CVE-2025-41229
📋 TL;DR
VMware Cloud Foundation contains a directory traversal vulnerability (CWE-22) that allows attackers with network access to port 443 to access internal services. This affects organizations running vulnerable versions of VMware Cloud Foundation, potentially exposing sensitive internal systems to unauthorized access.
💻 Affected Systems
- VMware Cloud Foundation
⚠️ 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).

- Review the CVE details at 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
Attackers could access sensitive internal services, potentially leading to data exfiltration, lateral movement within the network, or complete system compromise.
Likely Case
Unauthorized access to internal services, potentially exposing configuration data, logs, or other sensitive information that could facilitate further attacks.
If Mitigated
Limited impact due to network segmentation, proper access controls, and monitoring that would detect and block traversal attempts.
🎯 Exploit Status
Directory traversal vulnerabilities typically have low exploitation complexity once the vulnerability is understood
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/25733
Restart Required: Yes
Instructions:
1. Review the vendor advisory for affected versions. 2. Apply the recommended patches from VMware. 3. Restart affected services as required. 4. Verify the fix is applied correctly.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to port 443 on VMware Cloud Foundation to only trusted sources
Web Application Firewall
allImplement WAF rules to block directory traversal patterns
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach port 443 on affected systems
- Deploy additional monitoring and alerting for suspicious access patterns to internal services
🔍 How to Verify
Check if Vulnerable:
Check VMware Cloud Foundation version against vendor advisory for affected versionsCheck Version:
Check VMware Cloud Foundation management interface or use VMware-specific CLI tools for version informationVerify Fix Applied:
Verify that the patched version is installed and running, and test that directory traversal attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to internal services
- HTTP requests containing directory traversal sequences (../, ..\)
- Failed authentication attempts followed by traversal attempts
Network Indicators:
- Unusual traffic patterns to port 443
- Requests containing directory traversal patterns in HTTP headers or parameters
