CVE-2025-63686
📋 TL;DR
This CVE describes an arbitrary file download vulnerability in GuoMinJim PersonManage software. Attackers can download arbitrary files from the server through the document query function in the Download Center menu. This affects all users running vulnerable versions of PersonManage.
💻 Affected Systems
- GuoMinJim PersonManage
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through downloading sensitive files like configuration files, password databases, or SSH keys, leading to lateral movement and data exfiltration.
Likely Case
Unauthorized access to sensitive personnel data, configuration files, or other business-critical information stored on the server.
If Mitigated
Limited impact if proper network segmentation, file permissions, and access controls prevent access to sensitive files.
🎯 Exploit Status
The GitHub issue shows exploitation details. Attack requires access to the PersonManage interface but no special authentication beyond normal user access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider the workarounds below or discontinue use of vulnerable versions.
🔧 Temporary Workarounds
Disable Download Center Function
allRemove or disable access to the Download Center menu and document query function
# Modify application configuration to disable Download Center functionality
# Remove or comment out Download Center menu entries in the application
Implement Web Application Firewall Rules
allBlock requests to the vulnerable endpoint patterns
# Example WAF rule to block requests to download center document query endpoints
# Block patterns like */download/*/query* or similar vulnerable paths
🧯 If You Can't Patch
- Implement strict file system permissions to limit accessible directories
- Deploy network segmentation to isolate PersonManage from sensitive systems
🔍 How to Verify
Check if Vulnerable:
Test if you can access arbitrary files through the Download Center document query function by attempting to download known system files.Check Version:
# Check PersonManage version or commit hash against vulnerable version 5a02b1ab208feacf3a34fc123c9381162afbaa95 or earlierVerify Fix Applied:
Verify that the Download Center document query function no longer allows arbitrary file downloads and only permits access to intended documents.📡 Detection & Monitoring
Log Indicators:
- Unusual file download patterns from Download Center
- Requests for system files or configuration files through document query
Network Indicators:
- Multiple download requests for non-document files
- Patterns of file path traversal attempts in URLs
SIEM Query:
source="personmanage" AND (url="*/download/*/query*" OR url CONTAINS "../") AND response_code=200
