Codesys: >> Development System >> 3.0 Security Vulnerabilities
The affected product extracts installation files to a temporary directory with incorrect default permissions during administrative installation. A low-privileged local attacker can exploit a TOCTOU race condition with a practical time window to replace verified files with malicious ones before installation, resulting in local privilege escalation.

The affected product creates a directory with insecure default permissions during administrative installation. This allows a low-privileged local attacker to modify a temporary file defining the components to be installed, enabling local privilege escalation by forcing the deployment of arbitrary components.

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-2023-37545, CVE-2023-37546, CVE-2023-37547, CVE-2023-37548 and CVE-2023-37550

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.
