CVE-2026-1632

9.1 CRITICAL

📋 TL;DR

MOMA Seismic Station versions v2.4.2520 and earlier expose their web management interface without requiring authentication. This allows unauthenticated attackers to modify device configurations, access sensitive data, or perform remote resets. Organizations using these vulnerable seismic monitoring devices are affected.

💻 Affected Systems

Products:
  • MOMA Seismic Station
Versions: v2.4.2520 and prior
Operating Systems: Embedded/Proprietary
Default Config Vulnerable: ⚠️ Yes
Notes: All installations with default configuration are vulnerable. The web management interface is accessible without authentication by default.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

An attacker could reconfigure seismic monitoring parameters to suppress alerts, access sensitive geological data, or disable the device entirely, potentially compromising safety monitoring systems.

🟠

Likely Case

Unauthenticated attackers accessing the web interface to view device data, modify basic settings, or perform device resets disrupting monitoring operations.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to internal network compromise rather than direct device manipulation.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires only web browser access to the management interface. No special tools or techniques needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v2.4.2521 or later

Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-26-034-03

Restart Required: Yes

Instructions:

1. Download updated firmware from vendor. 2. Backup current configuration. 3. Apply firmware update via web interface. 4. Verify authentication is now required. 5. Restart device.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate MOMA Seismic Station devices on separate VLAN with strict firewall rules

Access Control Lists

linux

Implement IP-based restrictions to only allow authorized management stations

# Example firewall rule (adjust for your environment)
iptables -A INPUT -p tcp --dport 80 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate devices from untrusted networks
  • Deploy network-based authentication proxy in front of the web interface

🔍 How to Verify

Check if Vulnerable:

Attempt to access the web management interface (typically port 80/443) without credentials. If you can access configuration pages without login, the device is vulnerable.

Check Version:

Check web interface footer or about page, or use: curl -s http://device-ip/ | grep -i version

Verify Fix Applied:

After patching, attempt to access web interface without credentials. You should be redirected to a login page or receive authentication error.

📡 Detection & Monitoring

Log Indicators:

  • Unauthenticated access to admin pages
  • Configuration changes from unexpected IPs
  • Multiple failed login attempts followed by successful access

Network Indicators:

  • HTTP requests to /admin, /config, or /settings paths without authentication headers
  • Traffic to seismic station on port 80/443 from unexpected sources

SIEM Query:

source="moma_logs" AND (url_path="/admin" OR url_path="/config" OR url_path="/settings") AND NOT (http_auth="*" OR cookie="session*")
