Critical SQL Injection Vulnerabilities in Blood Bank & Restaurant Management Systems

 Critical SQL Injection Vulnerabilities in Blood Bank & Restaurant Management Systems

About the Critical Vulnerabilities disclosed on April 6, 2025:

1. CVE-2025-3308: SQL Injection in Blood Bank Management System

Overview 
CVE-2025-3308 is a critical SQL injection vulnerability in the Blood Bank Management System version 1.0. The vulnerability resides in the /viewrequest.php file, where improper handling of the ID parameter allows attackers to inject arbitrary SQL commands into the database. This flaw can be exploited remotely, and the exploit has been disclosed publicly.

Impact
Exploitation of this vulnerability could allow attackers to:

• Execute arbitrary SQL commands.

• Access, modify, or delete sensitive database information.

• Compromise the integrity and confidentiality of the system.

Scenario
An attacker crafts a malicious URL like http://example.com/viewrequest.php?ID=' OR '1'='1 to bypass authentication or retrieve sensitive data from the database.

Mitigation Steps

• Sanitize and validate user inputs for the ID parameter.

• Use parameterized queries or prepared statements.

• Regularly audit code for vulnerabilities.

2. CVE-2025-3333: SQL Injection in Online Restaurant Management System

Overview
This vulnerability affects the /admin/menu_update.php file in Online Restaurant Management System version 1.0. Improper neutralization of special characters in the menu parameter allows attackers to perform SQL injection attacks remotely. The CVSS score for this vulnerability is 7.3 (High).

Impact
Attackers can:

• Inject malicious SQL commands.

• Gain unauthorized access to sensitive data.

• Alter or delete critical information.

Scenario
An attacker submits a POST request with malicious payloads such as:

text
POST /admin/menu_update.php HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded

menu='; DROP TABLE orders; --

Mitigation Steps

• Validate and sanitize all user inputs.

• Implement prepared statements for database queries.

• Restrict database permissions to minimize impact.

3. CVE-2025-3332: SQL Injection in /admin/menu_save.php

Overview
This critical vulnerability exists in the /admin/menu_save.php file of Online Restaurant Management System version 1.0. The improper handling of the menu parameter allows attackers to execute remote SQL injection attacks.

Impact
Successful exploitation can lead to:

• Unauthorized access to database records.

• Data manipulation or deletion.

• Potential compromise of application functionality.

Scenario
An attacker sends a crafted request like:

text
POST /admin/menu_save.php HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded

menu='); SELECT * FROM users; --

Mitigation Steps

• Input validation and sanitization for all parameters.

• Use prepared statements and parameterized queries.

• Monitor logs for unusual activity related to database queries.

4. CVE-2025-3331: SQL Injection in /payment_save.php

Overview
CVE-2025-3331 is another critical SQL injection vulnerability affecting Online Restaurant Management System version 1.0. The flaw lies in the /payment_save.php file, where manipulation of the mode argument can lead to malicious SQL execution.

Impact
This vulnerability can allow attackers to:

• Inject and execute arbitrary SQL commands.

• Access or modify sensitive payment information.

• Compromise database integrity.

Scenario
An attacker sends a GET request like:

text
http://example.com/payment_save.php?mode=' UNION SELECT username, password FROM users; --

Mitigation Steps

• Sanitize input parameters such as mode.

• Use database security best practices like least privilege access.

• Regularly update software with patches.

5. CVE-2025-3330: SQL Injection in /reservation_save.php

Overview
This critical vulnerability impacts Online Restaurant Management System version 1.0, specifically in the /reservation_save.php file. The issue arises from improper handling of the first parameter, which could allow remote attackers to execute arbitrary SQL commands.

Impact
Attackers exploiting this flaw may:

• Compromise reservation data integrity.

• Retrieve sensitive customer information.

• Potentially escalate privileges within the system.

Scenario
A crafted request might look like:

text
POST /reservation_save.php HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded

first=' OR '1'='1'; --

Mitigation Steps

• Validate and sanitize inputs for parameters like first.

• Employ prepared statements and stored procedures.

• Conduct regular penetration testing on web applications.

General Recommendations for All Vulnerabilities

To mitigate these vulnerabilities effectively:

1. Sanitize Inputs: Always validate and sanitize user inputs before processing them.

2. Use Parameterized Queries: Replace dynamic SQL queries with parameterized ones to prevent injection attacks.

3. Apply Patches: Update affected software versions as soon as patches are available.

4. Database Permissions: Implement least privilege principles for database accounts.

5. Monitoring and Logging: Monitor database access logs for suspicious activities and enforce logging mechanisms.

6. Web Application Firewalls (WAFs): Deploy WAFs to detect and block malicious requests proactively.

By addressing these vulnerabilities promptly, organizations can significantly reduce their exposure to potential exploits and protect their systems from unauthorized access or data breaches.
