== Sensitive Code Example

----
new File("/tmp/myfile.txt"); // Sensitive
Paths.get("/tmp/myfile.txt"); // Sensitive

java.io.File.createTempFile("prefix", "suffix"); // Sensitive, will be in the default temporary-file directory.
java.nio.file.Files.createTempDirectory("prefix"); // Sensitive, will be in the default temporary-file directory.
----

----
Map<String, String> env = System.getenv();
env.get("TMP"); // Sensitive
----

== Compliant Solution

----
new File("/myDirectory/myfile.txt");  // Compliant

File.createTempFile("prefix", "suffix", new File("/mySecureDirectory"));  // Compliant

if(SystemUtils.IS_OS_UNIX) {
  FileAttribute<Set<PosixFilePermission>> attr = PosixFilePermissions.asFileAttribute(PosixFilePermissions.fromString("rwx------"));
  Files.createTempFile("prefix", "suffix", attr); // Compliant
}
else {
  File f = Files.createTempFile("prefix", "suffix").toFile();  // Compliant
  f.setReadable(true, true);
  f.setWritable(true, true);
  f.setExecutable(true, true);
}
