Vulnerabilities

An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.

A low-privileged remote attacker could exploit the vulnerability and inject additional system commands via file system libraries which could give the attacker full control of the device.

In multiple products of CODESYS v3 in multiple versions a remote low privileged user could utilize this vulnerability to read and modify system files and OS resources or DoS the device.

In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g.
