CVE-2025-22447: RemoteView Agent Privilege Escalation Flaw

CVE-2025-22447 Overview

CVE-2025-22447 is a local privilege escalation vulnerability in RemoteView Agent for Windows versions prior to v8.1.5.2. The flaw stems from incorrect access permissions assigned to a specific service [CWE-276]. A non-administrative user on a remote PC running the affected agent can leverage the misconfigured service to execute arbitrary operating system commands with LocalSystem privileges. Because RemoteView Agent is commonly installed on endpoints accessed through remote support workflows, the vulnerability is well-suited for post-authentication privilege escalation on managed hosts.

Critical Impact
A low-privileged local user can execute arbitrary OS commands as LocalSystem, resulting in full compromise of the affected Windows host.

Affected Products

RemoteView Agent for Windows versions prior to v8.1.5.2
Windows endpoints running RemoteView remote support software
Environments using RemoteView for unattended remote access

Technical Details for CVE-2025-22447

Vulnerability Analysis

The vulnerability is classified as Incorrect Default Permissions [CWE-276]. RemoteView Agent installs a Windows service that runs under the LocalSystem account. The service's access control list grants configuration or control rights to non-administrative local users. An authenticated local attacker can interact with the service to influence its execution and run arbitrary commands in the context of LocalSystem.

Exploitation requires only local access with low privileges and no user interaction. The confidentiality, integrity, and availability impact is high because LocalSystem is the most privileged account on a Windows host.

Root Cause

The RemoteView Agent service is registered with an insecure security descriptor. Standard users receive permissions such as SERVICE_CHANGE_CONFIG, SERVICE_START, or write access to service-related registry keys and binaries. These permissions allow a non-administrator to modify service properties that Windows executes under LocalSystem.

Attack Vector

An attacker with any interactive or remote session on the affected Windows host can query the vulnerable service using tools such as sc.exe or PowerShell to enumerate its Discretionary Access Control List (DACL). After confirming write access, the attacker modifies the service configuration, points its executable path or arguments to attacker-controlled logic, and triggers a service restart. Windows then launches the attacker's payload under LocalSystem. No network access, credentials for a privileged account, or user interaction are required. Additional technical detail is available in the JVN Vulnerability Report.

Detection Methods for CVE-2025-22447

Indicators of Compromise

Unexpected modifications to the RemoteView Agent service configuration, including changes to ImagePath, BinaryPathName, or service account.
New or modified files in the RemoteView installation directory written by non-administrative users.
Child processes spawned by the RemoteView Agent service that do not match legitimate binaries shipped by the vendor.

Detection Strategies

Audit the service DACL on endpoints with RemoteView Agent using sc sdshow and flag entries granting write or configuration rights to non-administrative principals.
Monitor Windows Event Log IDs 7040 (service configuration change) and 4697 (service installation) for the RemoteView Agent service.
Alert on process creation events where the RemoteView Agent service acts as a parent to cmd.exe, powershell.exe, or other interpreters.

Monitoring Recommendations

Enable command-line auditing and Sysmon Event ID 1 to capture full command lines under LocalSystem context.
Baseline the expected binary hashes and paths for the RemoteView Agent service and alert on deviations.
Correlate service modification events with the invoking user account to detect privilege escalation attempts.

How to Mitigate CVE-2025-22447

Immediate Actions Required

Upgrade RemoteView Agent for Windows to version v8.1.5.2 or later on all managed endpoints.
Inventory hosts running RemoteView Agent and prioritize patching multi-user or shared workstations first.
Review the service DACL after patching to confirm non-administrative users no longer hold configuration rights.

Patch Information

The vendor has released a fixed build in RemoteView Agent v8.1.5.2. Deployment guidance and patch scope are documented in the Rview Emergency Patch Overview and the JVN Vulnerability Report.

Workarounds

Where immediate patching is not possible, restrict interactive and remote logon rights on affected hosts to trusted administrators only.
Manually harden the service DACL using sc sdset to remove write and configuration permissions for Authenticated Users and Users groups.
Uninstall RemoteView Agent from endpoints that no longer require remote support until the fixed version is deployed.

bash

# Configuration example: inspect and harden the RemoteView Agent service DACL
sc.exe sdshow RemoteViewAgent

# Restrict service access to SYSTEM and Administrators only
sc.exe sdset RemoteViewAgent "D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCLCSWRPWPDTLOCRRC;;;BA)(A;;CCLCSWLOCRRC;;;IU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)"
