CVE-2026-44468: CWE-276 Incorrect Default Permissions in CODESYS CODESYS Development System
CVE-2026-44468 is a vulnerability in CODESYS Development System version 3. 0. 0. 0 where an insecure default permission setting on a directory created during administrative installation allows a low-privileged local attacker to modify a temporary file. This file controls which components are installed, enabling the attacker to escalate privileges locally by forcing the installation of arbitrary components. The vulnerability has a high severity with a CVSS 4. 0 score of 8. 5. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
The CODESYS Development System 3.0.0.0 creates a directory with incorrect default permissions during administrative installation. This misconfiguration permits a low-privileged local user to alter a temporary file that defines the components to be installed. By modifying this file, the attacker can cause the deployment of arbitrary components, resulting in local privilege escalation. The vulnerability is tracked as CWE-276 (Incorrect Default Permissions) and has a CVSS 4.0 score of 8.5, indicating high severity. No patch or official remediation level has been published yet.
Potential Impact
A low-privileged local attacker can exploit this vulnerability to escalate privileges on the affected system by modifying installation components. This could lead to unauthorized administrative control or execution of arbitrary code with elevated privileges. There is no indication of remote exploitation or impact on confidentiality, integrity, or availability beyond local privilege escalation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only and monitor for unauthorized modification of installation files. Avoid performing administrative installations on systems where untrusted users have local access.
