Vulnerabilities
Expand / Collapse allIn CODESYS Development System 3.5.9.0 to 3.5.17.0 and CODESYS Scripting 4.0.0.0 to 4.1.0.0 unsafe directory permissions would allow an attacker with local access to the workstation to place potentially harmful and disguised scripts that could be executed by legitimate users.
In CODESYS Development System versions from 3.5.17.0 and prior to 3.5.19.20 a vulnerability allows for execution of binaries from the current working directory in the users context .
In multiple Codesys products in multiple versions, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpApp component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37546, CVE-2023-37547, CVE-2023-37548, CVE-2023-37549, CVE-2023-37550

This vulnerability is different to CVE-2023-37545, CVE-2023-37546, CVE-2023-37547, CVE-2023-37548 and CVE-2023-37549.
In multiple Codesys products in multiple versions, after successful authentication as a user, specially crafted network communication requests can utilize the CmpApp component to download files with any file extensions to the controller. In contrast to the regular file download via CmpFileTransfer, no filtering of certain file types is performed here. As a result, the integrity of the CODESYS control runtime system may be compromised by the files loaded onto the controller.

Mitigation
Depending on the vulnerability there are possible mitigations:
Vulnerability of CODESYS Advisory 2023-05:
- This vulnerability exists in the CODESYS programming service which is needed for commission only. Deactivate the CODESYS programming port in the web-based management if you do not need the service.
In addition to the mitigation hints CODESYS GmbH recommends the following general defense measures to reduce the risk of exploits:
- Use controllers and devices only in a protected environment to minimize network exposure and ensure they are not accessible from outside.
- Use firewalls to protect and separate the control system network from other networks.
- Use VPN (Virtual Private Networks) tunnels if remote access is required.
- Activate and apply user management and password features.
- Use encrypted communication links.
- Limit the access to both development and control system by physical means, operating system features, etc.
- Protect both development and control system by using up to date virus detection solutions.
