CVE-2025-65792
📋 TL;DR
DataGear v5.5.0 contains a path traversal vulnerability (CWE-22) that allows attackers to delete arbitrary files on the server. This affects all DataGear installations running version 5.5.0. Attackers can exploit this to delete critical system files, configuration files, or application data.
💻 Affected Systems
- DataGear
📦 What is this software?
Datagear by Datagear
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through deletion of critical OS files, leading to system instability, data loss, or service disruption. Attackers could delete authentication files, configuration files, or system binaries.
Likely Case
Application data loss, configuration deletion, or service disruption by deleting DataGear files, databases, or configuration files.
If Mitigated
Limited impact if proper file permissions and access controls restrict deletion to non-critical files within the application directory.
🎯 Exploit Status
Proof of concept is publicly available on GitHub. Exploitation requires some level of access to the application, but the technical complexity is low once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch is available. Check the DataGear GitHub repository for updates. Consider upgrading to a newer version if available or applying workarounds.
🔧 Temporary Workarounds
Restrict File Permissions
linuxSet strict file permissions on critical directories and files to prevent deletion
chmod 644 /path/to/datagear/config/files
chown root:root /path/to/datagear
Web Application Firewall Rules
allConfigure WAF to block path traversal patterns in requests
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataGear from critical systems
- Enable detailed logging and monitoring for file deletion operations
🔍 How to Verify
Check if Vulnerable:
Check if running DataGear version 5.5.0. Review application logs for suspicious file deletion attempts.Check Version:
Check DataGear version in application interface or configuration filesVerify Fix Applied:
Test file deletion functionality with path traversal payloads to ensure they are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual file deletion patterns
- Requests containing '../' sequences
- Failed file deletion attempts outside application directory
Network Indicators:
- HTTP requests with path traversal patterns in file deletion endpoints
