A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of requests sent to the web interface. An attacker could exploit this vulnerability by sending a malicious request to the web interface of an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition. This vulnerability affects firmware releases prior than 1.3.7.18

Overblown Claims of Vulnerabilities, Exploits, & Severity | Huntress
Over the past few weeks, the Huntress team has been tracking the recent conversations surrounding supposed ConnectWise Control vulnerabilities and alleged in-the-wild exploitation.
We have been in contact with both the ConnectWise CISO and security team, as well as the security researcher reporting on this. While there has since been some chatter and news articles , we would like to use this article to share our own perspective.
TL;DR: We politely disagree with the threat and criticality presented by the security researcher.
The reason for this writeup is threefold:
Offer peace of mind regarding the claimed vulnerabilities in ConnectWise Control
Demonstrate proper responsible disclosure efforts and partnership between vendors
