CVE-2025-60739
📋 TL;DR
A Cross-Site Request Forgery (CSRF) vulnerability in Ilevia EVE X1 Server firmware allows remote attackers to execute arbitrary code via the /bh_web_backend component. This affects Ilevia EVE X1 Server firmware versions v4.7.18.0.eden and earlier with Logic Version v6.00 - 2025_07_21. Attackers can trick authenticated users into performing unintended actions that lead to code execution.
💻 Affected Systems
- Ilevia EVE X1 Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote unauthenticated attacker gains full system control, installs persistent malware, pivots to internal networks, and exfiltrates sensitive data.
Likely Case
Attacker executes arbitrary commands on the server, potentially compromising the device and any connected systems or data.
If Mitigated
Attack fails due to CSRF protections, proper network segmentation, or lack of authenticated user interaction.
🎯 Exploit Status
Exploit requires social engineering to trick an authenticated user, but the technical execution is straightforward once the user interacts with malicious content.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
Check vendor website for firmware updates. If available, download and apply the latest firmware version following vendor instructions.
🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd anti-CSRF tokens to all state-changing requests in the web interface.
Restrict Network Access
linuxLimit access to the web interface to trusted IP addresses only.
iptables -A INPUT -p tcp --dport 80 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Isolate the device on a separate VLAN with strict firewall rules blocking all unnecessary inbound/outbound traffic.
- Disable the web interface if not required and use alternative management methods.
🔍 How to Verify
Check if Vulnerable:
Check firmware version in web interface or via SSH: grep -i version /etc/version or similar vendor-specific command.Check Version:
Check web interface admin panel or vendor-specific CLI command (exact command unknown).Verify Fix Applied:
Verify firmware version is newer than v4.7.18.0.eden and test CSRF protection by attempting to submit a form without valid tokens.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /bh_web_backend from unexpected sources
- Multiple failed authentication attempts followed by successful CSRF exploitation
Network Indicators:
- HTTP requests to /bh_web_backend with suspicious parameters from external IPs
- Outbound connections from the device to unknown IPs post-exploit
