CVE-2024-9814 Overview
A SQL injection vulnerability has been identified in Codezips Pharmacy Management System version 1.0. The vulnerability exists in the product/update.php file where the id parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to inject malicious SQL commands and potentially compromise the database backend of the pharmacy management system.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive pharmacy data, modify database records, or potentially gain unauthorized access to the underlying system without authentication.

Technical Details for CVE-2024-9814
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) affects the product update functionality within the Codezips Pharmacy Management System. The vulnerable endpoint at product/update.php fails to properly validate or sanitize the id parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are executed by the database server.
The attack can be launched remotely over the network without requiring any authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild. Pharmacy management systems typically contain sensitive healthcare data, prescription records, and patient information, making this vulnerability particularly concerning from a data privacy perspective.
Root Cause
The root cause of this vulnerability is improper input validation (CWE-89: Improper Neutralization of Special Elements used in an SQL Command). The application directly incorporates user-supplied input from the id parameter into SQL queries without proper sanitization, parameterization, or prepared statement usage. This classic SQL injection pattern allows attackers to break out of the intended query structure and execute arbitrary database commands.
Attack Vector
The vulnerability is exploitable via network-based attacks targeting the product/update.php endpoint. An attacker can manipulate the id parameter to inject SQL syntax that alters the query's logic. Successful exploitation could allow the attacker to:
- Extract sensitive data from the pharmacy database including patient records and prescription information
- Modify or delete database records, potentially corrupting pharmacy inventory data
- Bypass authentication mechanisms if the same database handles user credentials
- Potentially execute system commands if database permissions allow
The attack does not require any prior authentication or special privileges, making it accessible to unauthenticated remote attackers. Technical details and proof-of-concept information are available in the GitHub Issue Discussion.
Detection Methods for CVE-2024-9814
Indicators of Compromise
- Unusual SQL error messages in application logs from the product/update.php endpoint
- HTTP requests to product/update.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords in the id parameter
- Database audit logs showing unexpected queries or data extraction attempts
- Anomalous database query patterns originating from the web application
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the pharmacy management system
- Monitor HTTP access logs for requests containing SQL injection payloads targeting product/update.php
- Enable database query logging and alert on suspicious query patterns or syntax errors
- Deploy intrusion detection systems (IDS) with signatures for SQL injection attacks
Monitoring Recommendations
- Enable verbose logging on the web server and database to capture potential exploitation attempts
- Set up real-time alerting for database errors or unexpected query failures
- Monitor for unusual data access patterns or bulk data extraction from pharmacy-related tables
- Implement file integrity monitoring on the Pharmacy Management System installation
How to Mitigate CVE-2024-9814
Immediate Actions Required
- Restrict network access to the Codezips Pharmacy Management System to trusted IP addresses only
- Implement a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
- Review database permissions and ensure the application uses least-privilege database accounts
- Consider taking the affected system offline until a patch is available or mitigations are in place
Patch Information
No official patch information is currently available from the vendor. Organizations using Codezips Pharmacy Management System 1.0 should monitor the VulDB entry for updates on remediation guidance. In the absence of a vendor patch, implementing the workarounds below is strongly recommended.
Workarounds
- Implement input validation on the id parameter to accept only numeric values
- Deploy a WAF rule to block requests containing SQL injection patterns in the id parameter
- Use database stored procedures with parameterized queries if modifying source code is possible
- Restrict database user permissions to minimize impact of potential exploitation
- Implement network segmentation to isolate the pharmacy management system from critical infrastructure
# Example WAF rule for ModSecurity to block SQL injection on the id parameter
SecRule ARGS:id "(?i)(union|select|insert|update|delete|drop|--|;|'|\")" \
"id:100001,phase:2,deny,status:403,msg:'SQL Injection attempt blocked on id parameter'"
