CVE-2020-0583

8.8 HIGH

📋 TL;DR

This vulnerability allows an authenticated user on a local system to potentially escalate privileges due to improper access control in Intel Smart Sound Technology. It affects systems with specific 8th and 10th Generation Intel Core processors running vulnerable versions of the Smart Sound Technology driver. Attackers could gain higher system privileges than intended.

💻 Affected Systems

Products:
  • Intel Smart Sound Technology driver
Versions: Versions before 3431 for 10th Generation Intel Core i7 Processors, versions before 3349 for 8th Generation Intel Core Processors
Operating Systems: Windows, Linux (potentially)
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems with specific Intel processors that include Smart Sound Technology. The vulnerability is in the driver software, not the hardware itself.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker could gain SYSTEM/root privileges, install malware, steal sensitive data, or maintain persistent access to the compromised system.

🟠

Likely Case

Local authenticated users (including malware or compromised accounts) could elevate privileges to install additional malicious software or access restricted system resources.

🟢

If Mitigated

With proper privilege separation and least privilege principles, impact is limited to the compromised user account's scope rather than full system compromise.

🌐 Internet-Facing: LOW - This vulnerability requires local access and authenticated user context, making remote exploitation unlikely without additional attack vectors.
🏢 Internal Only: HIGH - This is primarily an internal threat where authenticated users (including compromised accounts) could exploit the vulnerability to escalate privileges on affected systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires local access and authenticated user credentials. No public exploit code has been disclosed as of the advisory date.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version 3431 for 10th Generation Intel Core i7 Processors, Version 3349 for 8th Generation Intel Core Processors

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00354.html

Restart Required: Yes

Instructions:

1. Visit Intel's security advisory page. 2. Download the updated Intel Smart Sound Technology driver for your specific processor generation. 3. Install the driver update. 4. Restart the system to complete the installation.

🔧 Temporary Workarounds

Restrict local user privileges

all

Implement least privilege principles to limit what authenticated users can do, reducing the impact of successful exploitation.

Disable Intel Smart Sound Technology

all

If not required, disable the Intel Smart Sound Technology feature in BIOS/UEFI settings or device manager.

🧯 If You Can't Patch

  • Implement strict access controls and monitor for privilege escalation attempts
  • Segment affected systems from critical infrastructure and apply network isolation where possible

🔍 How to Verify

Check if Vulnerable:

Check Intel Smart Sound Technology driver version in Device Manager (Windows) or via system information tools. Compare against vulnerable versions listed in the advisory.

Check Version:

Windows: Check Device Manager > Sound, video and game controllers > Intel(R) Smart Sound Technology driver properties. Linux: Check with appropriate driver management tools for your distribution.

Verify Fix Applied:

Verify the driver version has been updated to 3431 or higher for 10th Gen i7, or 3349 or higher for 8th Gen processors.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected privilege escalation events
  • Driver loading failures or anomalies
  • Access control violations in system logs

Network Indicators:

  • None - this is a local privilege escalation vulnerability

SIEM Query:

Search for Event ID 4672 (Special privileges assigned to new logon) or equivalent privilege escalation events from non-administrative users on affected systems.
