CVE-2025-41008: Sinturno SQL Injection Vulnerability

CVE-2025-41008 Overview

CVE-2025-41008 is a critical SQL injection vulnerability affecting Sinturno. This vulnerability allows an attacker to retrieve, create, update, and delete databases through the client parameter in the /_adm/scripts/modalReport_data.php endpoint. The flaw represents a classic example of improper input validation leading to complete database compromise.

Critical Impact

Unauthenticated attackers can remotely manipulate database contents, potentially leading to complete data breach, data destruction, or unauthorized access to sensitive information stored in affected Sinturno installations.

Technical Details for CVE-2025-41008

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the Sinturno application's administrative reporting functionality. The vulnerable endpoint /_adm/scripts/modalReport_data.php fails to properly sanitize user-supplied input in the client parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed with the privileges of the database user configured for the application.

The network-accessible nature of this vulnerability combined with no authentication requirements makes it particularly dangerous. An attacker can craft malicious requests to extract sensitive data, modify existing records, insert new data, or delete entire database tables without any prior access to the system.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the modalReport_data.php script. User-controlled input from the client parameter is directly concatenated into SQL query strings without sanitization or escaping, enabling attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack vector is network-based and requires no user interaction or authentication. An attacker can send specially crafted HTTP requests to the /_adm/scripts/modalReport_data.php endpoint with malicious SQL code injected into the client parameter. The vulnerable code processes this input and executes the attacker-controlled SQL against the backend database.

The exploitation typically involves techniques such as UNION-based injection to extract data, boolean-based blind injection to infer database contents, or time-based blind injection when direct output is not available. Depending on the database configuration and privileges, attackers may also be able to escalate to operating system command execution through database-specific features.

Detection Methods for CVE-2025-41008

Indicators of Compromise

• Unusual HTTP requests to /_adm/scripts/modalReport_data.php containing SQL syntax characters such as single quotes, double dashes, UNION, SELECT, or other SQL keywords
• Database error messages in application logs indicating malformed queries
• Unexpected database queries in database audit logs, particularly those involving system tables or bulk data extraction
• Anomalous data modifications, deletions, or new administrative accounts in the database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the client parameter
• Monitor HTTP access logs for requests to the vulnerable endpoint containing encoded or obfuscated SQL injection payloads
• Implement database activity monitoring to alert on unusual query patterns, particularly those accessing sensitive tables or using administrative commands
• Configure intrusion detection systems (IDS) with signatures for common SQL injection techniques

Monitoring Recommendations

• Enable detailed logging on the Sinturno application to capture all requests to administrative endpoints
• Configure database audit logging to track all queries executed against sensitive tables
• Implement real-time alerting for detection of SQL injection patterns in web traffic
• Regularly review access logs for the /_adm/ directory for unauthorized access attempts

How to Mitigate CVE-2025-41008

Immediate Actions Required

• Restrict network access to the /_adm/ directory by implementing IP-based access controls or VPN requirements
• Deploy a Web Application Firewall with SQL injection protection enabled in front of affected Sinturno installations
• Disable or remove the modalReport_data.php script if the reporting functionality is not required
• Review database user permissions and apply the principle of least privilege to limit potential damage from exploitation

Patch Information

No vendor patch information is currently available in the CVE data. Organizations should monitor the INCIBE Security Notice for updates regarding official patches or remediation guidance from the vendor.

Workarounds

• Implement strict input validation on all parameters passed to the modalReport_data.php endpoint
• Deploy a reverse proxy or WAF configured to sanitize or reject requests containing SQL injection patterns
• Restrict access to the administrative interface to trusted IP addresses only
• Consider taking the vulnerable endpoint offline until an official patch is available
• Use database stored procedures with parameterized inputs if modifying the application code is possible

# Example: Restrict access to admin directory using Apache
# Add to .htaccess or Apache configuration
<Directory "/path/to/sinturno/_adm">
    Require ip 192.168.1.0/24
    # Or require VPN access
    # Require ip 10.0.0.0/8
</Directory>
