CVE-2021-25146Network attack vector

Authenticated command execution via undisclosed mechanism

Published Mar 30, 2021 · Updated Aug 3, 2024

Command injection in affected Aruba Instant 6.5.x and 8.x releases allows remote authenticated users to execute operating-system commands. HPE has not published the vulnerable component, input, or command-construction operation, so the concrete injection mechanism remains undisclosed. Authentication to a network-reachable service is required, and successful exploitation grants arbitrary command execution on the access point.
