Lifecycle Timeline
2DescriptionGitHub Advisory
WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, the script in adicionar_tipo_docs_atendido.php does not go through the project's central controller and does not have its own authentication and permission checks. A malicious user could make a request through tools like Postman or the file's URL on the web to access features exclusive to employees. The vulnerability allows external parties to inject unauthorized data in massive quantities into the application server's storage. Version 3.6.5 fixes the issue.
Executive ViewAI
WeGIA instances prior to version 3.6.5 contain a critical authentication bypass vulnerability affecting charitable institutions' web managers. An unauthenticated attacker can exploit the adicionar_tipo_docs_atendido.php script to gain unauthorized access and manipulate document type configurations, potentially compromising sensitive beneficiary and organizational data.
Implement Web Application Firewall (WAF) rules to block access to adicionar_tipo_docs_atendido.php; restrict network access to WeGIA administrative interfaces using IP whitelisting and network segmentation; disable the document type management feature if operationally feasible; enforce mandatory authentication at reverse proxy/load balancer level; implement continuous monitoring and alerting for unauthorized access attempts to the vulnerable endpoint; consider disabling the WeGIA service entirely until patch availability is confirmed.
