CVE-2025-3462 Overview
CVE-2025-3462 is an origin validation flaw [CWE-346] in ASUS DriverHub. The software fails to properly validate the source of incoming HTTP requests. Attackers can craft HTTP requests from unauthorized origins to interact with the DriverHub local service. ASUS confirms the issue is limited to motherboards and does not affect laptops, desktop computers, or other endpoints. Successful exploitation requires user interaction, typically through a malicious webpage that targets the DriverHub local listener. The flaw can lead to availability impact on the host system and downstream subsystems.
Critical Impact
Remote attackers can interact with ASUS DriverHub features via crafted HTTP requests, enabling abuse of driver installation functionality on affected motherboards.
Affected Products
- ASUS DriverHub (motherboard utility)
- ASUS motherboards shipping with DriverHub pre-installed
- Systems where users manually installed ASUS DriverHub

Technical Details for CVE-2025-3462
Vulnerability Analysis
ASUS DriverHub runs a local background service that exposes an HTTP interface to the host. The service is intended to receive driver management commands from the official ASUS DriverHub web property. The vulnerability stems from insufficient validation of the request Origin, allowing requests from arbitrary domains to reach privileged endpoints. An attacker who lures a user to a malicious site can issue cross-origin requests that the local service accepts as legitimate. Public research published by MrBruh demonstrates that the flaw can be chained with DriverHub's signed installer execution functionality. This chain can result in arbitrary code execution on the local system through abuse of trusted driver installation logic.
Root Cause
The root cause is improper origin validation [CWE-346] within the DriverHub local HTTP listener. The service accepts requests without strictly enforcing that the originating host matches the expected ASUS domain. Substring or loose hostname matching, rather than exact-match origin checks, expands the attack surface to attacker-controlled domains.
Attack Vector
Exploitation requires the victim to visit an attacker-controlled webpage while DriverHub is running locally. The malicious page issues crafted HTTP requests to the DriverHub listener bound on localhost. Because origin validation is insufficient, the service processes these requests as if they came from ASUS infrastructure. The attacker can then instruct DriverHub to download and execute installer payloads via its driver update workflow. For full technical details, refer to the MrBruh DriverHub writeup and the ASUS Security Advisory.
Detection Methods for CVE-2025-3462
Indicators of Compromise
- Outbound HTTP requests from browser processes targeting 127.0.0.1 or localhost on DriverHub service ports while the user is on non-ASUS domains.
- DriverHub spawning installer processes (.exe or .msi) sourced from URLs outside the official ASUS update infrastructure.
- Unexpected child processes of AsusDriverHub.exe or related DriverHub binaries.
Detection Strategies
- Hunt for process trees where the DriverHub service launches signed or unsigned installers shortly after browser activity.
- Monitor local HTTP traffic to the DriverHub listener with Origin or Referer headers from non-ASUS domains.
- Alert on driver or kernel module installations initiated by DriverHub outside of user-driven update sessions.
Monitoring Recommendations
- Enable command-line and process-creation auditing on systems running ASUS DriverHub.
- Forward endpoint telemetry to a centralized analytics platform to correlate browser activity with local installer execution.
- Track network connections from DriverHub to non-ASUS hosts and flag deviations from baseline update behavior.
How to Mitigate CVE-2025-3462
Immediate Actions Required
- Update ASUS DriverHub to the version listed in the ASUS Security Advisory or uninstall it if not required.
- Verify that the DriverHub service is not running on systems that do not need driver management.
- Restrict browser access to untrusted sites on workstations where DriverHub remains installed.
Patch Information
ASUS has released an updated DriverHub build that addresses the origin validation flaw. Refer to the "Security Update for ASUS DriverHub" section of the ASUS Security Advisory for the corrected version and download instructions. Apply the update through DriverHub's built-in updater or by reinstalling the latest package from ASUS.
Workarounds
- Uninstall ASUS DriverHub if motherboard driver management is not actively used.
- Stop and disable the DriverHub background service to prevent the local HTTP listener from accepting requests.
- Use host-based firewall rules to block inbound connections to the DriverHub listener from browser processes.
# Stop and disable the ASUS DriverHub service on Windows
sc stop "AsusDriverHubService"
sc config "AsusDriverHubService" start= disabled
# Uninstall via PowerShell (run as Administrator)
