Taint — модуль определения кодов XSS (испорченные или подозрительные строки, tainted strings).
|
|
Также может быть полезен для выявления попыток внедрения SQL-инъекций,
|
|
shell-инъекций и т. д.
|
|
</para>
|
|
<para>
|
|
Если модуль включён, то когда вы передаёте подозрительную строку
|
|
(из $_GET, $_POST или $_COOKIE) некоторым функциям, будет
|
|
выдано предупреждение.
