Description

WeGIA is a web manager for charitable institutions. Prior to 3.8.6, unauthenticated POST requests to web/html/socio/sistema/cadastro_cobranca.php can place a quoted SQL expression in the codigo parameter, which extract($_REQUEST) passes into the WHERE codigo= clause of an UPDATE statement without validation or parameter binding. Quoting the value bypasses MariaDB type conversion for the VARCHAR column and permits arbitrary SQL execution without a session. An attacker can read or modify database content, including user credential hashes and billing records in the cobrancas table. This issue is fixed in version 3.8.6.
