CVE-2025-8163
📋 TL;DR
This critical SQL injection vulnerability in deerwms deer-wms-2 allows remote attackers to execute arbitrary SQL commands via the params[dataScope] parameter in the /system/role/list endpoint. Attackers can potentially read, modify, or delete database contents, and in worst cases gain full system control. All users running deer-wms-2 versions up to 3.3 are affected.

Deer Wms 2 by Deerwms
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, privilege escalation to administrative access, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access and extraction, including sensitive user information, configuration data, and business records stored in the database.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions preventing data modification or system access.
🎯 Exploit Status
Exploit details have been publicly disclosed, making weaponization straightforward for attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 3.4 or later
Vendor Advisory: https://gitee.com/deerwms/deer-wms-2/issues/ICLQFL
Restart Required: Yes
Instructions:
1. Backup your current deployment and database. 2. Download the latest version from the official repository. 3. Replace the affected files with patched versions. 4. Restart the application service. 5. Verify the fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the /system/role/list endpoint and params[dataScope] parameter.
Endpoint Restriction
allRestrict access to the /system/role/list endpoint using network ACLs or authentication requirements.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all user inputs in the application code.
- Apply network segmentation to isolate the vulnerable system and restrict database access to only necessary services.
🔍 How to Verify
Check if Vulnerable:
Test the /system/role/list endpoint with SQL injection payloads in the params[dataScope] parameter and observe if database errors or unexpected responses occur.Check Version:
Check the application version in the admin interface or configuration files, or run: grep -r 'version' /path/to/deer-wms-2/ | head -5Verify Fix Applied:
Attempt the same SQL injection tests after patching; successful fixes should return proper error handling or reject malicious input without database interaction.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in request logs for /system/role/list
- Database error messages containing SQL fragments
- Multiple rapid requests to the vulnerable endpoint
Network Indicators:
- SQL keywords (SELECT, UNION, INSERT, etc.) in HTTP parameters
- Unusual database connection patterns from the application server
SIEM Query:
source="web_logs" AND uri="/system/role/list" AND (params CONTAINS "SELECT" OR params CONTAINS "UNION" OR params CONTAINS "INSERT" OR params CONTAINS "DELETE")
