CVE-2024-45479
📋 TL;DR
This CVE describes a Server-Side Request Forgery (SSRF) vulnerability in the Edit Service Page of Apache Ranger UI. Attackers can exploit this to make unauthorized requests from the Ranger server to internal or external systems, potentially accessing sensitive data or services. Organizations running Apache Ranger 2.4.0 are affected.
💻 Affected Systems
- Apache Ranger
📦 What is this software?
Ranger by Apache
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of internal network resources, data exfiltration from cloud metadata services, or lateral movement to other systems via the Ranger server's network position.
Likely Case
Unauthorized access to internal HTTP services, scanning of internal networks, or retrieval of cloud instance metadata containing credentials.
If Mitigated
Limited impact if network segmentation restricts Ranger server's outbound connections and internal services require authentication.
🎯 Exploit Status
Exploitation requires authenticated access to the Ranger UI with permissions to edit services. The vulnerability is in a web interface, making exploitation straightforward for authenticated attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apache Ranger 2.5.0
Vendor Advisory: https://cwiki.apache.org/confluence/display/RANGER/Vulnerabilities+found+in+Ranger
Restart Required: Yes
Instructions:
1. Download Apache Ranger 2.5.0 from official Apache repositories. 2. Backup current Ranger configuration and data. 3. Stop Ranger services. 4. Install version 2.5.0 following Apache documentation. 5. Restore configuration if needed. 6. Start Ranger services. 7. Verify functionality.
🔧 Temporary Workarounds
Network Restriction
linuxRestrict outbound network connections from the Ranger server to only necessary destinations using firewall rules.
# Example iptables rule to restrict outbound HTTP/HTTPS
# iptables -A OUTPUT -p tcp --dport 80 -j DROP
# iptables -A OUTPUT -p tcp --dport 443 -j DROP
Access Control
allLimit access to the Ranger UI Edit Service Page to only authorized administrators using RBAC or network ACLs.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the Ranger server from sensitive internal systems.
- Monitor and alert on unusual outbound HTTP requests from the Ranger server to detect exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check Apache Ranger version via admin UI or configuration files. If version is 2.4.0, the system is vulnerable.Check Version:
grep 'ranger.version' /path/to/ranger/install/conf/ranger-admin-site.xml or check Ranger UI admin dashboardVerify Fix Applied:
After upgrading, confirm version is 2.5.0 or higher and test that the Edit Service Page no longer allows SSRF requests to arbitrary URLs.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests originating from Ranger server to internal/external systems
- Multiple failed authentication attempts followed by Edit Service Page access
Network Indicators:
- HTTP requests from Ranger server to unexpected destinations (cloud metadata services, internal APIs)
- Outbound connections to non-standard ports from Ranger server
SIEM Query:
source="ranger-server" AND (http_request OR outbound_connection) AND destination_ip NOT IN [allowed_destinations]
