The underlying weakness: Creation of Temporary File in Directory with Insecure Permissions
The product creates a temporary file in a directory whose permissions allow unintended actors to determine the file's existence or otherwise access that file.
How developers prevent this class of flaw
- Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.
- Try to store sensitive tempfiles in a directory which is not world readable -- i.e., per-user directories.
- Avoid using vulnerable temp file functions.
