Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
When a plugin is installed using the Arturia Software Center (MacOS), it also installs an uninstall.sh bash script in a root owned path. This script is written to disk with the file permissions 777, meaning it is writable by any user. When uninstalling a plugin via the Arturia Software Center the Privileged Helper gets instructed to execute this script. When the bash script is manipulated by an attacker this scenario will lead to privilege escalation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Arturia Software Center (MacOS) creates an uninstall.sh bash script with 777 permissions (world-writable) in a root-owned directory during plugin installation. When uninstalling a plugin, the Privileged Helper executes this script with root privileges. Since any local user can modify the world-writable script, an attacker can inject arbitrary commands to achieve privilege escalation to root.

MitigationThe vendor should fix the uninstall.sh script creation to use restrictive permissions (e.g., 755) and ideally verify script integrity before execution. Until a patch is available, organizations should restrict local user access to the affected directories and monitor for unauthorized modifications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if Arturia Software Center is installed
    Run: ls /Applications | grep -i 'Arturia' or check /Applications folder for Arturia Software Center.app
    Affected if Arturia Software Center is present on the system
  2. Locate uninstall.sh scripts in Arturia directories
    Run: find /Library/Application\ Support/Arturia -name 'uninstall.sh' 2>/dev/null
    Affected if One or more uninstall.sh scripts exist in Arturia directories
  3. Check permissions on uninstall.sh scripts
    Run: ls -la <path_to_uninstall.sh> for each found script, look for permissions ending in '7' for others (e.g., -rwxrwxrwx)
    Affected if The script has 777 permissions (world-writable) or permissions like -rwxrwxrwx
  4. Verify the parent directory is root-owned
    Run: ls -ld <parent_directory_of_uninstall.sh> to check ownership
    Affected if The directory containing uninstall.sh is owned by root but the script is world-writable
  5. Confirm script is executable by privileged helper
    Check if the uninstall.sh has executable bit set (ls -la shows x permissions)
    Affected if The script is executable and world-writable, meaning any user can modify code that runs as root

A user is affected if Arturia Software Center is installed and uninstall.sh scripts exist with world-writable (777) permissions in root-owned directories, allowing local privilege escalation.

Mitigation

The vendor should fix the uninstall.sh script creation to use restrictive permissions (e.g., 755) and ideally verify script integrity before execution. Until a patch is available, organizations should restrict local user access to the affected directories and monitor for unauthorized modifications.
