find . -type d -perm 777 -exec chmod 755 {} \; (for changing the directory permission)

find . -type f -perm 777 -exec chmod 644 {} \; (for changing the file permission)

If they did not have 777 permissions, we easily remove the -perm 777 part.

Regardless of the permissions:

chmod -R a=r,a+X,u+w /your/path
