CVE-2024-36475Network attack vector

Authenticated command execution via active debug code

Published Jul 17, 2024 · Updated Aug 2, 2024

Active debug code in Century Systems FutureNet NXR, VXR, and WXR firmware allows remote authenticated users to execute OS commands. The products retain a debug function that accepts and executes operating-system commands, but the vendor has not disclosed its command parser or invocation sequence. A user must log in and know how to invoke the debug function; successful use grants command execution with the product's operating-system privileges.
