# HPE Networking Fabric Composer: API missing integrity verification lets low-privilege users gain elevated privileges

HPE says the Fabric Composer API lacks an integrity verification check, so an authenticated low-privileged attacker can gain elevated privileges. Fixed in 7.4.1 and 7.3.5. HPE found it internally and knows of no public discussion or exploit code. HPE's workaround: restrict CLI and web management interfaces to a dedicated layer 2 segment/VLAN and/or firewall policies, with accounting controls.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:HPE Networking Fabric Composer affected <= 7.3.4, 7.4.0 fixed 7.3.5, 7.4.1

## How to check

Check the installed Fabric Composer version. Affected: 7.4.x up to 7.4.0 and 7.3.x up to 7.3.4 (older end-of-maintenance releases are presumed affected). Also check who can reach the management API and CLI.

## Fix

Upgrade to Fabric Composer 7.4.1 or later (7.4.x) or 7.3.5 or later (7.3.x); download from the HPE Networking Support Portal.
