How to find world writable files in Linux? In Linux, a file “world writable” is a file which everyone can write. These files can be used as sensitive by people who did not aim at the base to write data to the system or out of a given directory. The world writable files are more dangerous when they can run by anyone on the system, as they can then make a script. Today, we will see how easily we can locate these files on a Linux system through the command “Find” that is available on the most of Linux systems. Using the Find command: To find the world writable files on a Linux system, just use the following command: | find / -type f! -path "/ proc / *" -prune -perm o + w exec ls {} -lg /; 2> / dev / null Then we will back all world writable system files and display their rights, their owner and their full path: For those who wish to understand the command: Find command search files in a directory for the fact that we specify here as the root “/” | "-type" specifies the type of object you are looking for. "F" for file and "d" for directory | " ! path "/ proc / *" -prune "to exclude the" / proc " which always takes a lot of profit | "perm" used to search a given permission, here 'o + w” or "2" that is the octal value of the license "w" write for "other" users | "- exec 'to execute a command | " -lg ls {} " will list the files in a list format (" l ") without displaying the owner - (" g ") from the root | " 2> / dev / null " is used to redirect errors to a null file For those who quickly grasped the principle of command and options used, it is entirely possible to use it to find the files "world readable" files / folders according to specific rights or rule of other folders.
