AI-suggested

European organizations should immediately update all macOS installations of Arduino IDE to version 2.3.7 or later to remediate this vulnerability. Additionally, organizations should audit and restrict local user access on macOS systems to trusted personnel only, minimizing the risk of local exploitation. Employ endpoint detection and response (EDR) solutions capable of monitoring for suspicious dynamic library injections or anomalous process behavior related to the Arduino IDE. Review and tighten TCC permissions granted to applications, ensuring the principle of least privilege is enforced. Implement macOS security best practices such as enabling System Integrity Protection (SIP) and regularly applying security patches. For environments where immediate update is not feasible, consider isolating vulnerable systems or restricting Arduino IDE usage to controlled environments. Finally, educate developers and users about the risks of running outdated software and the importance of timely updates.

Description

Arduino IDE is an integrated development environment. Prior to version 2.3.7, Arduino IDE for macOS was configured with overly permissive security entitlements that could bypass macOS Hardened Runtime protections. This configuration allows attackers to inject malicious dynamic libraries into the application process, gaining access to all TCC (Transparency, Consent, and Control) permissions granted to the application. The fix is included starting from the `2.3.7 ` release.
