CVE-2024-56471
📋 TL;DR
IBM Aspera Shares versions 1.9.0 through 1.10.0 PL6 contain a server-side request forgery (SSRF) vulnerability that allows authenticated attackers to make unauthorized requests from the server. This could enable network scanning, internal service enumeration, or facilitate other attacks. Only authenticated users can exploit this vulnerability.
💻 Affected Systems
- IBM Aspera Shares
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker could access internal services, exfiltrate sensitive data, or use the server as a pivot point for attacks against other internal systems.
Likely Case
Network enumeration of internal services, scanning for other vulnerable systems, or accessing metadata from cloud services.
If Mitigated
Limited impact if network segmentation restricts outbound connections and internal services require authentication.
🎯 Exploit Status
SSRF vulnerabilities typically have low exploitation complexity once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply IBM Aspera Shares 1.10.0 PL7 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7182490
Restart Required: Yes
Instructions:
1. Download the latest patch from IBM Fix Central. 2. Backup current configuration. 3. Apply the patch following IBM's installation guide. 4. Restart Aspera Shares services. 5. Verify the patch is applied correctly.
🔧 Temporary Workarounds
Network Restriction
allRestrict outbound network connections from Aspera Shares server to only necessary destinations
Use firewall rules to limit outbound connections to specific IPs/ports
Authentication Hardening
allImplement strong authentication controls and monitor for suspicious activity
Enable MFA, implement account lockout policies, review access logs
🧯 If You Can't Patch
- Implement strict network segmentation to limit the server's ability to reach internal systems
- Monitor for unusual outbound connections from the Aspera Shares server
🔍 How to Verify
Check if Vulnerable:
Check Aspera Shares version via web interface admin panel or configuration filesCheck Version:
Check the version in the web interface or configuration files (location varies by installation)Verify Fix Applied:
Verify version is 1.10.0 PL7 or later and test SSRF functionality is blocked📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from Aspera Shares server
- Requests to internal IP addresses or unusual domains
- Multiple failed authentication attempts followed by SSRF-like requests
Network Indicators:
- Unexpected outbound connections from Aspera Shares server to internal services
- Traffic patterns indicating port scanning from the server
