CVE-2025-1960
📋 TL;DR
This vulnerability allows attackers to execute unauthorized commands on Schneider Electric systems when default credentials remain unchanged after installation. The WebHMI interface incorrectly displays the default username, making it harder for administrators to identify and change insecure defaults. Organizations using affected Schneider Electric products with unchanged default passwords are at risk.
💻 Affected Systems
- Schneider Electric WebHMI products (specific models not detailed in provided reference)
⚠️ Manual Verification Required

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary commands, disrupt industrial operations, steal sensitive data, or pivot to other network systems.
Likely Case
Unauthorized access to the WebHMI interface leading to configuration changes, data exfiltration, or disruption of monitoring/control functions.
If Mitigated
Minimal impact if default credentials were changed during initial setup and proper network segmentation is in place.
🎯 Exploit Status
Exploitation requires knowledge of default credentials and network access to the WebHMI interface. The vulnerability is simple to exploit once the target is identified.

Restart Required: Yes
Instructions:
1. Download the security patch from Schneider Electric's website. 2. Apply the patch according to vendor instructions. 3. Restart the system as required. 4. Verify the fix by checking that default credentials no longer work.
🔧 Temporary Workarounds
Change Default Credentials
allImmediately change all default passwords and usernames on affected systems
Use WebHMI interface to change administrator credentials
Network Segmentation
allIsolate WebHMI systems from untrusted networks and implement firewall rules
Configure firewall to restrict access to WebHMI ports (typically HTTP/HTTPS)
🧯 If You Can't Patch
- Immediately change all default credentials to strong, unique passwords
- Implement network segmentation and firewall rules to restrict access to WebHMI interfaces
🔍 How to Verify
Check if Vulnerable:
Attempt to log into WebHMI interface using default credentials. Check if default username/password combinations still work.Check Version:
Check WebHMI interface system information page or consult vendor documentationVerify Fix Applied:
Verify that default credentials no longer provide access. Confirm system is running patched version.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts followed by successful login
- Login events using default usernames
