CVE-2023-36651
📋 TL;DR
CVE-2023-36651 is a critical authentication bypass vulnerability in ProLion CryptoSpike 3.0.15P2 where hard-coded super-admin credentials allow remote attackers to gain full administrative access to the web management interface and REST API. This affects all organizations running the vulnerable version of CryptoSpike, a data security platform for storage systems. Attackers can completely compromise the system's security controls and access sensitive data.
💻 Affected Systems
- ProLion CryptoSpike
📦 What is this software?
Cryptospike by Prolion
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover allowing attackers to disable security controls, exfiltrate all protected data, manipulate encryption settings, and use the compromised system as a foothold into connected storage infrastructure.
Likely Case
Unauthorized administrative access leading to data theft, configuration changes, and potential ransomware deployment on protected storage systems.
If Mitigated
Limited impact if network segmentation prevents external access and internal monitoring detects unusual administrative activity.
🎯 Exploit Status
Exploitation requires only knowledge of the hard-coded credentials and network access to the management interface. No special tools or skills needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 3.0.15P2
Vendor Advisory: https://www.cvcn.gov.it/cvcn/cve/CVE-2023-36651
Restart Required: Yes
Instructions:
1. Contact ProLion support for updated version. 2. Backup current configuration. 3. Apply vendor-provided patch/upgrade. 4. Restart CryptoSpike services. 5. Verify new credentials are required for admin access.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict access to CryptoSpike management interface to only trusted administrative networks
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_IP" port protocol="tcp" port="443" accept'
firewall-cmd --reload
IP Whitelisting
linuxConfigure web server to only allow connections from authorized administrative IP addresses
iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Immediately change all passwords and API keys stored in CryptoSpike as they may have been compromised
- Implement strict network segmentation to isolate CryptoSpike from internet and non-administrative networks
🔍 How to Verify
Check if Vulnerable:
Check CryptoSpike version via web interface or CLI. If version is 3.0.15P2, system is vulnerable.Check Version:
Check web interface footer or run: cat /opt/cryptospike/version.txtVerify Fix Applied:
Attempt to login with default/hard-coded credentials - should fail. Verify version is greater than 3.0.15P2.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts followed by successful login from unusual IP
- Administrative actions from non-standard user accounts or IPs
- REST API calls with super-admin privileges from unexpected sources
Network Indicators:
- HTTP POST requests to /api/login endpoint from unauthorized networks
- Unusual volume of API calls to privileged endpoints
- Connections to management interface from non-administrative subnets
SIEM Query:
source="cryptospike" (event_type="login_success" AND user="admin") OR (http_method="POST" AND uri_path="/api/*" AND src_ip NOT IN [admin_networks])
