CVE-2025-7973 in FactoryTalk ViewPoint
Summary
by MITRE • 08/14/2025
A security issue exists in FactoryTalk ViewPoint version 14.0 or below due to improper handling of MSI repair operations. During a repair, attackers can hijack the cscript.exe console window, which runs with SYSTEM privileges. This can be exploited to spawn an elevated command prompt, enabling full privilege escalation.

The vulnerability identified as CVE-2025-7973 represents a critical privilege escalation flaw within FactoryTalk ViewPoint version 14.0 and earlier releases. This security issue stems from inadequate handling of Windows Installer (MSI) repair operations, which are commonly used to fix or reinstall software components. The flaw specifically manifests during the repair process when the system executes cscript.exe with elevated SYSTEM privileges, creating an exploitable window for malicious actors to gain full administrative control over affected systems.
The technical exploitation of this vulnerability leverages the inherent trust relationships within Windows installer processes and the elevated privilege context in which cscript.exe operates during MSI repair operations. When an attacker initiates a repair operation, the malicious code can hijack the cscript.exe console window that executes with SYSTEM privileges, effectively allowing the attacker to spawn an elevated command prompt. This represents a classic privilege escalation vector where a lower-privileged user can leverage a flaw in the software installation and repair mechanism to achieve full system compromise. The vulnerability directly maps to CWE-787: Out-of-bounds Write and CWE-20: Improper Input Validation, as it involves improper handling of system repair operations and inadequate validation of execution contexts.
The operational impact of CVE-2025-7973 extends beyond simple privilege escalation, as it provides attackers with complete control over industrial control systems that rely on FactoryTalk ViewPoint for visualization and monitoring. Organizations using this software in manufacturing environments, process control systems, or critical infrastructure applications face severe consequences, as the elevated privileges gained through this exploit could enable attackers to modify operational parameters, disable security controls, or deploy additional malicious payloads. The vulnerability is particularly concerning in environments where FactoryTalk ViewPoint is used for critical process monitoring, as it could potentially lead to operational disruptions, safety hazards, or unauthorized access to sensitive industrial processes.
Mitigation strategies for CVE-2025-7973 should focus on immediate software updates and operational controls to prevent exploitation. Organizations must prioritize updating FactoryTalk ViewPoint to versions that address this vulnerability, as the manufacturer is likely to have released patches that correct the improper handling of MSI repair operations. System administrators should also implement additional controls such as restricting user access to repair operations, monitoring for unusual cscript.exe executions, and implementing least privilege principles for installer operations. From an ATT&CK framework perspective, this vulnerability aligns with T1068: Exploitation for Privilege Escalation and T1547.001: Registry Run Keys / Startup Folder, as it leverages system installation mechanisms to achieve elevated privileges. Network segmentation and endpoint detection and response solutions should be deployed to monitor for suspicious repair operations and unauthorized privilege escalation attempts.
