CVE-2022-22354
📋 TL;DR
This vulnerability allows attackers to perform Slowloris HTTP denial-of-service attacks against IBM Spectrum Protect Plus and IBM Spectrum Copy Data Management. By keeping HTTP connections open without completing requests, attackers can exhaust server resources and make the Admin Console unresponsive. Affected organizations are those running vulnerable versions of these IBM data management products.
💻 Affected Systems
- IBM Spectrum Protect Plus
- IBM Spectrum Copy Data Management
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete unavailability of the Admin Console, preventing administrators from managing backup and data protection operations, potentially disrupting critical data protection workflows.
Likely Case
Intermittent Admin Console unresponsiveness during attack periods, degrading administrative capabilities and potentially affecting backup scheduling and monitoring.
If Mitigated
Minimal impact with proper network segmentation, rate limiting, and updated versions, though some performance degradation might still occur during attacks.
🎯 Exploit Status
Slowloris attacks are well-known and require minimal technical skill to execute. No authentication is required to exploit this vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: IBM Spectrum Protect Plus 10.1.10 and later; IBM Spectrum Copy Data Management 2.2.15 and later
Vendor Advisory: https://www.ibm.com/support/pages/node/6562479
Restart Required: Yes
Instructions:
1. Download the latest version from IBM Fix Central. 2. Backup current configuration. 3. Apply the update following IBM's installation guide. 4. Restart the services. 5. Verify the Admin Console is functioning.
🔧 Temporary Workarounds
Implement Web Application Firewall (WAF)
allConfigure WAF rules to detect and block Slowloris attack patterns by limiting connection duration and request rates.
Network Segmentation and Access Control
allRestrict access to the Admin Console to trusted networks only, reducing the attack surface.
🧯 If You Can't Patch
- Implement network-based rate limiting to restrict the number of concurrent connections from single IP addresses.
- Deploy reverse proxy with connection timeout settings to terminate idle connections before they exhaust server resources.
🔍 How to Verify
Check if Vulnerable:
Check the product version via Admin Console or command line. If running IBM Spectrum Protect Plus 10.1.0.0-10.1.9.2 or IBM Spectrum Copy Data Management 2.2.0.0-2.2.14.3, the system is vulnerable.Check Version:
For IBM Spectrum Protect Plus: Check via Admin Console → Help → About. For command line: varies by platform (consult product documentation).Verify Fix Applied:
After patching, verify the version is IBM Spectrum Protect Plus 10.1.10+ or IBM Spectrum Copy Data Management 2.2.15+. Test the Admin Console under simulated load to ensure responsiveness.📡 Detection & Monitoring
Log Indicators:
- Unusually high number of concurrent HTTP connections
- Long-duration incomplete HTTP requests
- Admin Console access logs showing repeated connection attempts from single IPs
Network Indicators:
- Multiple partial HTTP requests from same source IP
- Sustained TCP connections without completing HTTP transactions
- Abnormal traffic patterns to Admin Console port
SIEM Query:
