The issue allows remote attackers to inject arbitrary web script or HTML. This can be achieved via several parameters, including `errorNo` and `errorMsg` in the error.php endpoint "/error.php", `viewType` in the duplicate manager.php endpoint "/duplicate manager.php", and multiple parameters in the query manager.php endpoint "/query manager.php", such as `queryAction`, `displayType`, `citeOrder`, `sqlQuery`, `showQuery`, `showLinks`, `showRows`, and `queryID`. Additionally, the `sourceText` and `sourceIDs` parameters in the import.php endpoint "/import.php", and the `typeName` and `fileName` parameters in the modify.php endpoint "/modify.php" are also vulnerable.
