This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

WeGIA before 3.9.2 contains an authorization bypass vulnerability in the password change flow that allows any authenticated user to change their account password without providing existing credentials by exploiting the unconditional exclusion of the alterarSenha method from permission checks in controle/control.php. Attackers can manipulate the redir parameter to point to alterar_senha.php, routing through verificarSenhaConfig() instead of verificarSenha() to bypass current password verification and convert temporary session access into permanent account takeover.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
