The vulnerability identified as CVE-2011-5039 represents a critical security flaw in the Infoproject Biznis Heroj web application that exposes multiple pathways for remote SQL injection attacks. This vulnerability affects several key components of the application's authentication and data retrieval mechanisms, creating significant risks for unauthorized access and data manipulation. The flaw stems from insufficient input validation and sanitization within the application's PHP scripts, particularly in the login functionality and various data listing modules.
The technical implementation of this vulnerability allows attackers to inject malicious SQL commands through four distinct parameter injection points within the web application. The primary attack vectors include the username and password parameters in the login.php script, which directly impacts the authentication system and could enable unauthorized access to user accounts. Additionally, the filter parameter in widget.dokumenti_lista.php and the fin_nalog_id parameter in nalozi_naslov.php provide alternative pathways for attackers to manipulate database queries and potentially extract sensitive information from the backend database. These injection points demonstrate poor input handling practices where user-supplied data is directly incorporated into SQL queries without proper sanitization or parameterization.
The operational impact of CVE-2011-5039 extends beyond simple data theft, as successful exploitation could lead to complete database compromise, user account takeover, and potential system infiltration. Attackers could leverage these vulnerabilities to extract confidential information including user credentials, personal data, and business-sensitive documents stored within the application's database. The vulnerability's classification aligns with CWE-89 which specifically addresses SQL injection flaws, and maps to ATT&CK technique T1190 for exploitation of vulnerabilities in web applications. The attack surface is particularly concerning given that the vulnerabilities affect core authentication and data retrieval functions, potentially allowing attackers to escalate privileges and maintain persistent access to the compromised system.
Organizations utilizing Infoproject Biznis Heroj must implement immediate mitigations to address this vulnerability, including input validation and parameterized query implementation across all affected script parameters. The recommended approach involves sanitizing all user inputs through proper escaping mechanisms and implementing prepared statements to prevent SQL injection exploitation. Additionally, access controls should be strengthened and input validation should be enforced at multiple layers within the application architecture. Regular security assessments and code reviews are essential to identify similar vulnerabilities in other application components, as this vulnerability demonstrates the importance of secure coding practices. The remediation efforts should align with industry standards such as OWASP Top Ten and NIST cybersecurity guidelines, particularly focusing on input validation and secure database interaction practices to prevent similar vulnerabilities from emerging in future application versions.
