CVE-2025-11253: Netty ERP SQL Injection Vulnerability

CVE-2025-11253 Overview

CVE-2025-11253 is an SQL Injection vulnerability discovered in Aksis Technology Inc. Netty ERP system. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL queries through network-accessible interfaces. This type of vulnerability (CWE-89) enables unauthorized database manipulation, potentially leading to data exfiltration, data modification, and complete system compromise.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the backend database, potentially compromising all stored data, bypassing authentication mechanisms, and gaining administrative access to the ERP system.

Affected Products

• Netty ERP versions before V.1.1000

Technical Details for CVE-2025-11253

Vulnerability Analysis

This SQL Injection vulnerability exists in Aksis Technology Inc. Netty ERP, an enterprise resource planning system. The vulnerability allows remote attackers to inject malicious SQL statements through user-controllable input fields that are not properly sanitized before being incorporated into database queries. Because the attack can be executed remotely over the network without requiring authentication or user interaction, attackers can exploit this vulnerability with minimal effort to gain unauthorized access to sensitive business data stored in the ERP system.

The impact of successful exploitation is significant—attackers can read, modify, or delete arbitrary data in the database, potentially including financial records, customer information, employee data, and other sensitive business intelligence. In some cases, SQL Injection can be leveraged to achieve remote code execution on the database server or underlying operating system.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize or parameterize user-supplied input before incorporating it into SQL queries. The application directly concatenates user input into SQL statements, allowing special SQL characters and commands to be interpreted as part of the query rather than as data. This is a classic example of CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Attack Vector

The attack is network-based, requiring no privileges or user interaction. An attacker can send specially crafted HTTP requests to the Netty ERP application containing malicious SQL payloads. These payloads may include:

• Union-based injection to extract data from other tables
• Boolean-based blind injection to enumerate database contents
• Time-based blind injection for covert data extraction
• Stacked queries to execute multiple SQL statements including INSERT, UPDATE, or DELETE operations

For technical details regarding exploitation, refer to the USOM Security Notification TR-25-0359.

Detection Methods for CVE-2025-11253

Indicators of Compromise

• Unusual database query patterns or errors in application logs indicating SQL syntax errors
• Unexpected data modifications or deletions in ERP database tables
• Unauthorized access to sensitive records or administrative functions
• Database performance degradation due to malicious query execution
• Web application firewall (WAF) alerts for SQL injection patterns

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection attempts targeting Netty ERP endpoints
• Implement database activity monitoring (DAM) to identify anomalous query patterns
• Review application and web server logs for suspicious input strings containing SQL keywords (SELECT, UNION, INSERT, DROP, etc.)
• Monitor for authentication bypasses or privilege escalation events within the ERP system

Monitoring Recommendations

• Enable detailed logging on the Netty ERP application and associated database servers
• Configure alerts for failed login attempts and authentication anomalies
• Implement intrusion detection system (IDS) signatures for SQL injection payloads
• Regularly audit database access patterns and user activities for signs of compromise

How to Mitigate CVE-2025-11253

Immediate Actions Required

• Update Netty ERP to version V.1.1000 or later immediately
• Implement web application firewall (WAF) rules to filter SQL injection attacks
• Restrict network access to the Netty ERP application to authorized users only
• Review database logs for signs of previous exploitation attempts
• Ensure database accounts used by the application follow the principle of least privilege

Patch Information

Aksis Technology Inc. has addressed this vulnerability in Netty ERP version V.1.1000. Organizations should upgrade to this version or later to remediate the SQL Injection vulnerability. For additional details, consult the USOM Security Notification TR-25-0359.

Workarounds

• Deploy a web application firewall (WAF) with SQL injection detection rules in front of the Netty ERP application
• Implement network segmentation to limit access to the ERP system from untrusted networks
• Apply input validation at the network edge using a reverse proxy or API gateway
• Disable or restrict access to vulnerable endpoints until patching can be completed
• Consider taking the application offline if critical data is at risk and patching cannot be performed immediately

# Example WAF rule for ModSecurity to block common SQL injection patterns
