CVE-2015-2874
📋 TL;DR
This vulnerability allows remote attackers to gain full administrative access to affected Seagate and LaCie wireless storage devices via TELNET using the default 'root' password. Anyone using these devices with vulnerable firmware is affected, potentially exposing all stored data and device control.
💻 Affected Systems
- Seagate GoFlex Satellite
- Seagate Wireless Mobile Storage
- Seagate Wireless Plus Mobile Storage
- LaCie FUEL
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing data theft, ransomware deployment, or using the device as a pivot point into internal networks.
Likely Case
Unauthorized access to stored files, data exfiltration, or device configuration changes.
If Mitigated
Limited impact if devices are isolated from untrusted networks and default credentials are changed.
🎯 Exploit Status
Exploitation requires only TELNET access and knowledge of default credentials. No special tools needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware 3.4.1.105 or later
Vendor Advisory: https://www.kb.cert.org/vuls/id/903500
Restart Required: Yes
Instructions:
1. Download latest firmware from Seagate/LaCie support site. 2. Connect device to computer via USB. 3. Run firmware updater. 4. Reboot device after update completes.
🔧 Temporary Workarounds
Disable TELNET service
allTurn off TELNET access to prevent remote exploitation
telnetd -l /bin/sh & (to check if running)
killall telnetd (to stop service)
Change root password
allSet a strong password for root account
passwd root
🧯 If You Can't Patch
- Isolate devices on separate VLAN with strict firewall rules blocking TELNET (port 23) from untrusted networks
- Implement network segmentation to prevent lateral movement if device is compromised
🔍 How to Verify
Check if Vulnerable:
Attempt TELNET connection to device on port 23 and try logging in with username 'root' and password 'root'Check Version:
Check device web interface or use 'cat /etc/version' via SSH if availableVerify Fix Applied:
After update, attempt TELNET login with default credentials should fail. Check firmware version matches 3.4.1.105 or higher.📡 Detection & Monitoring
Log Indicators:
- Failed TELNET authentication attempts
- Successful TELNET logins from unusual IPs
- Multiple TELNET connection attempts
Network Indicators:
- TELNET traffic (port 23) to storage devices
- Unusual outbound connections from storage devices
SIEM Query:
source_port=23 AND (event_type="authentication_failure" OR event_type="authentication_success") AND device_type="storage"
