CVE-2024-2934: Todo List Kanban Board SQLi Vulnerability

CVE-2024-2934 Overview

A critical SQL injection vulnerability has been discovered in SourceCodester Todo List in Kanban Board version 1.0. The vulnerability exists in the file /endpoint/delete-todo.php where improper handling of the list parameter allows attackers to inject malicious SQL commands. This flaw can be exploited remotely without authentication, potentially leading to unauthorized data access, modification, or complete database compromise.

Critical Impact

Unauthenticated remote attackers can execute arbitrary SQL commands through the list parameter in /endpoint/delete-todo.php, enabling full database compromise including data theft, modification, and deletion.

Technical Details for CVE-2024-2934

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the delete-todo.php endpoint. The application fails to properly sanitize user-supplied input passed through the list parameter before incorporating it into SQL queries. This allows attackers to manipulate the query structure by injecting malicious SQL statements.

The vulnerability affects the delete functionality of the Kanban board application, where the list parameter is intended to identify which todo item should be removed. Without proper parameterized queries or input sanitization, an attacker can craft payloads that extend beyond the intended query logic.

Since the application does not require authentication to access the vulnerable endpoint, any remote attacker with network access can exploit this flaw. Successful exploitation could allow attackers to extract sensitive data from the database, modify or delete records, and potentially gain further access to the underlying system depending on database permissions and configuration.

Root Cause

The root cause of CVE-2024-2934 is the direct concatenation of user-supplied input into SQL queries without proper sanitization or the use of prepared statements. The delete-todo.php file processes the list parameter and builds SQL queries dynamically, creating a classic SQL injection attack surface. This violates the secure coding principle of treating all user input as untrusted and demonstrates the absence of parameterized query implementation.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker sends a malicious HTTP request to the /endpoint/delete-todo.php endpoint with a crafted list parameter containing SQL injection payloads. The server processes this input and executes the injected SQL commands against the backend database.

The vulnerability is accessible through standard HTTP requests, making it trivial to exploit using common tools like curl, web browsers, or automated SQL injection tools. The exploit methodology and proof-of-concept have been publicly documented, as referenced in the GitHub SQL Injection Documentation.

Detection Methods for CVE-2024-2934

Indicators of Compromise

• Unusual or malformed requests to /endpoint/delete-todo.php containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION statements
• Database error messages in application logs indicating SQL syntax errors or unexpected query behavior
• Unexpected data exfiltration or database dump activities in network traffic logs
• Evidence of time-based or error-based SQL injection payloads in web server access logs

Detection Strategies

• Deploy Web Application Firewalls (WAF) with SQL injection detection rules targeting the list parameter
• Implement application-level logging to capture and alert on suspicious parameter values
• Monitor database query logs for anomalous or unauthorized SELECT, INSERT, UPDATE, or DELETE operations
• Use security information and event management (SIEM) solutions to correlate web traffic anomalies with database activities

Monitoring Recommendations

• Enable verbose logging on the web application to capture full request details including parameter values
• Configure database audit logging to track all queries executed against sensitive tables
• Set up automated alerts for detection of SQL injection patterns in request parameters
• Regularly review web server access logs for reconnaissance or exploitation attempts targeting /endpoint/delete-todo.php

How to Mitigate CVE-2024-2934

Immediate Actions Required

• Remove or disable the /endpoint/delete-todo.php endpoint if not critical to operations until a fix is applied
• Implement a Web Application Firewall (WAF) rule to block requests containing SQL injection payloads in the list parameter
• Restrict network access to the application to trusted IP addresses only
• Review database user permissions and apply the principle of least privilege to minimize potential damage from exploitation

Patch Information

As of the last NVD update on 2025-02-18, no official vendor patch has been released for this vulnerability. SourceCodester Todo List in Kanban Board 1.0 users should consider discontinuing use of this application or implementing the workarounds described below. Monitor VulDB #258013 for updates regarding patches or fixes.

Workarounds

• Modify the vulnerable delete-todo.php file to use prepared statements (parameterized queries) with PDO or MySQLi
• Implement server-side input validation to reject any list parameter values containing non-numeric characters
• Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
• Consider replacing the vulnerable application with a maintained alternative that follows secure coding practices
