CVE-2025-10266: NUP Pro SQL Injection Vulnerability

CVE-2025-10266 Overview

CVE-2025-10266 is a critical SQL Injection vulnerability discovered in NUP Pro, developed by NewType Infortech. This vulnerability allows unauthenticated remote attackers to inject arbitrary SQL commands, enabling them to read, modify, and delete database contents. The lack of authentication requirement makes this vulnerability particularly dangerous, as any network-accessible attacker can exploit it without credentials.

Critical Impact

Unauthenticated attackers can fully compromise database integrity and confidentiality by injecting arbitrary SQL commands to read, modify, or delete all database contents.

Technical Details for CVE-2025-10266

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in the NUP Pro application where user-supplied input is improperly incorporated into SQL queries without adequate sanitization or parameterization. The vulnerability is exploitable over the network with no authentication required, meaning any remote attacker with network access to the vulnerable application can craft malicious SQL statements to manipulate the backend database.

The exploitation does not require any user interaction, making it highly reliable for attackers. A successful exploit grants the attacker complete control over database operations including the ability to extract sensitive data, modify records, and potentially delete entire database contents.

Root Cause

The root cause of this vulnerability is improper neutralization of special elements used in SQL commands (CWE-89). The application fails to properly validate, sanitize, or parameterize user-supplied input before incorporating it into SQL queries. This allows attackers to inject malicious SQL syntax that the database interprets and executes as part of the intended query.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable application endpoints. The malicious input is processed by the application and passed directly to the database engine, allowing the attacker to:

1. Extract sensitive data from database tables using UNION-based or error-based injection techniques
2. Modify existing records or insert new malicious data
3. Delete database contents, causing data loss and service disruption
4. Potentially escalate to operating system command execution depending on database configuration and privileges

Detection Methods for CVE-2025-10266

Indicators of Compromise

• Unusual database query patterns containing SQL injection payloads such as UNION SELECT, OR 1=1, single quotes, or comment sequences
• Unexpected database errors or error messages in application logs indicating malformed SQL syntax
• Anomalous data access patterns showing bulk extraction of database records
• Database audit logs showing queries executed outside normal application behavior

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests
• Enable database activity monitoring to alert on suspicious queries containing injection signatures
• Configure application logging to capture all input parameters and correlate with database query logs
• Deploy network intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Monitor database query logs for unusual patterns including UNION, SELECT, INSERT, UPDATE, DELETE statements with unexpected syntax
• Set up alerts for database errors that may indicate exploitation attempts
• Track and alert on abnormal data access volumes or patterns from application service accounts
• Implement real-time monitoring of web server access logs for requests containing SQL injection payloads

How to Mitigate CVE-2025-10266

Immediate Actions Required

• Contact NewType Infortech for available security patches or updates for NUP Pro
• Implement Web Application Firewall (WAF) rules to filter SQL injection attempts
• Restrict network access to the vulnerable application to trusted IP ranges only
• Review and restrict database user permissions to minimum required privileges

Patch Information

Organizations should consult the TWCERT Security Advisory and contact NewType Infortech directly for official patch availability and installation guidance. Apply vendor-provided patches as soon as they become available.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection and blocking capabilities in front of the vulnerable application
• Implement network segmentation to limit access to NUP Pro from untrusted networks
• Configure database user accounts used by the application with least-privilege permissions, restricting DELETE and schema modification rights
• Enable database query logging and monitoring to detect exploitation attempts while awaiting a permanent fix
