Recommendation: Monitor — no exploitation signal at the moment.

ConnectWise Control before 22.9.10032 (formerly known as ScreenConnect) fails to validate user-supplied parameters such as the Bin/ConnectWiseControl.Client.exe h parameter. This results in reflected data and injection of malicious code into a downloaded executable. The executable can be used to execute malicious queries or as a denial-of-service vector. NOTE: this CVE Record is only about the parameters, such as the h parameter (this CVE Record is not about the separate issue of signed executable files that are supposed to have unique configurations across customers' installations).
