How the Exploit Works

The exploit works by taking advantage of a logic flaw in the state management of the macOS versions mentioned. The flaw, when manipulated, allows an attacker to bypass the inherent access controls and permissions, gaining unauthorized access to protected areas of the file system.

Conceptual Example Code

While the exact method of exploitation will depend on the specific configurations and usage scenarios of the targeted system, a conceptual example might involve a malicious local application or script that interacts with the file system in a way that triggers the logic flaw.

#!/bin/bash
# Conceptual shell script to exploit CVE-2025-31247
echo "Exploiting logic flaw..."
touch /protected/area/data.txt
echo "Malicious data" > /protected/area/data.txt
echo "Data written to protected area."

In the above example, a bash script is used to create and modify a file in a protected area of the file system. This should not be possible under normal conditions, but due to the logic flaw, the system allows it.
Users are strongly advised to patch their systems as soon as possible, or to use WAF/IDS as a temporary mitigation measure against this vulnerability.
