critical sql injection flaw in the fanzila WebFinance 0.5 web application. This security weakness resides within the htdocs/prospection/save_contact.php file, which processes contact information submissions from users. The vulnerability stems from inadequate input validation and sanitization of user-supplied data, specifically affecting parameters including nom (name), prenom (first name), email, tel (telephone), mobile, client, fonction (position), and note (description fields). Attackers can exploit this flaw by manipulating these input parameters to inject malicious sql commands into the backend database system, potentially gaining unauthorized access to sensitive information or executing arbitrary database operations.
The technical exploitation of this vulnerability follows established sql injection attack patterns where user input is directly concatenated into sql queries without proper sanitization or parameterization. When an attacker submits malicious data through any of the vulnerable parameters, the application fails to properly escape or validate special sql characters and keywords, allowing attackers to manipulate the intended sql query execution flow. This type of vulnerability falls under the CWE-89 classification for sql injection, which is categorized as a critical weakness in software security. The attack vector demonstrates the classic lack of input validation and the absence of proper database query parameterization techniques that are fundamental to preventing sql injection attacks.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to extract confidential data, modify or delete database records, and in some cases gain full administrative control over the database system. Given that the application appears to be a financial management tool, the compromised data could include sensitive financial information, user credentials, and business-related details. The vulnerability affects the core functionality of contact management within the web finance system, making it a prime target for attackers seeking to compromise the entire application's data integrity and availability. The critical severity rating indicates that this vulnerability can be exploited without requiring specialized skills or access to the system, making it particularly dangerous in real-world deployment scenarios.
Mitigation strategies for this vulnerability must include immediate application of the provided patch with the identifier 165dfcaa0520ee0179b7c1282efb84f5a03df114. Organizations should implement proper input validation and sanitization measures, ensuring that all user-supplied data is properly escaped or parameterized before being processed by the database. The recommended approach involves adopting prepared statements or parameterized queries to eliminate the possibility of sql injection attacks. Additionally, implementing proper access controls, database query monitoring, and regular security audits can help detect and prevent exploitation attempts. This vulnerability aligns with several ATT&CK techniques including T1190 for exploit public-facing application and T1071.004 for application layer protocol. Organizations should also consider implementing web application firewalls and input validation rules to prevent malicious payloads from reaching the vulnerable application components. The patch should be applied immediately, and comprehensive testing should be performed to ensure that the fix does not introduce regressions in the application's functionality while maintaining the security of the contact management system.
