CVE-2026-2620 Overview
A SQL injection vulnerability has been identified in Huace Monitoring and Early Warning System version 2.2. This vulnerability affects the /Web/SysManage/ProjectRole.aspx file, where manipulation of the ID parameter enables attackers to execute arbitrary SQL commands against the underlying database. The exploit has been publicly disclosed and can be launched remotely without authentication. The vendor was contacted about this vulnerability but did not respond.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive data in the database, potentially compromising the entire monitoring and early warning system.

Technical Details for CVE-2026-2620
Vulnerability Analysis
This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as injection. The affected endpoint /Web/SysManage/ProjectRole.aspx fails to properly sanitize user-supplied input in the ID parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL code that gets executed by the database server.
The vulnerability is remotely exploitable without requiring authentication or user interaction, making it particularly dangerous for internet-facing deployments of the Huace Monitoring and Early Warning System. The public availability of exploit information increases the likelihood of active exploitation attempts.
Root Cause
The root cause stems from insufficient input validation and improper neutralization of special characters in the ID parameter. The application directly concatenates user input into SQL queries without using parameterized queries or prepared statements, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.
Attack Vector
The attack is network-based, requiring only HTTP access to the vulnerable endpoint. An attacker can craft malicious requests to /Web/SysManage/ProjectRole.aspx with specially crafted ID parameter values containing SQL syntax. Since the vulnerability requires no authentication or user interaction, any attacker with network access to the application can attempt exploitation.
The SQL injection can potentially be used to extract sensitive information from the database, modify or delete data, bypass authentication mechanisms, or in some cases escalate to operating system command execution depending on database configuration and privileges.
Detection Methods for CVE-2026-2620
Indicators of Compromise
- HTTP requests to /Web/SysManage/ProjectRole.aspx containing SQL syntax in the ID parameter (e.g., UNION SELECT, OR 1=1, single quotes)
- Unusual database query patterns or errors in application logs
- Unexpected data extraction or modifications in the monitoring system database
- Web server access logs showing repeated requests with varying SQL payloads to the affected endpoint
Detection Strategies
- Deploy web application firewall (WAF) rules to detect and block common SQL injection patterns in HTTP parameters
- Monitor database query logs for anomalous queries originating from the web application
- Implement intrusion detection system (IDS) signatures for SQL injection attack patterns targeting ASP.NET applications
- Review web server access logs for requests containing encoded SQL characters or known injection payloads
Monitoring Recommendations
- Enable verbose logging on the Huace Monitoring and Early Warning System web server
- Configure database audit logging to capture all queries executed against the backend database
- Set up alerts for unusual database access patterns or query failures
- Monitor network traffic for signs of data exfiltration following potential exploitation
How to Mitigate CVE-2026-2620
Immediate Actions Required
- Restrict network access to the Huace Monitoring and Early Warning System to trusted IP addresses only
- Deploy a web application firewall (WAF) with SQL injection protection rules in front of the application
- Consider taking the affected system offline if it is internet-facing until remediation is available
- Review database logs for signs of prior exploitation and assess potential data compromise
Patch Information
No official patch information is currently available from the vendor. According to the vulnerability disclosure, the vendor was contacted but did not respond. Organizations should monitor vendor communications and apply patches when they become available. For additional technical details, refer to the GitHub SQL Vulnerability Report and VulDB #346271.
Workarounds
- Implement network segmentation to isolate the vulnerable system from untrusted networks
- Use a reverse proxy or WAF to filter and sanitize the ID parameter before it reaches the application
- Restrict database user privileges to minimum required operations to limit impact of successful exploitation
- If source code access is available, implement parameterized queries or prepared statements for the affected endpoint
