CVE-2026-24070
📋 TL;DR
This vulnerability allows local privilege escalation on macOS systems running Native Access. A low-privileged user can exploit DYLIB injection in the Native Access application to execute arbitrary commands with root privileges by manipulating the privileged helper tool. This affects macOS users who have Native Access installed.
💻 Affected Systems
- Native Access
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where an attacker gains root access, can install persistent backdoors, modify system files, access all user data, and bypass all security controls.
Likely Case
Local privilege escalation allowing a standard user to gain root privileges, potentially leading to lateral movement within the network or installation of malware.
If Mitigated
Limited impact if proper application control and privilege separation are implemented, though local users could still potentially exploit the vulnerability.
🎯 Exploit Status
Exploit requires local user access but is relatively straightforward once the DYLIB injection is achieved. The vulnerability has been publicly disclosed with technical details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in CVE, but vendor should have released updated version
Vendor Advisory: https://sec-consult.com/vulnerability-lab/advisory/multiple-vulnerabilities-in-native-instruments-native-access-macos/
Restart Required: No
Instructions:
1. Update Native Access to the latest version from official sources. 2. Remove the vulnerable privileged helper tool if present. 3. Verify the application no longer has the dangerous entitlements.
🔧 Temporary Workarounds
Remove Native Access Helper Tool
macosManually remove the vulnerable privileged helper tool to prevent exploitation
sudo rm -rf /Library/PrivilegedHelperTools/com.native-instruments.NativeAccess.Helper2
sudo launchctl unload /Library/LaunchDaemons/com.native-instruments.NativeAccess.Helper2.plist
sudo rm -rf /Library/LaunchDaemons/com.native-instruments.NativeAccess.Helper2.plist
Uninstall Native Access
macosCompletely remove Native Access if not needed
sudo rm -rf /Applications/Native\ Access.app
sudo rm -rf ~/Library/Application\ Support/Native\ Instruments/Native\ Access
🧯 If You Can't Patch
- Restrict local user access to affected systems
- Implement application control to prevent execution of unauthorized binaries
- Monitor for privilege escalation attempts and file modifications in /etc/sudoers
🔍 How to Verify
Check if Vulnerable:
Check if Native Access is installed and has the vulnerable helper tool: ls -la /Library/PrivilegedHelperTools/com.native-instruments.NativeAccess.Helper2Check Version:
Check Native Access version in application info or via: /Applications/Native\ Access.app/Contents/MacOS/Native\ Access --versionVerify Fix Applied:
Verify the helper tool is removed and Native Access has been updated to a version without the dangerous entitlements📡 Detection & Monitoring
