CVE-2024-45693
📋 TL;DR
Apache CloudStack has a Cross-Site Request Forgery (CSRF) vulnerability that allows attackers to trick authenticated users into performing unauthorized actions. This can lead to privilege escalation, account takeover, data exposure, and resource compromise. Affected versions are 4.15.1.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1.
💻 Affected Systems
- Apache CloudStack
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover leading to full administrative control over CloudStack resources, data exfiltration, and disruption of cloud infrastructure.
Likely Case
Unauthorized actions performed by authenticated users, potentially leading to privilege escalation and access to sensitive resources.
If Mitigated
Limited impact with proper CSRF protections and network segmentation in place.
🎯 Exploit Status
Exploitation requires tricking an authenticated user into visiting a malicious page; no authentication bypass needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.18.2.4 or 4.19.1.2 or later
Vendor Advisory: https://cloudstack.apache.org/blog/security-release-advisory-4.18.2.4-4.19.1.2
Restart Required: Yes
Instructions:
1. Backup your CloudStack configuration and database. 2. Download the patched version from Apache CloudStack website. 3. Follow the official upgrade guide for your version. 4. Restart CloudStack management server and affected services.
🔧 Temporary Workarounds
Implement CSRF Tokens Manually
allAdd CSRF protection headers or tokens to CloudStack web interface requests
Requires custom web application firewall rules or proxy configuration
Network Segmentation
linuxRestrict access to CloudStack management interface to trusted networks only
iptables -A INPUT -p tcp --dport 8080 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit CloudStack management interface exposure
- Deploy a web application firewall with CSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check CloudStack version via management server UI or API; versions 4.15.1.0-4.18.2.3 or 4.19.0.0-4.19.1.1 are vulnerable.Check Version:
cat /etc/cloudstack/management/version.properties | grep versionVerify Fix Applied:
Verify version is 4.18.2.4+ or 4.19.1.2+ and test CSRF protection mechanisms.📡 Detection & Monitoring
Log Indicators:
- Unexpected administrative actions from user accounts
- Requests missing CSRF tokens or with suspicious referrers
Network Indicators:
- HTTP requests to CloudStack management interface with external referrers
- Multiple failed CSRF validation attempts
SIEM Query:
source="cloudstack.log" AND ("CSRF validation failed" OR "invalid token")
