In July, Kaseya announced three new zero-day vulnerabilities impacting its Kaseya Unitrends service. The vulnerabilities were represented by an authenticated RCE flaw on the server, a privilege escalation flaw from read-only user to admin on the server, and an undisclosed issue on the client side.

“The Dutch Institute for Vulnerability Disclosure (DIVD) performs a daily scan to detect vulnerable Kaseya Unitrends servers and notify the owners directly or via the known abuse channels, Gov-CERTs and CSIRTs, and other trusted channels,” according to the original advisory.

Unitrends customers are advised to patch the vulnerable servers and apply the mitigations for the client-side issue.
