Kaseya VSA SQL Injection Vulnerability

Kaseya · Virtual System/Server Administrator (VSA)

Summary

The flaw is an SQL injection in the ConnectWise ManagedITSync integration of the Kaseya Virtual System/Server Administrator (VSA) product, exposed through its ManagedIT.asmx web page. An unauthenticated attacker who can reach that page over the network, with no user interaction required, can run arbitrary read and write SQL queries against the Kaseya VSA database.

Official description · NVD

ConnectWise ManagedITSync integration through 2017 for Kaseya VSA is vulnerable to unauthenticated remote commands that allow full direct access to the Kaseya VSA database. In February 2019, attackers have actively exploited this in the wild to download and execute ransomware payloads on all endpoints managed by the VSA server. If the ManagedIT.asmx page is available via the Kaseya VSA web interface, anyone with access to the page is able to run arbitrary SQL queries, both read and write, without authentication.
