CVE-2023-37551 — Codesys Control For Beaglebone Sl security vulnerability

Medium CVSS 6.5

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.

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
