CVE-2026-44468 Details
Description
The affected product creates a directory with insecure default permissions during administrative installation. This allows a low-privileged local attacker to modify a temporary file defining the components to be installed, enabling local privilege escalation by forcing the deployment of arbitrary components.
A vulnerability exists in the CODESYS Development System prior to version 3.5.22.20, where the PackageManager and IPM create temporary directories with insecure default permissions during administrative installation. This flaw allows low-privileged local attackers to modify a temporary bootstrap file, forcing the deployment of arbitrary components, or to exploit a Time-of-Check to Time-of-Use (TOCTOU) race condition by replacing digitally verified installation files with malicious ones before installation. Both issues bypass intended security boundaries during package or add-on installation.
Users are advised to update the CODESYS Development System to version 3.5.22.20. The update can be downloaded via the CODESYS Installer, from the CODESYS Store, or by visiting the CODESYS Update area for further instructions.
