CVE-2026-24070: CWE-426 Untrusted Search Path in Native Instruments Native Access
During the installation of the Native Access application, a privileged helper `com.native-instruments.NativeAccess.Helper2`, which is used by Native Access to trigger functions via XPC communication like copy-file, remove or set-permissions, is deployed as well. The communication with the XPC service of the privileged helper is only allowed if the client process is signed with the corresponding certificate and fulfills the following code signing requirement: "anchor trusted and certificate leaf[subject.CN] = \"Developer ID Application: Native Instruments GmbH (83K5EG6Z9V)\"" The Native Access application was found to be signed with the `com.apple.security.cs.allow-dyld-environment-variables` and `com.apple.security.cs.disable-library-validation` entitlements leading to DYLIB injection and therefore command execution in the context of this application. A low privileged user can exploit the DYLIB injection to trigger functions of the privileged helper XPC service resulting in privilege escalation by first deleting the /etc/sudoers file and then copying a malicious version of that file to /etc/sudoers.
AI Analysis
Technical Summary
CVE-2026-24070 is a high-severity vulnerability in Native Instruments Native Access where the application’s use of the entitlements 'com.apple.security.cs.allow-dyld-environment-variables' and 'com.apple.security.cs.disable-library-validation' permits DYLIB injection. This injection allows a low privileged user to execute commands within the application context and interact with a privileged helper XPC service that requires strict code signing. By exploiting this, an attacker can delete the /etc/sudoers file and replace it with a malicious version, achieving privilege escalation. The vulnerability stems from an untrusted search path (CWE-426) during installation and the insecure entitlements granted to the application. There is no vendor advisory or patch information available at this time.
Potential Impact
Successful exploitation allows a low privileged user to escalate privileges to root by manipulating the privileged helper service to delete and replace the /etc/sudoers file. This results in full system compromise with high confidentiality, integrity, and availability impacts as indicated by the CVSS score of 8.8.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid running Native Access in environments where untrusted users have local access. Monitor for updates from Native Instruments regarding an official fix or workaround.
