CVE-2024-29730: SportsNET SQL Injection Vulnerability

CVE-2024-29730 Overview

CVE-2024-29730 is a critical SQL injection vulnerability affecting SportsNET version 4.0.1. This vulnerability exists in the web application's consejoRandom endpoint, specifically within the idCat parameter. An attacker can exploit this flaw by sending specially crafted SQL queries to retrieve, update, and delete all information stored in the backend database. The vulnerability requires no authentication and can be exploited remotely over the network without user interaction.

Critical Impact

Successful exploitation allows complete database compromise including unauthorized data retrieval, modification, and deletion of all records in the SportsNET application database.

Affected Products

• SportsNET version 4.0.1

Technical Details for CVE-2024-29730

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the SportsNET web application's consejoRandom endpoint. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL statements through the idCat parameter. The flaw is particularly severe because it requires no authentication, can be exploited remotely, and provides complete access to the underlying database with read, write, and delete capabilities.

The attack surface is exposed through the URL path /app/ax/consejoRandom/ where the idCat parameter accepts user-controlled input that is directly incorporated into SQL queries without proper sanitization or parameterization.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and sanitization on the idCat parameter within the consejoRandom endpoint. The application fails to implement parameterized queries or prepared statements, allowing user-supplied input to be directly concatenated into SQL statements. This enables attackers to escape the intended query structure and execute arbitrary SQL commands against the database.

Attack Vector

The attack is conducted remotely over the network by sending HTTP requests to the vulnerable endpoint with malicious SQL payloads in the idCat parameter. Since no authentication is required, any remote attacker with network access to the SportsNET application can exploit this vulnerability. The attacker can craft SQL injection payloads to perform various database operations including:

• Data Exfiltration: Using UNION-based or blind SQL injection techniques to extract sensitive data from database tables
• Data Manipulation: Modifying existing records or inserting malicious data
• Data Destruction: Deleting database records or dropping entire tables
• Privilege Escalation: Potentially accessing database administrative functions depending on database permissions

The vulnerability is accessible through the endpoint pattern: https://[target]/app/ax/consejoRandom/?idCat=[MALICIOUS_PAYLOAD]

For technical details on exploitation patterns, refer to the INCIBE Security Notice.

Detection Methods for CVE-2024-29730

Indicators of Compromise

• Unusual HTTP requests to the /app/ax/consejoRandom/ endpoint containing SQL syntax characters such as single quotes, double dashes, UNION statements, or semicolons
• Database logs showing unexpected queries with SQL injection patterns originating from web application connections
• Abnormal database activity including bulk data exports, unexpected DELETE or UPDATE operations, or attempts to access system tables
• Web server access logs containing URL-encoded SQL keywords targeting the idCat parameter

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the idCat parameter and other user inputs
• Implement database activity monitoring to identify anomalous query patterns, unauthorized data access, or suspicious command execution
• Enable detailed application logging for the consejoRandom endpoint and analyze logs for injection attempts
• Use network intrusion detection systems (IDS) with SQL injection signature rules to monitor traffic to SportsNET applications

Monitoring Recommendations

• Continuously monitor HTTP traffic to SportsNET applications for SQL injection payload signatures
• Set up alerting for database queries containing suspicious patterns such as UNION SELECT, OR 1=1, or attempts to access information_schema
• Review web server access logs regularly for reconnaissance activity targeting vulnerable endpoints
• Implement real-time security monitoring with SentinelOne Singularity to detect exploitation attempts and lateral movement following database compromise

How to Mitigate CVE-2024-29730

Immediate Actions Required

• Restrict network access to the SportsNET application to only trusted IP addresses and networks
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the affected application
• Disable or remove the vulnerable /app/ax/consejoRandom/ endpoint if it is not critical to operations
• Review database user permissions and apply the principle of least privilege to limit potential damage from exploitation
• Implement database backups immediately to protect against data loss from potential attacks

Patch Information

As of the last NVD update on 2024-08-30, no vendor patch information is available. Organizations should monitor the INCIBE Security Notice for updates on official fixes from the vendor. Contact SportsNET directly for guidance on available patches or security updates for version 4.0.1.

Workarounds

• Implement input validation at the application level by using parameterized queries or prepared statements for all database operations
• Deploy a reverse proxy with SQL injection filtering capabilities to sanitize requests before they reach the application
• Use database stored procedures with proper input handling instead of dynamic SQL queries
• Consider temporarily taking the affected endpoint offline until a vendor patch is available
• Implement network segmentation to isolate the SportsNET application and database from critical systems
