Hey,
well ive gotten into some box , yet i cant really execute anything usefull for me.
I exploited the forum, waraxe cracked the hash for me, and i uploaded my shell there 
Though i cant add user (using net.exe ) nor can i start/stop any service, cant really execute anything at all.
Any idea why?
Rights on every file are drwxrwxrwx , tho i cant delete them somehow, i can write to them tho.
Really weird  |

What version of windows? Win2k? Win2k3? Other?
It's obvious, that you need to find out your current username/sid and your privileges. And from what platform you got shell - apache/php? IIS/php? |

How about php shell functions: exec(), system(), passthru(), popen(), proc_open(), pcntl_exec()? Are they working at some degree? Try "dir" as test command. Look for php info: "safe_mode", "disable_functions"?
And as you can manipulate some files and directories in server, then there are other possibilities - ASP, CGI, Perl, Python - depends on specific server environment.
And of course even after getting into windows command prompt you still have minimal privileges. So adding users, writing critical files, etc - it's just a dream, unless you find a way for local privilege escalation |

all functions are enabled and secure mode is off, still, when you execute even a simple dir command you get 126 as output... I thinks it has something to do with output redirection idk, studying on it.
Escalating priviledges to SYSTEM on a windows machine is easy as stealing cookies to children... there's a local priv escalation exploit on nt boxes within the kernel that microsoft won't fix for win32 under vista (2k,xp,2k3..). And there's another one on vista that microsoft won't fix coz it's a matter of rewriting part of the kernel. |
