CVE-2025-60833
📋 TL;DR
This XML External Entity (XXE) vulnerability in the uzy-ssm-mall e-commerce platform allows attackers to execute arbitrary code by sending specially crafted XML data to the /mall/wxpay/pay endpoint. It affects version 1.1.0 of the software, potentially compromising systems running this vulnerable version.
💻 Affected Systems

📦 What is this software?
Uzy Ssm Mall by Ghostxbh
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution, data exfiltration, and complete control over the affected server.
Likely Case
Server-side request forgery (SSRF), file disclosure from the server, and potential denial of service.
If Mitigated
Limited impact with proper XML parsing configuration and input validation in place.
🎯 Exploit Status
Exploitation requires sending crafted XML to the vulnerable endpoint, but no public exploit code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.1.1 or later
Vendor Advisory: https://github.com/ChangeYourWay/post/blob/main/uzy-ssm-mall.md
Restart Required: No
Instructions:
1. Update to v1.1.1 or later version of uzy-ssm-mall. 2. Replace the vulnerable XML parser with a secure configuration that disables XXE processing. 3. Validate and sanitize all XML input before processing.
🔧 Temporary Workarounds
Disable XXE in XML Parser
allConfigure the XML parser to disable external entity processing
Set XML parser properties: FEATURE_SECURE_PROCESSING = true, DISALLOW_DOCTYPE_DECL = true
Input Validation Filter
allImplement strict input validation to reject XML containing DOCTYPE declarations
Add input filter to reject requests containing '<!DOCTYPE' or '<!ENTITY' patterns
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with XXE protection rules
- Block or restrict access to the /mall/wxpay/pay endpoint
🔍 How to Verify
Check if Vulnerable:
Test by sending XML with external entity declaration to /mall/wxpay/pay endpoint and checking for file disclosure or SSRF behaviorCheck Version:
Check package.json or project configuration for version numberVerify Fix Applied:
Attempt the same XXE payload after patching; it should be rejected or processed safely without external entity resolution📡 Detection & Monitoring
