CVE-2025-62177
📋 TL;DR
A SQL injection vulnerability in WeGIA's /html/funcionario/dependente_listar.php endpoint allows attackers to execute arbitrary SQL commands via the id_funcionario parameter. This can lead to data theft, data manipulation, or complete database compromise. All WeGIA installations prior to version 3.5.1 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, data destruction, privilege escalation to system-level access, and potential lateral movement to other systems.
Likely Case
Unauthorized access to sensitive employee and dependent data, potential data modification, and possible authentication bypass to gain administrative access.
If Mitigated
Limited impact with proper input validation and WAF rules in place, potentially blocking malicious payloads before reaching the application.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited and tooling exists for automated exploitation. The advisory provides enough detail for attackers to craft working exploits.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.5.1
Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-4wrg-g9cj-hjcx
Restart Required: Yes
Instructions:
1. Backup your current WeGIA installation and database. 2. Download WeGIA version 3.5.1 from the official repository. 3. Replace the vulnerable files with the patched version. 4. Restart the web server service. 5. Verify the fix by testing the endpoint with SQL injection payloads.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the id_funcionario parameter
Input Validation Filter
allAdd server-side input validation to only accept numeric values for the id_funcionario parameter
🧯 If You Can't Patch
- Implement strict input validation to only accept numeric values for the id_funcionario parameter
- Deploy a web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test the /html/funcionario/dependente_listar.php endpoint with SQL injection payloads in the id_funcionario parameter (e.g., id_funcionario=1' OR '1'='1)Check Version:
Check the WeGIA version in the application interface or review the source code version markersVerify Fix Applied:
After patching, test the same endpoint with SQL injection payloads and verify they are rejected or properly handled📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
- Requests with SQL keywords in id_funcionario parameter
Network Indicators:
- HTTP requests containing SQL injection patterns in URL parameters
- Unusual database query patterns from the application server
SIEM Query:
source="web_logs" AND (uri_path="/html/funcionario/dependente_listar.php") AND (param="id_funcionario") AND (value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and|'|--|#|;)")
