CVE-2023-48217

Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.

Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.

Validates inputs used in dynamic code generation to block injected directives.

Directly prevents execution of attacker-supplied code written into data memory regions.

Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.

Hardened configuration baselines can enforce allowed file types and processing rules.

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
