CVE-2023-45341

Comprehensive Technical Analysis of CVE-2023-45341

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-45341 Description: Online Food Ordering System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The *_price parameter of the routers/menu-router.php resource does not validate the characters received and they are sent unfiltered to the database.

CVSS Score: 9.8 Severity: Critical

The CVSS score of 9.8 indicates a highly severe vulnerability. This score reflects the potential for significant impact on the confidentiality, integrity, and availability of the affected system. The unauthenticated nature of the vulnerability means that any attacker can exploit it without needing to authenticate, making it particularly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: An attacker can inject malicious SQL code into the *_price parameter without needing to authenticate.
• Data Exfiltration: By crafting specific SQL queries, an attacker can extract sensitive information from the database, such as user credentials, payment information, and order details.
• Data Manipulation: The attacker can modify database entries, leading to unauthorized changes in the system.
• Denial of Service (DoS): An attacker can execute SQL commands that disrupt the normal operation of the database, leading to service unavailability.

Exploitation Methods:

• Manual SQL Injection: An attacker can manually craft SQL queries and input them into the *_price parameter to test for vulnerabilities.
• Automated Tools: Use of automated SQL injection tools like SQLmap to identify and exploit the vulnerability.
• Scripting: Writing custom scripts to automate the injection process and extract data.

3. Affected Systems and Software Versions

Affected System: Online Food Ordering System v1.0 Affected Resource: routers/menu-router.php

All instances of the Online Food Ordering System v1.0 that use the routers/menu-router.php resource are vulnerable. This includes any deployment of the system, whether on-premises or cloud-based.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor to address the vulnerability.
• Input Validation: Implement robust input validation and sanitization for all user inputs, especially for the *_price parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to interact with the database, ensuring that user inputs are not directly included in SQL queries.
• Web Application Firewall (WAF): Deploy a WAF to monitor and block malicious SQL injection attempts.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.
• Code Review: Implement a rigorous code review process to ensure that all inputs are properly validated and sanitized.
• Security Training: Provide security training for developers to educate them on secure coding practices and common vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2023-45341 highlights the ongoing challenge of SQL injection vulnerabilities in web applications. Despite being a well-known issue, SQL injection remains a prevalent threat due to inadequate input validation and sanitization practices. This vulnerability underscores the importance of adhering to secure coding standards and regularly updating and patching software.

The high CVSS score and the unauthenticated nature of the vulnerability make it a significant concern for organizations using the affected software. It serves as a reminder that even seemingly minor parameters can be exploited to cause significant damage if not properly secured.

6. Technical Details for Security Professionals

Vulnerability Details:

• Parameter: *_price
• Resource: routers/menu-router.php
• Issue: Lack of input validation and sanitization leading to unfiltered SQL queries being sent to the database.

Exploitation Example: An attacker could input a malicious SQL query into the *_price parameter, such as:

100 OR 1=1; --

This would bypass any authentication checks and potentially allow the attacker to extract sensitive data from the database.

Mitigation Example: Using parameterized queries in PHP:

$stmt = $pdo->prepare("SELECT * FROM menu WHERE price = :price");
$stmt->bindParam(':price', $price);
$stmt->execute();

This ensures that the price parameter is treated as a bound variable, preventing SQL injection.
