⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface the website, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers inject malicious scripts that steal session cookies or credentials when administrators view the payment configuration page, leading to unauthorized access.
If Mitigated
With proper input validation and output encoding, the scripts would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Exploitation requires access to the payment configuration interface, typically requiring authentication.

🔍 How to Verify
Check if Vulnerable:
Test if script tags can be injected into id or name parameters of /configuracao/meio_pagamento.php and persist when page is reloadedCheck Version:
Check WeGIA version in configuration files or admin interfaceVerify Fix Applied:
Attempt to inject test payloads like <script>alert('XSS')</script> and verify they are properly sanitized or blocked📡 Detection & Monitoring
Log Indicators:
