    Привет..
    Может кто поможет советом :)
    Windows7 рабочий. Доменный. Права так понимаю с AD..
    Компьютер блокируется через 20 минут бездействия (даже если в электропитании выключен сон и отключение монитора)
    В меню "Запрос пароля при пробуждении" выбрать "Не запрашивать пароль" не представляется возможным, т.к. имеются ограничения прав на данную настройку.
    Как бы так полулегально сделать, в тайне от администратора, чтобы комп работал и не приходилось каждый раз вводить пароль.
    Как сделать, чтобы комп не блокировался?

    1) Выполни на серваке команду "systeminfo > C:\temp\1.txt" полученный файл мне в лс.
    2) passthru вместо system, ибо system по дефолту cmd не понимает.

    1) Дай вывод sudo -l
    2) Вывод /etc/cron или файлы в cron.d
    3) что находится в tmp, opt
    4) Попробуй sudo -i (а вдруг ты уже в sudoers :))
    5) Попробуй создать symlink
    6) Попробуй скриптик http://www.securitysift.com/download/linuxprivchecker.py

    Средствами php, можно творить многие вещи. Например читать файл не через system('cat flag') а file_get_contents('flag.txt'). Получить листинг так через другие функции. а в списках запрещенных функций я не вижу eval и call_user_func. С помощью PHP ты можешь записать переменную окружения, посмотреть, а то и попробовать, прописаться в крон ну и так далее. А perl, gcc, могут быть просто не установлены. Посмотри питон, или лучше глянь папку /usr/bin, /bin, /usr/sbin и т.п. Какие интерпретаторы/компиляторы стоят теми и пробуй прокинуть reverse connect. В конечном итоге через php можно открыть сокет....

    Подскажите как дальше действовать?
    Создал пользователя с помощью DirtyCow. Но по SSH не коннектится(даже логин не спрашивает, сразу connection timeout). Есть залитый шелл(wso).
    Каким образом выполнять команды от рута? Или как сменить user:group на шелле?

    Linux version 2.6.18-408.el5 (mockbuild@builder17.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-55)) #1 SMP Tue Jan 19 08:14:00 EST 2016

    CentOS release 5.11 (Final)
    Kernel \r on an \m

    Userful: gcc, cc, ld, make, php, perl, python, ruby, tar, gzip, bzip2, nc, locate
    Danger: clamd, iptables, tripwire, logwatch
    Downloaders: wget, lynx, links, curl, lwp-mirror

    Апач - права доступа шелла nobody .
    Есть скрипты nobody и пользователя.
    При заливке шелла от nobody - будет нободи, а если от пользователя?
    Или не в зависимости от этого все права будут под 0 урезаны?

    не важно чьи скрипты,важно от чьего имени они исполняются
    если у вас есть возможность залить веб шелл от имени пользователя, то апач исполнит его от nobody,так как в конфиге апача прописано от чьего имени исполнять php
    но конфиги могут быть разными для каждого сайта, тоесть в конфиге для сайта site1 может быть прописано исполнять php скрипты от user1, а в конфиге для сайта site2 - исполнять от user2

    Здравствуйте, вопрос по рутанью Linux машин. Дело обстоит так, есть некоторые права на сервере и доступ через SSH. Есть некоторая инфа Linux localhost.localdomain 2.6.32-696.13.2.el6.i686. Вопрос: какой дальнейший шаг нужно предпринять? Искать сплоиты под ядро и учиться их юзать?
    Спасибо!
