CVE-2023-45345

Comprehensive Technical Analysis of CVE-2023-45345

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-45345 CISA Vulnerability Name: CVE-2023-45345 Description: Online Food Ordering System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The '*_deleted' 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 Severity: Critical

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the unauthenticated nature of the SQL injection, which allows attackers to exploit the vulnerability without needing any credentials. The lack of input validation and filtering exacerbates the risk, making it a high-priority issue for immediate remediation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: Attackers can inject malicious SQL code into the '*_deleted' parameter of the routers/user-router.php resource without needing to authenticate.
• Data Exfiltration: Attackers can extract sensitive information from the database, including user credentials, personal information, and financial data.
• Data Manipulation: Attackers can modify or delete database entries, leading to data integrity issues.
• Privilege Escalation: By exploiting SQL injection, attackers can gain elevated privileges within the database, potentially leading to full system compromise.

Exploitation Methods:

• Manual SQL Injection: Attackers can manually craft SQL queries to exploit the vulnerability.
• 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 Software:

• Online Food Ordering System v1.0

Affected Components:

• routers/user-router.php resource
• Any other components that handle the '*_deleted' parameter without proper validation

Software Versions:

• All versions up to and including v1.0 are affected.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for the '*_deleted' parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to interact with the database, ensuring that user inputs are treated as data rather than executable code.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.

Long-Term Strategies:

• Code Review: Conduct thorough code reviews to identify and fix similar vulnerabilities.
• Security Training: Provide training for developers on secure coding practices and common vulnerabilities.
• Regular Audits: Perform regular security audits and penetration testing to identify and mitigate potential vulnerabilities.

5. Impact on Cybersecurity Landscape

The presence of unauthenticated SQL injection vulnerabilities in widely used systems like Online Food Ordering System v1.0 highlights the ongoing challenge of securing web applications. This vulnerability underscores the importance of robust input validation, secure coding practices, and regular security audits. The high CVSS score indicates the potential for significant damage, including data breaches, financial loss, and reputational harm. Organizations must prioritize security in their software development lifecycle to mitigate such risks.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameter: '*_deleted' in routers/user-router.php
• Exploit Method: Injecting malicious SQL code into the '*_deleted' parameter without authentication.
• Example Exploit:

  ' OR '1'='1
  

  This payload can be used to bypass authentication or extract data.

Detection Methods:

• Static Analysis: Use static analysis tools to identify unvalidated user inputs and SQL queries.
• Dynamic Analysis: Employ dynamic analysis tools to simulate attacks and detect vulnerabilities in real-time.
• Log Monitoring: Monitor application logs for unusual SQL queries or error messages indicative of SQL injection attempts.

Mitigation Techniques:

• Input Validation: Ensure all user inputs are validated and sanitized.
• Parameterized Queries: Replace dynamic SQL queries with parameterized queries.
• Least Privilege: Implement the principle of least privilege for database access, limiting the permissions of the database user.
