CVE-2024-29727: SportsNET SQL Injection Vulnerability

CVE-2024-29727 Overview

CVE-2024-29727 is a SQL Injection vulnerability affecting SportsNET version 4.0.1. This vulnerability allows an unauthenticated attacker to retrieve, update, and delete all information in the database by sending a specially crafted SQL query to the /app/ax/sendParticipationRemember/ endpoint via the send parameter. The vulnerability stems from improper input validation (CWE-89), allowing malicious SQL statements to be injected and executed against the backend database.

Critical Impact

This SQL injection vulnerability enables complete database compromise, allowing attackers to exfiltrate sensitive data, modify records, or delete entire databases without authentication.

Affected Products

• SportsNET version 4.0.1

Technical Details for CVE-2024-29727

Vulnerability Analysis

This SQL injection vulnerability exists in the SportsNET web application's participation reminder functionality. The vulnerable endpoint /app/ax/sendParticipationRemember/ fails to properly sanitize the send parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are then executed by the database server with the privileges of the application's database user.

The vulnerability is particularly severe because it requires no authentication to exploit and can be triggered remotely over the network. An attacker can leverage this flaw to perform various malicious actions including extracting sensitive user data, modifying database records, escalating privileges within the application, and potentially achieving complete data destruction.

Root Cause

The root cause of this vulnerability is improper neutralization of special elements used in an SQL command (CWE-89). The application directly incorporates user-supplied input from the send parameter into database queries without proper sanitization, parameterization, or the use of prepared statements. This allows attackers to break out of the intended query structure and inject their own SQL commands.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft malicious HTTP requests to the vulnerable endpoint, injecting SQL payloads through the send parameter. The attack complexity is low, as standard SQL injection techniques can be employed to exploit this vulnerability.

The exploitation flow involves sending specially crafted requests to the sendParticipationRemember endpoint where the send parameter contains SQL injection payloads. These payloads can use techniques such as UNION-based injection to extract data, boolean-based blind injection to infer database contents, or stacked queries to execute arbitrary SQL commands including data modification and deletion.

Detection Methods for CVE-2024-29727

Indicators of Compromise

• Unusual HTTP requests to /app/ax/sendParticipationRemember/ containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION statements
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries or commands in database audit logs
• Anomalous data access patterns or bulk data extraction from the database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to the affected endpoint
• Implement application-level logging for all requests to /app/ax/sendParticipationRemember/ and monitor for suspicious parameter values
• Enable database query logging and alert on unusual query patterns, particularly those containing injection signatures
• Use intrusion detection systems (IDS) with SQL injection detection signatures

Monitoring Recommendations

• Monitor web server access logs for requests to the vulnerable endpoint containing encoded or obfuscated SQL injection payloads
• Set up alerts for database errors that may indicate injection attempts
• Track data access patterns and alert on unusual bulk queries or data exfiltration attempts
• Implement real-time monitoring for changes to critical database tables

How to Mitigate CVE-2024-29727

Immediate Actions Required

• Restrict network access to the affected SportsNET application if feasible until a patch is applied
• Implement WAF rules to block requests containing SQL injection payloads to the vulnerable endpoint
• Review database logs for evidence of prior exploitation attempts
• Consider temporarily disabling the /app/ax/sendParticipationRemember/ functionality if business operations allow

Patch Information

Review the INCIBE Security Notice for official vendor guidance and patch availability. Contact the SportsNET vendor directly for information regarding security updates addressing this vulnerability.

Workarounds

• Implement input validation at the application layer to sanitize the send parameter before processing
• Deploy a WAF with SQL injection detection and prevention capabilities in front of the application
• Use database connection accounts with minimal required privileges to limit the impact of successful exploitation
• Consider network segmentation to restrict access to the SportsNET application to trusted networks only
