CVE-2025-6445
📋 TL;DR
ServiceStack's FindType method contains a directory traversal vulnerability that allows remote attackers to execute arbitrary code by manipulating file paths. This affects applications using vulnerable ServiceStack versions that expose the FindType functionality. Attackers can achieve remote code execution in the context of the application process.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via remote code execution with application privileges, potentially leading to data theft, lateral movement, or ransomware deployment.
Likely Case
Remote code execution allowing attackers to steal sensitive data, deploy malware, or pivot to other systems within the network.
If Mitigated
Limited impact due to proper input validation, network segmentation, and least privilege controls preventing successful exploitation.
🎯 Exploit Status
Exploitation requires interaction with the vulnerable library but attack vectors vary by implementation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.0.6
Vendor Advisory: https://docs.servicestack.net/releases/v8_06#reported-vulnerabilities
Restart Required: Yes
Instructions:
1. Update ServiceStack to version 8.0.6 or later. 2. Restart the application. 3. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation
allImplement strict input validation for all user-supplied paths used with FindType method.
Network Segmentation
allRestrict network access to vulnerable applications using firewalls or network policies.
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user-controlled path parameters
- Apply network segmentation and restrict access to vulnerable endpoints
🔍 How to Verify
Check if Vulnerable:
Check ServiceStack version in application dependencies or configuration files.Check Version:
Check package manager (nuget, npm, etc.) or application configuration for ServiceStack versionVerify Fix Applied:
Verify ServiceStack version is 8.0.6 or later and test path traversal attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual file path patterns in requests
- Failed file access attempts outside expected directories
- Suspicious process execution
Network Indicators:
- HTTP requests with directory traversal sequences (../, ..\) to ServiceStack endpoints
