CVE-2025-10907
📋 TL;DR
An arbitrary file upload vulnerability in WSO2 products allows authenticated administrators to upload malicious files to user-controlled locations via SOAP admin services. This can lead to remote code execution if the uploaded file is processed by the server. Only users with administrative access to affected SOAP services can exploit this vulnerability.
💻 Affected Systems
- WSO2 API Manager
- WSO2 Identity Server
- WSO2 Enterprise Integrator
- WSO2 Micro Integrator
- WSO2 Streaming Integrator
- WSO2 Microgateway
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Administrator with malicious intent or compromised admin credentials uploads webshell or malicious payload, gaining persistent access to the server.
If Mitigated
Limited impact due to proper access controls, file validation, and restricted admin privileges.
🎯 Exploit Status
Exploitation requires administrative credentials but is straightforward once access is obtained. The vulnerability pattern is well-known and similar to previous file upload vulnerabilities.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions per product
Vendor Advisory: https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2025/WSO2-2025-4603/
Restart Required: Yes
Instructions:
1. Review vendor advisory for specific affected versions. 2. Apply the security patch provided by WSO2. 3. Restart the affected services. 4. Verify the fix is applied correctly.
🔧 Temporary Workarounds
Restrict SOAP Admin Service Access
allLimit access to SOAP admin services to trusted IP addresses only
Configure firewall rules to restrict access to SOAP admin service ports (typically 9443)
Disable Unnecessary SOAP Services
allDisable SOAP admin services if not required for your deployment
Modify axis2.xml to disable unnecessary SOAP services
Set <parameter name="enableSOAPAdminService">false</parameter> in relevant configuration files
🧯 If You Can't Patch
- Implement strict network segmentation to isolate WSO2 instances from critical systems
- Enforce multi-factor authentication for all administrative accounts and monitor admin activity logs
🔍 How to Verify
Check if Vulnerable:
Check if your WSO2 product version matches affected versions in the vendor advisory and verify SOAP admin services are enabledCheck Version:
Check product documentation for version command specific to your WSO2 product (typically in bin directory or via management console)Verify Fix Applied:
Verify the product version has been updated to a patched version and test that file upload validation is working properly📡 Detection & Monitoring
Log Indicators:
- Unusual file upload activity via SOAP services
- Administrative user uploading unexpected file types
- Files being written to unexpected locations
Network Indicators:
- SOAP requests with file upload payloads to admin endpoints
- Unusual outbound connections from WSO2 servers after file uploads
SIEM Query:
source="wso2-logs" AND (event="FILE_UPLOAD" OR endpoint="*admin*soap*") AND (file_extension="jsp" OR file_extension="war" OR file_extension="php")
