cwe-377-insecure-temporary-file

Fix CWE-377 by replacing predictable temporary file naming with secure Java NIO file creation. This enforces restrictive POSIX file permissions and ensures cleanup to prevent unauthorized access or data leakage.

Temporary file creation is insecure when using predictable naming patterns. Attackers can predict these paths to gain unauthorized access or cause data leakage before the application properly restricts permissions.

Create secure temporary files using Java NIO to apply POSIX file permission management. This replaces predictable naming with permission-restricted file creation, ensuring restrictive access controls and proper cleanup.

Remediate SAST findings by transforming vulnerable temporary file creation patterns into secure implementations. Replace predictable naming with Java NIO permission-restricted file creation to clear the CWE-377 vulnerability flag.

Yes, applying POSIX file permission management is required. It allows you to set restrictive permissions during file creation using Java NIO, preventing unauthorized access to the temporary files.

Java applications create permissive temporary files when using predictable naming without explicit permission restrictions. Remediating this requires secure Java NIO file creation to enforce restrictive POSIX permissions and prevent data leakage.
