CVE-2020-8011Network attack vector

Unauthenticated controller crash via null pointer dereference

Published Feb 18, 2020 · Updated Aug 4, 2024

Null pointer dereference in the robot controller in DX Unified Infrastructure Management 9.20 and earlier allows remote attackers to crash it. Broadcom identifies improper probe handling that dereferences a null pointer but does not disclose the triggering message or code path. No authentication or user interaction is required; controller reachability is sufficient to interrupt monitoring by terminating the service.
