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

The Online Food Ordering System v1.0 presents a critical security vulnerability through multiple unauthenticated SQL injection flaws that compromise the underlying database integrity and confidentiality. This vulnerability specifically targets the routers/add-users.php endpoint where the 'role' parameter receives user input without proper sanitization or validation mechanisms. The absence of input filtering creates an exploitable condition where malicious actors can inject arbitrary SQL commands directly into the database query execution pipeline. This weakness allows attackers to manipulate the database structure, extract sensitive information, modify user credentials, or even escalate privileges within the system. The vulnerability exists at the application layer and represents a fundamental failure in input validation practices, making it particularly dangerous as it requires no authentication to exploit. The impact extends beyond simple data theft to potentially enable complete system compromise and unauthorized access to user accounts and personal information.
The technical exploitation of this vulnerability follows standard SQL injection attack patterns where the 'role' parameter becomes the attack vector for injecting malicious SQL payloads. Attackers can construct specially crafted inputs that bypass normal validation checks and execute unintended database operations. The lack of proper parameterized queries or input sanitization means that user-supplied data flows directly into database commands without proper escaping or encoding. This vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in software applications and represents a classic example of insufficient input validation. The attack surface is further expanded by the fact that this vulnerability is unauthenticated, meaning any external party can exploit it without requiring valid credentials or prior access to the system. The database operations performed through this interface likely involve user account creation and role assignment, making it a prime target for privilege escalation attacks.
The operational impact of this vulnerability creates significant risk for both system administrators and end users of the food ordering platform. Unauthorized individuals can gain access to sensitive user information including personal details, order histories, and potentially payment information stored within the database. The ability to inject SQL commands allows for data exfiltration, data modification, and in severe cases, complete database compromise. Attackers may also use this vulnerability to escalate privileges and gain administrative access to the system, potentially leading to full system control. The vulnerability affects the integrity and availability of the service, as malicious actors could delete or corrupt database entries, disrupt service operations, or create backdoor access points for future exploitation. Organizations relying on this system face potential regulatory compliance violations, reputational damage, and financial losses due to data breaches and service disruption.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements within the application architecture. The primary fix involves implementing proper input validation and sanitization for all user-supplied parameters, particularly the 'role' parameter in the routers/add-users.php endpoint. This includes using parameterized queries or prepared statements to ensure that user input cannot be interpreted as SQL commands. The system should implement strict character validation and length restrictions for all input fields, rejecting any input containing potentially dangerous SQL metacharacters. Additionally, the application should employ proper error handling that does not reveal database structure information to users. Network-level protections such as web application firewalls and intrusion detection systems can provide additional layers of defense. Regular security code reviews and penetration testing should be conducted to identify similar vulnerabilities throughout the application codebase. Implementation of the principle of least privilege for database connections and regular security updates for the application framework will further reduce the attack surface and improve overall system resilience against similar threats.
