CVE-2025-10713
📋 TL;DR
An XML External Entity (XXE) vulnerability in multiple WSO2 products allows attackers to read sensitive server files or cause denial-of-service. The vulnerability affects unauthenticated remote attackers who can submit XML to vulnerable endpoints. This impacts organizations using affected WSO2 products with default or insufficient XML parser configurations.
💻 Affected Systems
- WSO2 API Manager
- WSO2 Identity Server
- WSO2 Enterprise Integrator
- WSO2 Micro Integrator
- WSO2 Streaming Integrator
- WSO2 Open Banking
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through sensitive file disclosure (e.g., configuration files, credentials, private keys) leading to data breach and potential lateral movement.
Likely Case
Unauthorized reading of server files containing configuration data, credentials, or other sensitive information, potentially enabling further attacks.
If Mitigated
Limited impact with proper network segmentation, input validation, and XML parser hardening, though some risk remains until patched.
🎯 Exploit Status
XXE vulnerabilities are well-understood with established exploitation techniques. While no public PoC exists for this specific CVE, XXE exploitation is generally straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check WSO2 security advisory WSO2-2025-4505 for specific patched versions per product
Vendor Advisory: https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2025/WSO2-2025-4505/
Restart Required: Yes
Instructions:
1. Review WSO2 advisory WSO2-2025-4505 for affected versions. 2. Apply the security patch provided by WSO2. 3. Restart the WSO2 server. 4. Verify the fix by testing XXE payloads.
🔧 Temporary Workarounds
Disable XXE in XML parser
allConfigure XML parser to disable external entity resolution
Modify XML parser configuration in WSO2 to set: FEATURE_SECURE_PROCESSING = true, DISALLOW_DOCTYPE_DECL = true
Input validation and filtering
allImplement XML input validation to reject malicious payloads
Implement XML schema validation or regex filtering for user-supplied XML
🧯 If You Can't Patch
- Implement network-level controls to restrict XML input to trusted sources only
- Deploy WAF with XXE protection rules and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Test with XXE payloads: Submit XML containing external entity references to WSO2 endpoints and check for file disclosure or error responses.Check Version:
Check WSO2 product version via management console or server logsVerify Fix Applied:
After patching, resubmit XXE test payloads and verify they are rejected or processed safely without external entity resolution.📡 Detection & Monitoring
Log Indicators:
- Unusual XML parsing errors
- File access attempts via XML parsing
- Large XML payloads causing DoS
Network Indicators:
- XML payloads containing external entity references (SYSTEM, PUBLIC declarations)
- Unusual outbound connections from WSO2 servers
SIEM Query:
