Extreme Networks Aerohive HiveOS <=11.x Remote Denial of Service Exploit

Title: Extreme Networks Aerohive HiveOS <=11.x Remote Denial of Service Exploit
Advisory ID: ZSL-2020-5566
Type: Local/Remote
Impact: DoS
Risk: (3/5)
Release Date: 05.05.2020
Summary
Aerohive HiveOS is the network operating system that powers all Aerohive access points, based on a feature-rich Cooperative Control architecture. HiveOS enables Aerohive devices to organize into groups, or 'hives', which allows functionality like fast roaming, user-based access control and fully stateful application-aware firewall policies, as well as additional security and RF networking features - all without the need for a centralized or dedicated controller..
Description
An unauthenticated malicious user can trigger a Denial of Service (DoS) attack when sending specific application layer packets towards the Aerohive NetConfig UI. This PoC exploit renders the application unusable for 305 seconds or 5 minutes with a single HTTP request using the action.php5 script calling the CliWindow function thru the _page parameter, denying access to the web server hive user interface.
