CVE-2025-52577
📋 TL;DR
This vulnerability in Advantech iView allows authenticated attackers with user-level privileges to perform SQL injection through NetworkServlet.archiveTrapRange(), potentially leading to remote code execution as the 'nt authority\local service' account. Organizations using vulnerable versions of Advantech iView are affected.
💻 Affected Systems

📦 What is this software?
Iview by Advantech
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attacker to execute arbitrary code with local service privileges, potentially leading to lateral movement, data exfiltration, or disruption of industrial control systems.
Likely Case
Database compromise through SQL injection, potentially leading to data theft, manipulation, or denial of service affecting iView functionality.
If Mitigated
Limited impact if proper network segmentation, least privilege access, and input validation are implemented, though SQL injection could still expose sensitive data.
🎯 Exploit Status
Exploitation requires authenticated access but SQL injection to RCE chain is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://www.advantech.com/en/support/details/firmware-?id=1-HIPU-183
Restart Required: Yes
Instructions:
1. Review vendor advisory at provided URL. 2. Download and apply the recommended patch/update. 3. Restart the iView service or system as required. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allIsolate iView systems from untrusted networks and implement strict firewall rules to limit access to authorized users only.
Access Control
allImplement principle of least privilege by restricting user accounts to only necessary functions and regularly reviewing access permissions.
🧯 If You Can't Patch
- Implement web application firewall (WAF) with SQL injection protection rules
- Monitor and audit all access to iView systems, particularly focusing on SQL query patterns and unusual authentication attempts
🔍 How to Verify
Check if Vulnerable:
Check iView version against vendor advisory; examine if NetworkServlet.archiveTrapRange() endpoint accepts unsanitized input parameters.Check Version:
Check iView administration interface or configuration files for version information (specific command depends on installation)Verify Fix Applied:
Verify iView version matches patched version from vendor advisory; test that SQL injection attempts against archiveTrapRange() endpoint are properly blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed authentication attempts followed by successful login
- Unexpected process execution by local service account
Network Indicators:
- Unusual traffic patterns to iView web interface
- SQL injection patterns in HTTP requests to archiveTrapRange endpoint
SIEM Query:
source="iView_logs" AND (event="SQL_error" OR event="unusual_query" OR user="*" AND action="archiveTrapRange" AND parameters="*sql*" )
