Risk Evaluation
The CODESYS Installer is affected by a privilege escalation vulnerability. Due to a race condition, a local attacker with limited privileges can replace the verified downloaded setup before execution. Because the update process runs with administrator privileges, a malicious application can be executed with elevated rights. The attack requires the legitimate user to confirm the self‑update prompt for the CODESYS Installer itself or to initiate an installation of a CODESYS Development System. The update process for CODESYS Add-Ons is not affected by this issue.
Zusammenfassung der Gegenmaßnahmen
Update the following product to version 2.6.1.0. * CODESYS Installer The CODESYS Installer as well as the CODESYS Development System can be downloaded from the CODESYS Store. Alternatively, as well as for all other products, you will find further information on obtaining the software update in the CODESYS Update area https://www.codesys.com/download/.
