CVE-2024-8884
📋 TL;DR
This CVE describes an information exposure vulnerability where credentials can be leaked when an attacker has network access to the application over HTTP. The vulnerability affects Schneider Electric products and could allow unauthorized actors to obtain sensitive authentication information. Organizations using affected Schneider Electric systems are at risk.
💻 Affected Systems
- Schneider Electric products (specific models not detailed in provided reference)
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain administrative credentials, gain full control of affected systems, and potentially pivot to other network resources.
Likely Case
Attackers capture credentials for the affected application, leading to unauthorized access and potential data exposure.
If Mitigated
With proper network segmentation and access controls, impact is limited to isolated systems with minimal sensitive data.
🎯 Exploit Status
Exploitation requires network access to vulnerable application but no authentication

HTTPS Enforcement
allConfigure application to use HTTPS only and disable HTTP
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach affected systems
- Monitor network traffic to/from affected systems for credential harvesting attempts
🔍 How to Verify
Check if Vulnerable:
Check if Schneider Electric product version matches affected versions in vendor advisoryCheck Version:
Check product-specific documentation for version query commandsVerify Fix Applied:
Verify patch version installed and test that credentials are no longer exposed over HTTP📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Multiple failed login attempts from single source
- Credential exposure in application logs
Network Indicators:
- HTTP traffic to affected application ports
- Credential harvesting patterns in network traffic
SIEM Query:
