CVE-2025-15225

7.5 HIGH

📋 TL;DR

WMPro software developed by Sunnet contains an arbitrary file read vulnerability due to relative path traversal. Unauthenticated remote attackers can exploit this to read sensitive system files. Organizations using WMPro are affected.

💻 Affected Systems

Products:
  • WMPro
Versions: Specific versions not specified in references; assume all versions until patched
Operating Systems: Windows, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Vulnerability exists in default configuration; no special configuration required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could read sensitive system files like /etc/passwd, /etc/shadow, configuration files, or database credentials, leading to full system compromise.

🟠

Likely Case

Attackers will read configuration files, logs, or other sensitive data to gather information for further attacks.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to the WMPro application server only.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires simple HTTP requests with path traversal sequences; no authentication needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not specified

Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10603-67149-2.html

Restart Required: No

Instructions:

1. Monitor vendor website for security updates. 2. Apply patch when available. 3. Test in non-production environment first.

🔧 Temporary Workarounds

Network Access Control

all

Restrict network access to WMPro to trusted IPs only

Web Application Firewall

all

Deploy WAF with path traversal protection rules

🧯 If You Can't Patch

  • Isolate WMPro server in separate network segment
  • Implement strict file system permissions on sensitive directories

🔍 How to Verify

Check if Vulnerable:

Test with HTTP request containing path traversal sequences (e.g., GET /../../etc/passwd) to WMPro endpoint

Check Version:

Check WMPro version in web interface or configuration files

Verify Fix Applied:

Retest with same path traversal requests after applying controls; should return error or be blocked

📡 Detection & Monitoring

Log Indicators:

  • HTTP requests containing ../ sequences
  • Access to unusual file paths in web logs
  • Failed file read attempts

Network Indicators:

  • Unusual file read patterns from external IPs
  • Multiple ../ sequences in HTTP requests

SIEM Query:

source="wmpro_logs" AND (uri="*../*" OR status=200 AND uri="*/etc/*" OR uri="*/windows/*")
