CVE-2024-33620
📋 TL;DR
An absolute path traversal vulnerability in ID Link Manager and FUJITSU Software TIME CREATOR allows unauthenticated remote attackers to read arbitrary files on the server, potentially exposing sensitive information. This affects organizations using these specific Fujitsu software products with vulnerable versions exposed to network access.
💻 Affected Systems
- ID Link Manager
- FUJITSU Software TIME CREATOR
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete server file system compromise including sensitive configuration files, credentials, and proprietary data exfiltration
Likely Case
Unauthorized access to configuration files, logs, and potentially sensitive application data stored on the server
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to vulnerable services
🎯 Exploit Status
Path traversal vulnerabilities typically have low exploitation complexity, especially with unauthenticated access
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Patched versions available per vendor advisory
Vendor Advisory: https://www.fujitsu.com/jp/group/fsas/about/resources/security/2024/0617.html
Restart Required: Yes
Instructions:
1. Download latest patches from Fujitsu support portal 2. Apply patches to affected systems 3. Restart services 4. Verify patch application
🔧 Temporary Workarounds
Network Access Restriction
windowsRestrict network access to vulnerable services using firewall rules
Windows Firewall: New-NetFirewallRule -DisplayName "Block IDLinkManager" -Direction Inbound -Protocol TCP -LocalPort <service_port> -Action Block
Service Disablement
windowsTemporarily disable vulnerable services if not critically required
sc stop "IDLinkManagerService"
sc config "IDLinkManagerService" start= disabled
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems from untrusted networks
- Deploy web application firewall (WAF) with path traversal protection rules
🔍 How to Verify
Check if Vulnerable:
Check if ID Link Manager or TIME CREATOR services are running and accessible on network portsCheck Version:
Check application version in Control Panel > Programs and Features or via vendor-specific version check toolsVerify Fix Applied:
Verify service version matches patched version from vendor advisory and test path traversal attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns in application logs
- Multiple failed path traversal attempts
- Access to sensitive file paths from unauthorized sources
Network Indicators:
- HTTP requests containing '../' sequences or absolute paths
- Unusual outbound data transfers following file access attempts
