CVE-2024-34022

6.7 MEDIUM

📋 TL;DR

This vulnerability in Thunderbolt(TM) Share software allows an authenticated local user to potentially escalate privileges due to improper access control. It affects users running vulnerable versions of the software on systems with Thunderbolt hardware. The issue could let attackers gain higher system permissions than intended.

💻 Affected Systems

Products:
  • Thunderbolt(TM) Share software
Versions: Versions before 1.0.49.9
Operating Systems: Windows, Linux, macOS (if supported by Thunderbolt Share)
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Thunderbolt hardware and the software installed; default installations are vulnerable until patched.

⚠️ Manual Verification Required

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker could gain administrative or system-level privileges, enabling full control over the affected system, data theft, or further compromise.

🟠

Likely Case

A local user with standard privileges could elevate to higher permissions, potentially installing malware, accessing sensitive files, or bypassing security controls.

🟢

If Mitigated

With proper user access controls and network segmentation, impact is limited to isolated systems, reducing lateral movement and data exposure.

🌐 Internet-Facing: LOW, as exploitation requires local access and authentication, making remote attacks unlikely without prior compromise.
🏢 Internal Only: MEDIUM, because internal users or compromised accounts could exploit this to escalate privileges within a network.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW, as it involves local access and may be straightforward for authenticated users.

Exploitation details are not publicly disclosed; relies on authenticated local access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.0.49.9 or later

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01204.html

Restart Required: Yes

Instructions:

1. Visit the Intel security advisory. 2. Download and install Thunderbolt Share version 1.0.49.9 or newer. 3. Restart the system to apply changes.

🔧 Temporary Workarounds

Disable Thunderbolt Share

all

Uninstall or disable the Thunderbolt Share software to remove the vulnerable component.

sudo apt remove thunderbolt-share (Linux)
Uninstall via Control Panel (Windows)
Use system uninstaller (macOS)

Restrict Local Access

all

Limit physical and remote local access to systems using strict user authentication and access controls.

🧯 If You Can't Patch

  • Implement least privilege principles to reduce impact of privilege escalation.
  • Monitor for unusual local user activity and log access attempts.

🔍 How to Verify

Check if Vulnerable:

Check the installed version of Thunderbolt Share software; if below 1.0.49.9, it is vulnerable.

Check Version:

thunderbolt-share --version (Linux) or check in software settings (Windows/macOS)

Verify Fix Applied:

Confirm the software version is 1.0.49.9 or higher after update.
