CVE-2025-13510
📋 TL;DR
The Iskra iHUB and iHUB Lite smart metering gateways expose their web management interfaces without requiring any authentication. This allows unauthenticated attackers to access and modify critical device settings, potentially disrupting metering operations. Organizations using these devices in smart grid infrastructure are affected.
💻 Affected Systems
- Iskra iHUB
- Iskra iHUB Lite
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could reconfigure or disable the gateway, manipulate metering data, disrupt utility services, or use the device as an entry point to attack the broader smart grid network.
Likely Case
Unauthorized users accessing device settings, changing configurations, or causing service interruptions to connected meters.
If Mitigated
Limited to network reconnaissance if proper network segmentation and access controls are implemented.
🎯 Exploit Status
Direct web interface access requires no authentication, making exploitation trivial for anyone with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check with Iskra for specific firmware versions
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-25-336-02
Restart Required: Yes
Instructions:
1. Contact Iskra for updated firmware. 2. Backup current configuration. 3. Apply firmware update via web interface or management tool. 4. Verify authentication is now required. 5. Restart device if required by update.
🔧 Temporary Workarounds
Network Segmentation
allIsolate iHUB devices in dedicated network segments with strict firewall rules
Access Control Lists
allImplement network ACLs to restrict access to iHUB management interfaces
🧯 If You Can't Patch
- Implement strict network segmentation to isolate iHUB devices from untrusted networks
- Deploy network monitoring and intrusion detection specifically for iHUB management interface traffic
🔍 How to Verify
Check if Vulnerable:
Attempt to access the iHUB web management interface (typically port 80/443) without credentials. If access is granted, device is vulnerable.Check Version:
Check firmware version via web interface or device management consoleVerify Fix Applied:
After patching, attempt to access web interface without credentials - should receive authentication prompt or be denied access.📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to management URLs
- Configuration changes from unknown IPs
- Multiple failed login attempts if authentication is enabled
Network Indicators:
- HTTP requests to iHUB management interface without authentication headers
- Traffic from unexpected sources to iHUB management ports
SIEM Query:
source_ip=* AND dest_port IN (80,443) AND dest_ip=iHUB_IP AND http_user_agent NOT CONTAINS 'authenticated'
