CVE-2024-3003 Overview
A critical SQL Injection vulnerability has been identified in Anisha Online Book System version 1.0. This vulnerability exists in the /cart.php file where the quantity and remove parameters are improperly sanitized, allowing attackers to inject malicious SQL queries. The attack can be launched remotely without authentication, potentially leading to full database compromise, unauthorized data access, and data manipulation.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection flaw to extract sensitive data, modify database contents, or potentially gain full control over the underlying database server.
Affected Products
- Anisha Online Book System 1.0
- Applications using the vulnerable /cart.php endpoint
- Deployments with unsanitized user input handling in cart functionality

Technical Details for CVE-2024-3003
Vulnerability Analysis
This SQL Injection vulnerability stems from improper input validation in the shopping cart functionality of the Online Book System. The application fails to properly sanitize user-supplied input in the quantity and remove parameters before incorporating them into SQL queries. This allows an attacker to inject arbitrary SQL commands that will be executed by the database engine.
The vulnerability is particularly severe because it requires no authentication to exploit. An attacker can craft malicious HTTP requests targeting the /cart.php endpoint and manipulate the vulnerable parameters to execute unauthorized database operations. Successful exploitation could result in complete compromise of confidentiality, integrity, and availability of the database and its contents.
Root Cause
The root cause of this vulnerability is the lack of proper input sanitization and parameterized queries in the /cart.php file. The application directly concatenates user-supplied values from the quantity and remove parameters into SQL statements without proper escaping or using prepared statements. This fundamental coding flaw allows attackers to break out of the intended SQL query context and inject their own malicious SQL commands.
Attack Vector
The attack is network-based and can be executed remotely by any unauthenticated user. An attacker would craft a malicious HTTP request to the /cart.php endpoint with specially crafted values in the quantity or remove parameters. These payloads would include SQL syntax designed to manipulate the query logic, extract data through UNION-based injection, or execute blind SQL injection techniques.
The vulnerability can be exploited through standard web requests, making it trivially accessible to attackers with basic SQL injection knowledge. Detailed technical information about this vulnerability is available in the GitHub PoC Repository.
Detection Methods for CVE-2024-3003
Indicators of Compromise
- Unusual or malformed HTTP requests to /cart.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or semicolons
- Database error messages appearing in web application logs or responses
- Unexpected database queries or operations in database audit logs
- Anomalous data exfiltration patterns or database response times
Detection Strategies
- Deploy Web Application Firewalls (WAF) with SQL injection detection rules targeting the /cart.php endpoint
- Implement application-level logging to capture all requests to cart functionality with parameter values
- Enable database query logging and monitor for suspicious query patterns or syntax anomalies
- Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Monitor web server access logs for requests to /cart.php containing encoded or obfuscated SQL injection payloads
- Set up alerts for database errors or exceptions that may indicate injection attempts
- Track unusual database activity such as bulk data reads or schema enumeration queries
- Implement rate limiting on the cart endpoint to slow potential automated exploitation attempts
How to Mitigate CVE-2024-3003
Immediate Actions Required
- Immediately restrict access to the /cart.php endpoint if possible until remediation is complete
- Implement input validation and sanitization for all user-supplied parameters, especially quantity and remove
- Deploy WAF rules to block common SQL injection patterns targeting the vulnerable endpoint
- Review database permissions to ensure the application uses least-privilege database accounts
Patch Information
No official vendor patch is currently available for this vulnerability. Organizations using the affected Online Book System should implement the recommended workarounds and monitor for updates from the vendor. Additional information can be found in the VulDB advisory.
Workarounds
- Refactor the vulnerable code to use parameterized queries or prepared statements instead of string concatenation
- Implement strict input validation that only allows expected data types (e.g., integers for quantity values)
- Deploy a Web Application Firewall with SQL injection protection enabled for the affected application
- Consider disabling or restricting access to the cart functionality until proper fixes can be implemented
- Apply database-level security controls to limit the impact of potential SQL injection attacks
The recommended approach is to update the vulnerable PHP code to use prepared statements. Instead of directly concatenating user input into SQL queries, use parameterized queries with bound variables to ensure user input is treated as data rather than executable SQL code.
