CVE-2024-50717: Smart Agent SQL Injection Vulnerability

CVE-2024-50717 Overview

CVE-2024-50717 is a SQL injection vulnerability discovered in Smart Agent v.1.1.0 that allows a remote attacker to execute arbitrary code via the client parameter in the /recuperaLog.php component. This vulnerability enables unauthenticated attackers to manipulate database queries, potentially leading to complete compromise of the underlying database and system.

Critical Impact

Unauthenticated remote attackers can execute arbitrary SQL commands, potentially gaining full control over the database, exfiltrating sensitive data, or executing system commands through the affected Smart Agent application.

Affected Products

• Smarts-srl Smart Agent v1.1.0 Pro Edition
• Smarts-srl Smart Agent v1.1.0 QoE Edition

Technical Details for CVE-2024-50717

Vulnerability Analysis

This SQL injection vulnerability exists in the /recuperaLog.php component of Smart Agent v1.1.0. The application fails to properly sanitize the client parameter before incorporating it into SQL queries, allowing attackers to inject malicious SQL statements. Since this vulnerability is exploitable over the network without authentication or user interaction, attackers can remotely compromise the database with minimal effort. Successful exploitation could result in unauthorized data access, data modification, data deletion, or in some database configurations, execution of operating system commands.

Root Cause

The root cause of CVE-2024-50717 is improper input validation in the /recuperaLog.php endpoint. The client parameter is directly concatenated or improperly parameterized within SQL queries, violating secure coding practices. This lack of input sanitization allows attacker-controlled data to be interpreted as SQL commands rather than data values, enabling classic SQL injection attacks.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /recuperaLog.php endpoint with SQL injection payloads in the client parameter. The vulnerable endpoint processes the parameter without adequate validation, passing the malicious input directly to the database engine.

The exploitation typically involves:

1. Identifying the vulnerable /recuperaLog.php endpoint
2. Crafting SQL injection payloads in the client parameter
3. Sending HTTP requests with malicious payloads to extract data, modify records, or potentially execute system commands depending on database privileges

Detection Methods for CVE-2024-50717

Indicators of Compromise

• HTTP requests to /recuperaLog.php containing SQL metacharacters such as single quotes, semicolons, or UNION keywords in the client parameter
• Unusual database query patterns or errors in application logs originating from the Smart Agent application
• Unexpected database modifications or data exfiltration activity
• Web server logs showing requests with encoded SQL injection payloads targeting the client parameter

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the /recuperaLog.php endpoint
• Deploy database activity monitoring to identify anomalous queries originating from the Smart Agent application
• Configure intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Enable detailed logging for the Smart Agent application and monitor for suspicious parameter values

Monitoring Recommendations

• Monitor HTTP request logs for the /recuperaLog.php endpoint with particular attention to the client parameter
• Set up alerts for database error messages that may indicate failed SQL injection attempts
• Track unusual database access patterns or queries that deviate from normal application behavior
• Review authentication logs for signs of privilege escalation following potential exploitation

How to Mitigate CVE-2024-50717

Immediate Actions Required

• Restrict network access to the Smart Agent application to trusted IP addresses only
• Implement a web application firewall (WAF) with SQL injection protection rules
• If possible, disable or remove access to the /recuperaLog.php endpoint until a patch is available
• Review database user privileges and apply the principle of least privilege to limit potential impact

Patch Information

At the time of publication, no official vendor patch information has been released. Organizations should monitor the SmartS SRL Homepage for security updates and patch availability. Contact the vendor directly for remediation guidance regarding Smart Agent v1.1.0.

Workarounds

• Deploy input validation at the network perimeter using a WAF to filter SQL injection patterns
• Implement network segmentation to isolate the Smart Agent application from critical systems
• Apply database-level protections such as stored procedures and parameterized queries where possible
• Consider disabling the vulnerable /recuperaLog.php component if it is not essential for operations

# Example WAF rule to block SQL injection attempts on the vulnerable endpoint
# ModSecurity rule example
SecRule REQUEST_URI "@contains /recuperaLog.php" \
    "id:100001,phase:2,deny,status:403,\
    chain"
    SecRule ARGS:client "@detectSQLi" \
        "log,msg:'SQL Injection attempt blocked on recuperaLog.php'"
