CVE-2025-49853: ControlID iDSecure SQL Injection Vulnerability

CVE-2025-49853 Overview

CVE-2025-49853 is a critical SQL injection vulnerability affecting ControlID iDSecure On-premises versions 4.7.48.0 and prior. This vulnerability allows an unauthenticated attacker to inject arbitrary SQL syntax into SQL queries, potentially enabling the exfiltration of sensitive information from the underlying database and manipulation of data integrity.

Critical Impact

Unauthenticated attackers can exploit SQL injection to leak arbitrary information and manipulate database queries in access control systems, potentially compromising physical security infrastructure.

Affected Products

Technical Details for CVE-2025-49853

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the ControlID iDSecure On-premises access control software. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating an injection point that attackers can exploit remotely without authentication.

The network-accessible nature of this vulnerability significantly increases its exploitability, as attackers do not require local access or prior authentication to mount an attack. The impact includes potential exposure of highly sensitive access control data, user credentials, and the ability to modify access permissions within the security system.

Given that iDSecure is an access control management platform, successful exploitation could have severe physical security implications, potentially allowing attackers to grant unauthorized building access or disable security controls.

Root Cause

The root cause is improper neutralization of special elements used in SQL commands (CWE-89). The application constructs SQL queries using user-controlled input without adequate input validation or parameterized queries, allowing attackers to inject malicious SQL statements that are then executed by the database engine.

Attack Vector

The attack vector is network-based, requiring no user interaction or prior privileges. An attacker can craft malicious HTTP requests containing SQL injection payloads to exploit vulnerable endpoints in the iDSecure application. The vulnerability allows both data exfiltration through techniques like UNION-based or blind SQL injection, as well as data manipulation through INSERT, UPDATE, or DELETE operations.

SQL injection attacks against this system could employ various techniques including error-based extraction, time-based blind injection, or out-of-band data retrieval depending on the database configuration and network environment. For detailed technical analysis, refer to the CISA ICS Advisory ICSA-25-175-05.

Detection Methods for CVE-2025-49853

Indicators of Compromise

• Unusual SQL error messages in application logs indicating injection attempts
• Unexpected database query patterns or anomalous query execution times
• Unauthorized data access or export activity in database audit logs
• Suspicious HTTP requests containing SQL syntax characters such as single quotes, semicolons, or UNION statements

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the iDSecure application
• Enable database query logging and monitor for anomalous or malformed SQL statements
• Deploy network intrusion detection signatures for common SQL injection attack patterns
• Monitor authentication and access control logs for unauthorized modifications

Monitoring Recommendations

• Review HTTP request logs for payloads containing SQL metacharacters and keywords
• Enable verbose database logging to capture all executed queries for forensic analysis
• Implement alerting on database errors that may indicate injection attempts
• Monitor network traffic to and from the iDSecure server for suspicious patterns

How to Mitigate CVE-2025-49853

Immediate Actions Required

• Restrict network access to the iDSecure application to trusted IP addresses only
• Implement network segmentation to isolate the access control system from untrusted networks
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Review database audit logs for evidence of prior exploitation
• Disable or restrict access to vulnerable endpoints if possible without impacting critical operations

Patch Information

Organizations should consult the CISA ICS Advisory ICSA-25-175-05 for official remediation guidance from ASSA ABLOY and CISA. Contact the vendor directly to obtain security updates for ControlID iDSecure versions newer than 4.7.48.0 that address this vulnerability.

Workarounds

• Place the iDSecure server behind a firewall that restricts access to authorized administrative IP addresses only
• Implement database-level protections including least-privilege access and prepared statements where configurable
• Deploy intrusion prevention systems (IPS) with SQL injection attack signatures
• Consider implementing additional authentication layers such as VPN requirements for administrative access

# Example: Restrict network access to iDSecure server using iptables
# Replace 192.168.1.0/24 with your trusted management network
iptables -A INPUT -p tcp --dport 443 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
