Summary
by MITRE • 11/02/2023
Online Food Ordering System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The 'username' parameter of the routers/router.php resource does not validate the characters received and they are sent unfiltered to the database.

The vulnerability identified as CVE-2023-45337 affects the Online Food Ordering System version 1.0, presenting a critical security risk through multiple unauthenticated SQL injection flaws. This vulnerability specifically targets the username parameter within the routers/router.php resource, where input validation mechanisms have been completely bypassed. The absence of proper sanitization allows malicious actors to inject arbitrary SQL commands directly into the database query execution process without requiring any authentication credentials.
The technical flaw manifests as a failure in input validation and sanitization practices, which constitutes a direct violation of secure coding principles and falls under the Common Weakness Enumeration category CWE-89 SQL Injection. The vulnerability exists because the application accepts user-supplied data from the username parameter and directly incorporates it into SQL queries without proper escaping or parameterization. This design flaw enables attackers to manipulate the underlying database structure and potentially execute unauthorized commands. The vulnerability is classified as unauthenticated, meaning that any user with access to the system can exploit it without requiring valid credentials, significantly expanding the attack surface.
The operational impact of this vulnerability is severe and multifaceted. Successful exploitation could allow attackers to extract sensitive user data including usernames, passwords, and personal information stored in the database. Additionally, attackers might gain the ability to modify or delete database records, potentially compromising the integrity of the entire food ordering system. The vulnerability could also facilitate further attacks within the network infrastructure if the database server has elevated privileges or if the application uses the same credentials for multiple systems. This type of vulnerability directly impacts the confidentiality, integrity, and availability of the system as outlined in the CIA triad of information security.
Mitigation strategies for this vulnerability should focus on implementing robust input validation and sanitization mechanisms. The primary recommendation involves implementing proper parameterized queries or prepared statements to ensure that user input cannot be interpreted as SQL commands. Additionally, the application should enforce strict input validation on the username parameter to reject potentially malicious characters and sequences. Network-level protections such as web application firewalls should be deployed to detect and block suspicious SQL injection patterns. Regular security testing including automated vulnerability scanning and manual penetration testing should be conducted to identify similar issues throughout the codebase. The system should also implement proper access controls and authentication mechanisms to limit potential damage from any successful exploitation attempts. Organizations should follow the ATT&CK framework guidance for defensive measures against SQL injection attacks, particularly focusing on techniques such as input validation and query parameterization to prevent the exploitation of such vulnerabilities.
