CVE-2024-29724: Sportsnet SQL Injection Vulnerability

CVE-2024-29724 Overview

CVE-2024-29724 is a critical SQL injection vulnerability affecting SportsNET version 4.0.1. This vulnerability exists in the registration endpoint (/ax/registerSp/) and can be exploited through the idDesafio parameter. An attacker can send specially crafted SQL queries to retrieve, update, and delete all information in the database, leading to complete database compromise.

Critical Impact

This SQL injection vulnerability allows unauthenticated remote attackers to fully compromise the database, enabling data theft, modification, and deletion of all stored information.

Affected Products

• SportsNET version 4.0.1
• SportsNET web application registration functionality
• Systems utilizing the /ax/registerSp/ endpoint

Technical Details for CVE-2024-29724

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The vulnerable application fails to properly sanitize user-supplied input in the idDesafio parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that execute with the privileges of the database user configured for the application.

The network-accessible nature of this vulnerability means exploitation requires no authentication or user interaction. Successful exploitation can result in unauthorized access to sensitive data (confidentiality breach), modification of database records (integrity breach), and deletion of data (availability breach).

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements in the registration functionality. The idDesafio parameter value is directly concatenated or interpolated into SQL queries without proper sanitization, allowing malicious SQL code to be executed against the backend database.

Attack Vector

The attack is conducted remotely over the network by sending HTTP requests to the vulnerable endpoint at /ax/registerSp/. An attacker crafts malicious input containing SQL syntax in the idDesafio parameter. When the server processes this request, the unsanitized input is incorporated into a database query, allowing the attacker to manipulate the query logic.

Common attack techniques include:

• Union-based SQL injection to extract data from other tables
• Error-based SQL injection to enumerate database structure
• Time-based blind SQL injection for data extraction when direct output is not visible
• Stacked queries to execute multiple SQL statements including UPDATE and DELETE operations

For detailed technical information, see the INCIBE CERT Security Notice.

Detection Methods for CVE-2024-29724

Indicators of Compromise

• Anomalous HTTP requests to /ax/registerSp/ containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Database error messages in application logs indicating malformed queries
• Unexpected database activity including bulk data exports or schema enumeration queries
• Web application firewall alerts for SQL injection pattern matches on the idDesafio parameter

Detection Strategies

• Deploy web application firewalls (WAF) with SQL injection detection rules targeting the /ax/registerSp/ endpoint
• Implement database activity monitoring to detect unusual query patterns or unauthorized data access
• Configure intrusion detection systems to alert on SQL injection payload signatures in HTTP traffic
• Enable detailed logging on the SportsNET application and database for forensic analysis

Monitoring Recommendations

• Monitor HTTP request logs for payloads containing SQL keywords (SELECT, UNION, INSERT, UPDATE, DELETE, DROP) in the idDesafio parameter
• Set up alerts for database query failures or syntax errors that may indicate injection attempts
• Track database user session activity for bulk data retrieval operations
• Review access logs for requests originating from suspicious IP addresses or geolocations

How to Mitigate CVE-2024-29724

Immediate Actions Required

• Restrict network access to the vulnerable /ax/registerSp/ endpoint using firewall rules or access control lists
• Deploy a web application firewall with strict SQL injection blocking rules
• If possible, disable the registration functionality until a patch is applied
• Audit database access logs for signs of prior exploitation and potential data breach

Patch Information

At the time of publication, no official vendor patch has been confirmed in the available CVE data. Organizations should monitor the INCIBE CERT Security Notice and vendor communications for updates regarding security patches for SportsNET version 4.0.1.

Workarounds

• Implement input validation at the application layer to reject requests containing SQL metacharacters in the idDesafio parameter
• Use a WAF or reverse proxy to filter and block SQL injection patterns
• Apply database account principle of least privilege to limit the impact of successful exploitation
• Consider network segmentation to isolate the SportsNET application from critical infrastructure
