Discussion

If user start-up files execute world-writable programs, especially in unprotected directories, they could be maliciously modified to destroy user files or otherwise compromise the system at the user level. If the system is compromised at the user level, it is easier to elevate privileges to eventually compromise the system at the root and network level.

Verify that SUSE operating system local initialization files do not execute world-writable programs.

Check the system for world-writable files with the following command:

> sudo find / -xdev -perm -002 -type f -exec ls -ld {} \;

For all files listed, check for their presence in the local
initialization files with the following command:

Note: The example will be for a system that is configured to create
users' home directories in the "/home" directory.

> sudo find /home/* -maxdepth 1 -type f -name \.\* -exec grep -H <file> {} \;

If any local initialization files are found to reference world-writable files, this is a finding.
