⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, credential harvesting, potential authentication bypass, and full system takeover.
Likely Case
Unauthorized access to sensitive data including user information, organizational records, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation, WAF rules, and database permissions restricting damage to specific tables.
🎯 Exploit Status
SQL injection in adicionar_raca.php endpoint requires no authentication and can be exploited with standard SQLi techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.2.10
Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-425j-h4cf-g52j
Restart Required: No
Instructions:
1. Backup your current WeGIA installation and database. 2. Download WeGIA version 3.2.10 from the official repository. 3. Replace the vulnerable adicionar_raca.php file with the patched version. 4. Verify the fix by checking the commit hash matches the security advisory.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the adicionar_raca.php endpoint.
# Example ModSecurity rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Configure WAF to block requests containing SQL keywords when targeting vulnerable endpoint
Endpoint Restriction
linuxRestrict access to the vulnerable endpoint using authentication or IP whitelisting.
# Apache: <Location "/adicionar_raca.php"> Require ip 192.168.1.0/24 </Location>
# Nginx: location = /adicionar_raca.php { allow 192.168.1.0/24; deny all; }
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all user inputs in the application.
- Deploy a web application firewall with SQL injection detection rules and monitor for exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check if WeGIA version is below 3.2.10 and if adicionar_raca.php endpoint exists without proper input sanitization.Check Version:
grep -r "version\|VERSION" /path/to/wegia/ | grep -i "3\.[0-9]\+"Verify Fix Applied:
Verify the adicionar_raca.php file hash matches the patched version in commit 1739e1589948a207b8a82b9bfe078cb826d420de.📡 Detection & Monitoring
