CVE-2024-9813: Codezips Pharmacy Management SQL Injection

CVE-2024-9813 Overview

A critical SQL injection vulnerability has been identified in Codezips Pharmacy Management System version 1.0. This security flaw exists in the product/register.php file, where insufficient input validation of the category parameter allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, and information disclosure.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive pharmacy and patient data stored in the backend database without requiring authentication.

Affected Products

Technical Details for CVE-2024-9813

Vulnerability Analysis

This SQL injection vulnerability arises from improper handling of user-supplied input in the category parameter within the product/register.php endpoint. When a user submits data through this parameter, the application fails to properly sanitize or parameterize the input before incorporating it into SQL queries. This allows an attacker to inject arbitrary SQL commands that are then executed by the underlying database engine.

The vulnerability is accessible over the network and does not require user interaction or prior authentication to exploit. Once exploited, attackers can potentially read sensitive data from the database, modify existing records, delete data, or in some configurations, execute administrative operations on the database server itself.

Healthcare management systems like pharmacy applications typically store highly sensitive information including patient records, prescription histories, inventory data, and financial transactions. Compromise of such systems can result in regulatory violations (such as HIPAA in the United States), financial losses, and significant reputational damage.

Root Cause

The root cause of CVE-2024-9813 is the failure to implement proper input validation and parameterized queries (prepared statements) in the product/register.php file. The application directly concatenates user input from the category parameter into SQL query strings without sanitization, allowing specially crafted input to alter the intended SQL command structure.

Attack Vector

The attack is initiated remotely via network access to the vulnerable web application. An attacker can craft malicious HTTP requests targeting the product/register.php endpoint, manipulating the category parameter with SQL injection payloads. The vulnerability requires no authentication or special privileges, making it accessible to any network-level attacker who can reach the application.

The attacker constructs a malicious value for the category parameter that includes SQL syntax designed to break out of the intended query context. This can include UNION-based injections to retrieve data from other tables, boolean-based blind injections to enumerate database contents, or stacked queries to perform additional database operations. For detailed technical analysis and proof-of-concept information, refer to the GitHub CVE Issue Discussion and the VulDB entry #279965.

Detection Methods for CVE-2024-9813

Indicators of Compromise

• Anomalous HTTP requests to product/register.php containing SQL keywords (UNION, SELECT, INSERT, DROP, etc.) in the category parameter
• Database error messages in application logs indicating malformed SQL queries
• Unexpected database query patterns or execution times in database logs
• Evidence of data exfiltration or unauthorized data access in audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP request parameters
• Enable detailed logging for the product/register.php endpoint and monitor for suspicious parameter values
• Configure database monitoring to alert on unusual query patterns, including queries containing UNION statements or comments
• Deploy SentinelOne Singularity XDR to detect post-exploitation activities and lateral movement attempts following database compromise

Monitoring Recommendations

• Monitor web server access logs for repeated requests to product/register.php with varying category parameter values
• Set up alerts for database errors that indicate SQL syntax issues from the application
• Review database audit logs for unauthorized SELECT queries accessing sensitive tables
• Track network traffic for unusual outbound data transfers that may indicate data exfiltration

How to Mitigate CVE-2024-9813

Immediate Actions Required

• Restrict network access to the Codezips Pharmacy Management System to trusted IP addresses only
• Implement WAF rules to filter SQL injection attempts targeting the vulnerable endpoint
• Review and audit database permissions to minimize potential impact of SQL injection exploitation
• Consider taking the application offline if it processes sensitive healthcare data until a fix is available

Patch Information

No official patch information is currently available from the vendor. Organizations using Codezips Pharmacy Management System 1.0 should monitor the vendor's communications for security updates. Additional technical details are available at the VulDB CTI entry and the VulDB submission.

Workarounds

• Deploy a Web Application Firewall (WAF) configured to detect and block SQL injection patterns
• Implement input validation at the application layer by modifying the PHP code to use prepared statements with parameterized queries
• Apply the principle of least privilege to database accounts used by the application
• Segment the network to isolate the pharmacy management system from critical infrastructure
• Enable verbose logging on both the web server and database to facilitate detection of exploitation attempts
