CVE-2025-14521
📋 TL;DR
This CVE describes a path traversal vulnerability in baowzh hfly's admin interface that allows attackers to read arbitrary files on the server. The vulnerability exists in the /admin/index.php/datafile/download endpoint where the filename parameter can be manipulated to access files outside the intended directory. This affects all deployments of baowzh hfly up to commit 638ff9abe9078bc977c132b37acbe1900b63491c.

Hfly by Baowzh
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive system files like /etc/passwd, configuration files containing credentials, or application source code, potentially leading to full system compromise.
Likely Case
Unauthorized reading of sensitive application files, configuration data, or user information stored on the server.
If Mitigated
Limited impact with proper file permissions and web server configuration restricting access to sensitive directories.
🎯 Exploit Status
Public exploit details are available in GitHub repositories. The vulnerability requires no authentication and uses simple path traversal techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - vendor did not respond
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider applying community fixes or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to the filename parameter to prevent directory traversal sequences
Modify /admin/index.php/datafile/download to validate filename parameter against allowed patterns
Web Server Access Restrictions
allConfigure web server to restrict access to sensitive directories
Add appropriate .htaccess rules or nginx location blocks to limit file access
🧯 If You Can't Patch
- Implement WAF rules to block path traversal patterns in requests
- Restrict network access to the admin interface using firewall rules
🔍 How to Verify
Check if Vulnerable:
Test if you can access /admin/index.php/datafile/download?filename=../../../etc/passwd (or similar traversal patterns)Check Version:
Check git commit hash: git log --oneline -1Verify Fix Applied:
Attempt the same traversal attack after implementing fixes; should return error or empty response📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /admin/index.php/datafile/download with ../ patterns in parameters
- Unusual file access patterns from single IPs
Network Indicators:
- HTTP requests containing directory traversal sequences (../, ..\, etc.)
SIEM Query:
web.url:*datafile/download* AND (web.param.filename:*../* OR web.param.filename:*..\*)
