Summary
by MITRE • 11/08/2023
Online Matrimonial Project v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The 'pass' parameter in the 'register()' function of the functions.php resource does not validate the characters received and they are sent unfiltered to the database.

The Online Matrimonial Project v1.0 presents a critical security vulnerability through multiple unauthenticated SQL injection flaws that directly impact its user registration functionality. This vulnerability specifically targets the 'pass' parameter within the 'register()' function located in the functions.php resource file, creating a pathway for malicious actors to manipulate database queries without proper authentication. The flaw stems from inadequate input validation mechanisms that fail to sanitize or filter user-provided data before executing database operations, allowing attackers to inject malicious SQL commands through the password parameter during user registration processes.
The technical nature of this vulnerability aligns with CWE-89 which describes improper neutralization of special elements used in SQL commands, and represents a classic SQL injection attack vector that operates at the application level. Attackers can exploit this weakness by crafting malicious input strings that bypass normal validation checks, enabling them to execute arbitrary SQL commands against the backend database. The unfiltered nature of the 'pass' parameter means that any special SQL characters or commands entered by users are directly passed to database engines without proper escaping or sanitization, potentially allowing full database access, data manipulation, or even database destruction.
Operationally, this vulnerability poses severe risks to the platform's security posture and user data integrity. An unauthenticated attacker can exploit this flaw to extract sensitive information from the database including user credentials, personal details, and potentially system configuration data. The impact extends beyond simple data theft as attackers could modify user accounts, inject malicious code, or escalate privileges within the application. The vulnerability affects the core registration functionality, meaning any user attempting to create an account could be exploited, and the lack of authentication requirements makes it particularly dangerous as attackers need no valid credentials to initiate exploitation attempts. This weakness directly violates security principles outlined in the OWASP Top Ten 2021, specifically addressing injection flaws and inadequate input validation.
Mitigation strategies should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. The most effective approach involves using prepared statements with parameterized queries to ensure user input cannot alter the intended SQL command structure. Additionally, implementing proper input sanitization, character set validation, and limiting database user privileges can significantly reduce the impact of potential exploitation attempts. Regular security code reviews and automated vulnerability scanning should be implemented to identify similar weaknesses throughout the application. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for suspicious database access patterns that might indicate exploitation attempts. The vulnerability demonstrates the critical importance of following secure coding practices and adhering to defense-in-depth strategies as outlined in the MITRE ATT&CK framework for application-level attacks.
