Publication date: 2025-12-11

Last updated on: 2025-12-11

Assigner: ConnectWise

Description
In versions of ScreenConnect™ prior to 25.8, server-side validation and integrity checks within the extension subsystem could allow the installation and execution of untrusted or arbitrary extensions by authorized or administrative users. Abuse of this behavior could result in the execution of custom code on the server or unauthorized access to application configuration data. This issue affects only the ScreenConnect server component; host and guest clients are not impacted. ScreenConnect 25.8 introduces enhanced server-side configuration handling and integrity checks to ensure only trusted extensions can be installed.

Executive Summary

This vulnerability exists in versions of ScreenConnect prior to 25.8, where the server-side validation and integrity checks for the extension subsystem are insufficient. This flaw allows authorized or administrative users to install and execute untrusted or arbitrary extensions on the server. As a result, attackers could run custom code on the server or gain unauthorized access to application configuration data.

Impact Analysis

The vulnerability can lead to the execution of arbitrary code on the ScreenConnect server, potentially allowing attackers to compromise the server environment. It can also result in unauthorized access to sensitive application configuration data, which could lead to further security breaches or data exposure.

Mitigation Strategies

Upgrade the ScreenConnect server component to version 25.8 or later, which includes enhanced server-side configuration handling and integrity checks to ensure only trusted extensions can be installed.

Compliance Impact

The vulnerability allows unauthorized access to application configuration data and execution of arbitrary code on the server, which could lead to breaches of confidentiality, integrity, and availability of sensitive data. Such breaches could negatively impact compliance with standards and regulations like GDPR and HIPAA that require protection of sensitive data and secure system integrity. Therefore, failure to patch this vulnerability may result in non-compliance with these regulations. [1]
