This advisory details multiple vulnerabilities found within the Kaseya BYOD Gateway software. By chaining a combination of lacking SSL verification, poor authentication mechanisms and arbitrary redirection vulnerabilities, a malicious entity may potentially compromise any Kaseya BYOD installation. The Kaseya BYOD Gateway software uses a redirection feature, wherein users are redirected to their local Kaseya installation via Kaseya’s hosted servers. The update request from the BYOD Gateway software to the Kaseya hosted servers was not found to verify SSL certificates and fails to implement any form of authentication, instead relying on the length of the gateway identifier to provide security. Thus, the security of the solution depends on an attacker’s ability to enumerate the gateway identifier. Once a malicious user enumerates the Gateway identifier, then they may update the redirect rule for that customer in Kaseya’s hosted servers, redirecting customers to a malicious Kaseya BYOD Gateway. Version 7.0.2 is affected.
