Summary
Several WAGO firmwares installed on different devices are impacted by various CODESYS vulnerabilities. These affect the runtime, visualization, and OPC UA server.
Impact
CVE-2025-0694:
The used OPC UA protocol supports an outdated RSA encryption scheme. This allows an unauthenticated attacker to compromise the private key of the OPC UA server and bypass authentication or decrypt transmitted data.
CVE-2025-1468:
On a device with an executed Visualization an unauthenticated attacker can access static visualization files like texts or images via the web browser.
CVE-2025-2595:
Through the SysFile component (included by the CODESYS Control runtime system) an authenticated user is able to access the local file system. An authenticated attacker could use this to set a whitelist that gives access to paths inside or outside the default directory. This is possible by using placeholder similar to environmental variables.
