CVE-2009-1813 in Submitterscript
Summary
by MITRE
Multiple SQL injection vulnerabilities in admin/index.php in Submitter Script 2 allow remote attackers to execute arbitrary SQL commands via (1) the uNev parameter (aka the username field) or (2) the uJelszo parameter (aka the Password field).

The vulnerability identified as CVE-2009-1813 represents a critical SQL injection flaw within the Submitter Script 2 administrative interface, specifically in the admin/index.php file. This vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into database queries. The flaw affects two distinct parameters within the authentication mechanism, namely the uNev parameter which corresponds to the username field and the uJelszo parameter which maps to the password field, creating a pathway for malicious actors to manipulate the underlying database operations through crafted input sequences.
The technical exploitation of this vulnerability occurs through parameter manipulation techniques that leverage the absence of proper input sanitization. When attackers submit malicious payloads through either the username or password fields, the application fails to properly escape special characters or implement parameterized queries, allowing the injected SQL code to execute within the database context. This vulnerability directly maps to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields that are subsequently processed by database servers, enabling unauthorized data access, modification, or deletion operations. The attack vector operates through the standard HTTP request mechanism where malicious input is transmitted to the vulnerable application endpoint.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can enable attackers to gain unauthorized administrative access to the application, extract sensitive user credentials, modify or delete database records, and potentially escalate privileges within the system. Given that this vulnerability affects the administrative interface, attackers could manipulate the entire application functionality, compromise user accounts, and establish persistent access points within the target environment. The vulnerability's remote nature means that attackers do not require physical access to the system, making it particularly dangerous for web applications that are publicly accessible and lack proper network segmentation controls.
Mitigation strategies for this vulnerability should prioritize immediate implementation of parameterized queries or prepared statements to ensure that user input is properly separated from database commands. The application should implement comprehensive input validation and sanitization routines that filter or escape special characters commonly used in SQL injection attacks, including single quotes, semicolons, and comment markers. Additionally, access controls should be strengthened through proper authentication mechanisms, including account lockout procedures and secure password storage practices. Network-level protections such as web application firewalls and intrusion detection systems can provide additional layers of defense, while regular security audits and code reviews should be conducted to identify similar vulnerabilities within the application codebase. The remediation efforts should align with industry standards such as those outlined in the OWASP Top Ten project and NIST cybersecurity guidelines for preventing injection vulnerabilities in web applications.
