CVE-2026-76633: Missing Authorization in LabRedesCefetRJ WeGIA
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.
AI Analysis
Technical Summary
CVE-2026-76633 describes an authorization bypass vulnerability in WeGIA before version 3.9.2. The vulnerability arises because the alterarSenha method is excluded from permission checks in controle/control.php, allowing authenticated users to change their password without verifying the existing password. By manipulating the redir parameter to point to alterar_senha.php, the flow routes through verificarSenhaConfig() instead of verificarSenha(), bypassing current password verification. This can convert temporary session access into permanent account takeover.
Potential Impact
An attacker with any authenticated access can change the account password without knowing the current password, leading to unauthorized account takeover. This compromises account integrity and user security, potentially allowing persistent unauthorized access.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user access and monitor for suspicious password change activities related to the alterarSenha method and redir parameter manipulation.
