Summary
CODESYS: Multiple products affected by WIBU Codemeter vulnerability
Notes
Summary: Several CODESYS setups contain and install vulnerable versions of the WIBU CodeMeter Runtime.
Impact: The CODESYS Development System is an IEC 61131-3 programming tool for PLCs based on the CODESYSControl runtime system, which enables embedded or PC-based devices to be a programmable industrialcontroller. All affected CODESYS products install and use the WIBU CodeMeter Runtime for licensemanagement. The manufacturer WIBU-SYSTEMS AG has reported a heap buffer overflow vulnerability in theWIBU CodeMeter Runtime, which can potentially lead to a remote code execution.
Mitigation: WIBU-SYSTEMS AG recommends updating to CodeMeter Runtime version 7.60c to fix the vulnerability. Until an update is available for the affected CODESYS products or if this is not to be installed, CODESYS GmbH recommends downloading and installing the current CodeMeter Runtime directly from the website of WIBU-SYSTEMS AG (https://www.wibu.com/support/user/user-software.html). If neither an update of the affected CODESYS products nor an update of the WIBU CodeMeter Runtime can be performed, you may find further mitigations in the Security Advisory WIBU-230704-01 provided by WIBUSYSTEMS AG (https://www.wibu.com/support/security-advisories.html).
Remediation: Update the following products to version 3.5.19.30. • CODESYS Control RTE (SL) • CODESYS Control RTE (for Beckhoff CX) SL • CODESYS Control Win (SL) • CODESYS HMI (SL) • CODESYS Development System • CODESYS OPC DA Server SL Update the following products to version to 4.10.0.0. • CODESYS Control for Linux SL • CODESYS Control for Linux ARM SL For the legacy CODESYS V2 products, no new version is scheduled.
CVE-2023-3935

A heap buffer overflow vulnerability in Wibu CodeMeter Runtime network service up to version 7.60b allows an unauthenticated, remote attacker to achieve RCE and gain full access of the host system.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-787 - Out-of-bounds Write
Mitigation WIBU-SYSTEMS AG recommends updating to CodeMeter Runtime version 7.60c to fix the vulnerability. Until an update is available for the affected CODESYS products or if this is not to be installed, CODESYS GmbH recommends downloading and installing the current CodeMeter Runtime directly from the website of WIBU-SYSTEMS AG (https://www.wibu.com/support/user/user-software.html).
