CVE-2025-0455: airPASS SQL Injection Vulnerability

CVE-2025-0455 Overview

The airPASS application from NetVision Information contains a SQL Injection vulnerability that allows unauthenticated remote attackers to inject arbitrary SQL commands. This critical flaw enables adversaries to read, modify, and delete database contents without requiring any prior authentication or user interaction.

Critical Impact

Unauthenticated attackers can completely compromise database confidentiality, integrity, and availability through arbitrary SQL command injection, potentially leading to full data breach, data manipulation, or complete data destruction.

Affected Products

• NetVision airPASS (all versions presumed vulnerable)

Technical Details for CVE-2025-0455

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) in NetVision airPASS represents a fundamental failure in input validation and parameterized query implementation. The vulnerability allows attackers to manipulate SQL queries by injecting malicious commands through user-controllable input fields. Since the vulnerability requires no authentication, any network-accessible attacker can exploit this flaw to interact directly with the backend database.

The attack surface is network-based with no complexity barriers, meaning exploitation is straightforward for even moderately skilled attackers. The complete lack of authentication requirements significantly amplifies the risk, as there are no gatekeeping mechanisms to prevent unauthorized access to the vulnerable functionality.

Root Cause

The root cause of this vulnerability is improper neutralization of special elements used in SQL commands (CWE-89: Improper Neutralization of Special Elements used in an SQL Command). The airPASS application fails to properly sanitize, validate, or parameterize user-supplied input before incorporating it into SQL queries. This allows attackers to escape the intended query context and inject their own SQL statements.

Attack Vector

The attack vector is network-based, allowing remote unauthenticated attackers to exploit this vulnerability. Attackers can craft malicious HTTP requests containing SQL injection payloads directed at vulnerable endpoints in the airPASS application. The injected SQL commands execute with the privileges of the database user configured for the application, potentially granting full read/write/delete access to all database contents.

Exploitation typically involves identifying input fields that are incorporated into SQL queries, then crafting payloads that break out of the intended query structure. Common techniques include UNION-based injection to extract data, boolean-based blind injection to enumerate information, and stacked queries to execute arbitrary database commands.

Detection Methods for CVE-2025-0455

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or HTTP responses
• Unexpected database queries containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, or comment sequences (--, /**/)
• Abnormal database activity such as bulk data extraction, unauthorized data modifications, or schema enumeration
• Suspicious HTTP requests containing SQL metacharacters (single quotes, double dashes, semicolons) in parameter values

Detection Strategies

• Deploy web application firewalls (WAF) with SQL injection detection rules to monitor and block malicious requests targeting airPASS endpoints
• Implement database activity monitoring to detect anomalous query patterns, including unusual SELECT statements, unauthorized data access, or bulk data extraction
• Enable verbose logging on web servers and database servers to capture request details and query execution for forensic analysis
• Configure intrusion detection systems (IDS) with signatures for common SQL injection patterns and payloads

Monitoring Recommendations

• Monitor database logs for failed authentication attempts, privilege escalation attempts, and access to sensitive tables
• Establish baseline normal query patterns and alert on deviations that may indicate SQL injection exploitation
• Track network traffic to database servers for connections from unexpected sources or unusual data transfer volumes
• Implement real-time alerting for SQL error conditions that may indicate injection attempts

How to Mitigate CVE-2025-0455

Immediate Actions Required

• Restrict network access to the airPASS application to trusted IP ranges only using firewall rules
• Implement a web application firewall (WAF) with strict SQL injection filtering rules in front of the airPASS deployment
• Review database permissions and apply principle of least privilege to the application's database user account
• Enable comprehensive logging on the airPASS application and associated database to detect exploitation attempts

Patch Information

Organizations should monitor NetVision Information communications and the TW-CERT Security Advisory for official patch releases addressing this vulnerability. Contact NetVision Information directly for updated software versions that remediate CVE-2025-0455.

Workarounds

• Deploy network segmentation to isolate the airPASS application from untrusted networks and limit exposure
• Implement strict input validation at the network perimeter using WAF rules to block SQL injection payloads
• Configure database firewall solutions to monitor and restrict SQL command execution patterns
• Consider temporarily disabling public network access to the airPASS application until a vendor patch is available
