CVE-2025-53823
📋 TL;DR
This SQL injection vulnerability in WeGIA allows attackers to execute arbitrary SQL commands through the 'id_socio' parameter in the processa_deletar_socio.php endpoint. This can lead to data theft, manipulation, or deletion of the entire database. Organizations using WeGIA versions before 3.4.5 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including exfiltration of all sensitive data, deletion of all records, and potential system takeover via SQL command execution leading to remote code execution.
Likely Case
Unauthorized access to sensitive donor, member, or financial data, with potential data manipulation or deletion affecting organizational operations.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only affecting non-critical data tables.
🎯 Exploit Status
SQL injection vulnerabilities are typically easy to exploit with basic web testing tools. The advisory suggests authentication may be required to access the endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.4.5
Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-p8xr-qg3c-6ww2
Restart Required: No
Instructions:
1. Backup your current WeGIA installation and database. 2. Download WeGIA version 3.4.5 from the official repository. 3. Replace the vulnerable file /WeGIA/html/socio/sistema/processa_deletar_socio.php with the patched version. 4. 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 vulnerable endpoint.
Endpoint Restriction
allRestrict access to the vulnerable endpoint using authentication or IP whitelisting.
🧯 If You Can't Patch
- Implement strict input validation for the 'id_socio' parameter to only accept numeric values.
- Apply database permissions to limit the impact of SQL injection (principle of least privilege).
🔍 How to Verify
Check if Vulnerable:
Test the endpoint /WeGIA/html/socio/sistema/processa_deletar_socio.php with SQL injection payloads in the 'id_socio' parameter (e.g., ' OR '1'='1).Check Version:
Check the WeGIA version in the application interface or configuration files.Verify Fix Applied:
After patching, attempt the same SQL injection tests and verify they are rejected or properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed delete attempts on socio records
- Requests with SQL keywords in parameters
Network Indicators:
- HTTP POST requests to the vulnerable endpoint with SQL payloads
- Unusual database query patterns from the application server
SIEM Query:
source="web_logs" AND uri="/WeGIA/html/socio/sistema/processa_deletar_socio.php" AND (param="id_socio" AND value CONTAINS "OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT")
