CVE-2024-0287: Kashipara Food Management SQLi Flaw

CVE-2024-0287 Overview

A critical SQL injection vulnerability has been identified in Kashipara Food Management System version 1.0. The vulnerability exists in the itemBillPdf.php file, where the printid parameter is not properly sanitized before being used in database queries. This allows remote attackers to execute arbitrary SQL commands against the backend database without requiring any authentication or user interaction.

Critical Impact

This vulnerability enables unauthenticated remote attackers to extract sensitive data, modify or delete database contents, and potentially achieve full system compromise through database server exploitation.

Technical Details for CVE-2024-0287

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) occurs in the itemBillPdf.php file of the Kashipara Food Management System. The application fails to properly validate, filter, or parameterize user-supplied input before incorporating it into SQL queries. When users interact with the billing PDF generation functionality, the printid argument is directly concatenated into SQL statements without any sanitization.

The vulnerability is particularly severe because it requires no authentication to exploit. An attacker can craft malicious requests containing SQL metacharacters and commands that will be executed by the database server with the application's privileges. This could lead to unauthorized data disclosure, data manipulation, or in some configurations, command execution on the underlying operating system.

Root Cause

The root cause of this vulnerability is improper input validation and the use of dynamic SQL query construction. The printid parameter received from user input is directly embedded into SQL queries without using prepared statements, parameterized queries, or adequate input sanitization. This is a classic example of trusting user-supplied data in a security-sensitive context.

Attack Vector

The vulnerability can be exploited remotely over the network. An attacker needs only to send a specially crafted HTTP request to the itemBillPdf.php endpoint with a malicious printid parameter value. The attack requires no privileges or authentication, and no user interaction is needed for exploitation.

The exploitation typically involves injecting SQL syntax such as single quotes, UNION statements, or boolean-based payloads to manipulate query logic. For example, an attacker could append SQL commands to extract data from other tables, enumerate database structure, or bypass application logic entirely.

Technical details and proof-of-concept information can be found in the GitHub SQL Injection Vulnerability documentation.

Detection Methods for CVE-2024-0287

Indicators of Compromise

• Unusual HTTP requests to itemBillPdf.php containing SQL metacharacters (single quotes, double dashes, UNION, SELECT, etc.) in the printid parameter
• Database error messages appearing in application logs or HTTP responses indicating malformed SQL queries
• Unexpected database queries or access patterns targeting tables outside normal application scope
• Evidence of data exfiltration through time-based or error-based SQL injection techniques

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters targeting itemBillPdf.php
• Implement database activity monitoring to detect anomalous queries, especially those containing UNION statements, stacked queries, or information schema access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Review web server access logs for requests with suspicious printid parameter values

Monitoring Recommendations

• Enable verbose logging on the database server to capture all queries executed by the Food Management System application
• Set up alerts for failed authentication attempts or database errors that may indicate SQL injection probing
• Monitor for unusual data access patterns, particularly bulk data retrieval or access to sensitive tables
• Implement real-time log analysis to correlate web requests with database activity

How to Mitigate CVE-2024-0287

Immediate Actions Required

• Take the Kashipara Food Management System offline or restrict network access until a patch is applied
• Implement a Web Application Firewall (WAF) with SQL injection blocking rules as a temporary protective measure
• Review database access logs to determine if exploitation has already occurred
• Consider isolating the database server from other network resources to limit potential lateral movement

Patch Information

At the time of publication, no official patch has been released by Kashipara for this vulnerability. Organizations should monitor the vendor's official channels for security updates. In the absence of a vendor patch, implementing the workarounds below is strongly recommended.

For additional vulnerability details, see VulDB #249848.

Workarounds

• Implement input validation on the printid parameter to accept only numeric values
• Modify the application code to use prepared statements or parameterized queries for all database interactions
• Deploy a reverse proxy or WAF configured to filter SQL injection attempts targeting the itemBillPdf.php endpoint
• Restrict database user privileges used by the application to minimum required permissions (principle of least privilege)

# Example: Block suspicious requests at the web server level (Apache .htaccess)
# Add to .htaccess or virtual host configuration
<IfModule mod_rewrite.c>
    RewriteEngine On
    # Block requests with common SQL injection patterns in printid
    RewriteCond %{QUERY_STRING} printid=.*(\%27|\'|--|union|select|insert|drop|update) [NC]
    RewriteRule ^itemBillPdf\.php$ - [F,L]
</IfModule>
