CVE-2019-9047
📋 TL;DR
CVE-2019-9047 is a SQL injection vulnerability in GoRose ORM v1.0.4 that allows attackers to execute arbitrary SQL commands when they can control order_by or group_by parameters. This affects any application using the vulnerable GoRose library version. Attackers can potentially read, modify, or delete database contents.

Gorose by Fizzday
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, or deletion; potential remote code execution if database functions allow it.
Likely Case
Data extraction from database, authentication bypass, or privilege escalation through SQL injection.
If Mitigated
Limited impact with proper input validation and parameterized queries in place.
🎯 Exploit Status
SQL injection is well-understood with many automated tools available; public PoC exists in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.0.5 and later
Vendor Advisory: https://github.com/gohouse/gorose
Restart Required: No
Instructions:
1. Update GoRose dependency to v1.0.5 or later. 2. Run 'go get -u github.com/gohouse/gorose'. 3. Rebuild and redeploy application.
🔧 Temporary Workarounds
Input validation and sanitization
allImplement strict input validation for order_by and group_by parameters before passing to GoRose.
Use parameterized queries
allAvoid passing user input directly to order_by/group_by; use whitelisted values or parameterized approaches.
🧯 If You Can't Patch
- Implement WAF rules to block SQL injection patterns in order_by/group_by parameters
- Restrict database user permissions to minimum required for application functionality
🔍 How to Verify
Check if Vulnerable:
Check go.mod or vendor dependencies for gorose v1.0.4; review code for user input in order_by/group_by parameters.Check Version:
grep gorose go.mod || find vendor/ -name "*.go" -exec grep -l "gorose" {} \; | head -5Verify Fix Applied:
Confirm gorose version is v1.0.5+ in go.mod; test with SQL injection payloads in order_by/group_by parameters.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries with UNION, SELECT, or database functions in order/group clauses
- Multiple failed login attempts followed by order_by parameter manipulation
Network Indicators:
- HTTP requests with SQL keywords in order_by or group_by parameters
- Abnormal database query patterns from application servers
SIEM Query:
web_requests WHERE (uri_query CONTAINS 'order_by' OR uri_query CONTAINS 'group_by') AND (uri_query CONTAINS 'UNION' OR uri_query CONTAINS 'SELECT' OR uri_query CONTAINS '--')
