Technical details
An information disclosure vulnerability exists in WeGIA versions prior to 3.6.10 due to improper error handling in the 'funcionario/docdependente_upload.php' component. When a user with low-level privileges attempts to upload a file containing malicious content, the application returns verbose error messages instead of generic responses. These messages can leak sensitive implementation details such as permitted file extensions, buffer sizes, or specific image processing libraries in use. This technical footprinting allows an attacker to refine exploits or bypass security filters. The issue is addressed in version 3.6.10.
