CVE-2023-25719 (GCVE-0-2023-25719)

Vulnerability from cvelistv5 – Published: 2023-02-13 00:00 – Updated: 2025-06-19 20:35

Summary

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).

Severity ?

8.8 (High)
