CVE-2026-24455
📋 TL;DR
This vulnerability exposes user credentials through unencrypted HTTP Basic Authentication in an embedded web interface. Attackers on the same network can passively intercept authentication traffic. This affects devices with the vulnerable web interface exposed on the network.

⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the device, potentially compromising the entire system or network segment.
Likely Case
Attackers capture legitimate user credentials and use them for unauthorized access to the device.
If Mitigated
Limited exposure with network segmentation and monitoring detecting credential capture attempts.
🎯 Exploit Status
Exploitation requires network traffic interception capabilities but no authentication to the device.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-26-050-03
Restart Required: No
Instructions:
1. Check vendor advisory for specific device updates. 2. If TLS/HTTPS support is available, enable it. 3. Configure web interface to require HTTPS only.
🔧 Temporary Workarounds
Network Segmentation
allIsolate vulnerable devices to separate VLANs with strict access controls
Reverse Proxy with TLS
linuxPlace device behind reverse proxy that adds TLS encryption
# Example nginx config:
server {
listen 443 ssl;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
location / {
proxy_pass http://device-ip:port;
proxy_set_header Host $host;
}
}
🧯 If You Can't Patch
- Implement network segmentation to limit exposure
- Deploy network monitoring to detect credential interception attempts
🔍 How to Verify
Check if Vulnerable:
1. Access device web interface via HTTP (not HTTPS). 2. Check if authentication uses Basic Auth without TLS. 3. Use network sniffer to confirm credentials are transmitted in cleartext.Check Version:
Device-specific - check web interface or console for firmware versionVerify Fix Applied:
1. Confirm web interface requires HTTPS. 2. Verify TLS certificate is valid. 3. Test that HTTP requests redirect to HTTPS or are blocked.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from unusual IPs
- Successful logins from unexpected network segments
Network Indicators:
- Unencrypted HTTP traffic containing Authorization: Basic headers
- Network sniffing tools detected on same segment
SIEM Query:
source="network_traffic" AND http.method="POST" AND http.url CONTAINS "/login" AND NOT tls.version EXISTS
