CVE-2023-45344

Comprehensive Technical Analysis of CVE-2023-45344

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-45344 Description: Online Food Ordering System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The *_balance parameter of the routers/user-router.php resource does not validate the characters received and they are sent unfiltered to the database.

CVSS Score: 9.8 Status: Modified

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthenticated attackers to exploit the vulnerability, leading to significant impacts such as data breaches, unauthorized access, and potential system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: An attacker can inject malicious SQL queries into the *_balance parameter without needing to authenticate.
• Parameter Manipulation: The lack of input validation allows attackers to manipulate the *_balance parameter to execute arbitrary SQL commands.

Exploitation Methods:

• Direct SQL Injection: Attackers can craft SQL queries to extract sensitive data, modify database entries, or delete records.
• Union-Based SQL Injection: By using UNION SELECT statements, attackers can retrieve data from other tables.
• Error-Based SQL Injection: Exploiting error messages to gather information about the database structure.

3. Affected Systems and Software Versions

Affected Systems:

• Online Food Ordering System v1.0

Software Versions:

• Specifically, the vulnerability is present in version 1.0 of the Online Food Ordering System.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Input Validation: Implement strict input validation and sanitization for the *_balance parameter to ensure only expected characters and formats are accepted.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks.
• Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.

Long-Term Mitigation:

• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities in other parts of the application.
• Security Training: Provide security training for developers to understand and mitigate SQL injection risks.
• Regular Updates: Ensure the application is regularly updated and patched to address newly discovered vulnerabilities.

5. Impact on Cybersecurity Landscape

Impact:

• Data Breaches: Unauthenticated SQL injection vulnerabilities can lead to significant data breaches, compromising user information and financial data.
• Reputation Damage: Organizations using the affected system may suffer reputational damage due to data breaches and loss of customer trust.
• Compliance Issues: Failure to address such vulnerabilities can result in non-compliance with data protection regulations, leading to legal consequences.

6. Technical Details for Security Professionals

Technical Analysis:

• Vulnerable Resource: routers/user-router.php
• Vulnerable Parameter: *_balance
• Exploit Method: The parameter does not validate input, allowing attackers to inject SQL commands directly into the database query.

Example Exploit:

SELECT * FROM users WHERE balance = '100' OR '1'='1'; --

This query would return all records from the users table, bypassing the intended filter.

Mitigation Code Example:

// Using prepared statements in PHP
$stmt = $pdo->prepare("SELECT * FROM users WHERE balance = :balance");
$stmt->bindParam(':balance', $balance);
$stmt->execute();
