CVE-2024-7062

8.8 HIGH

📋 TL;DR

Nimble Commander has a privilege escalation vulnerability where the PrivilegedIOHelperV2 server fails to properly validate client authorization before executing operations. This allows attackers to execute system-level commands as root, including file manipulation and process termination. All users running vulnerable versions of Nimble Commander are affected.

💻 Affected Systems

Products:
  • Nimble Commander
Versions: Versions prior to the patched release
Operating Systems: macOS
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability affects the default installation of Nimble Commander on macOS systems.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with root-level access, allowing attackers to install persistent malware, exfiltrate sensitive data, or disrupt critical system operations.

🟠

Likely Case

Local privilege escalation leading to unauthorized file access, permission changes, and potential lateral movement within the network.

🟢

If Mitigated

Limited impact if proper network segmentation and least privilege principles are implemented, though local exploitation risk remains.

🌐 Internet-Facing: LOW
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires local access to the system but has low complexity once access is obtained.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific version

Vendor Advisory: https://pentraze.com/vulnerability-reports/CVE-2024-7062/

Restart Required: Yes

Instructions:

1. Check current Nimble Commander version
2. Visit vendor advisory for patched version
3. Download and install latest version
4. Restart the application

🔧 Temporary Workarounds

Disable PrivilegedIOHelperV2 service

macOS

Temporarily disable the vulnerable service component

sudo launchctl unload /Library/LaunchDaemons/info.filesmanager.Files.PrivilegedIOHelperV2.plist

Remove setuid permissions

macOS

Remove elevated privileges from the helper binary

sudo chmod -s /Applications/Nimble\ Commander.app/Contents/Library/LaunchServices/info.filesmanager.Files.PrivilegedIOHelperV2

🧯 If You Can't Patch

  • Restrict local user access to systems running Nimble Commander
  • Implement strict network segmentation to limit lateral movement

🔍 How to Verify

Check if Vulnerable:

Check if Nimble Commander is installed and running an unpatched version

Check Version:

Check application version in Nimble Commander About menu or via plist: defaults read /Applications/Nimble\ Commander.app/Contents/Info.plist CFBundleShortVersionString

Verify Fix Applied:

Verify installed version matches patched version from vendor advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual process execution from Nimble Commander components
  • Privilege escalation attempts in system logs

Network Indicators:

  • Unexpected network connections from Nimble Commander processes

SIEM Query:

Process execution where parent_process contains 'Nimble Commander' and command_line contains privileged operations
