CVE-2024-41175
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe IPC-Diagnostics package included in TwinCAT/BSD is vulnerable to a local denial-of-service attack by a low privileged attacker.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe IPC-Diagnostics package in TwinCAT/BSD contains a local denial-of-service vulnerability that allows a low-privileged attacker to crash or disable the diagnostic service, likely through improper resource handling or service configuration.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if IPC-Diagnostics package is installedOn the TwinCAT/BSD system, run 'pkg info' or check the installed packages list for 'ipc-diagnostics' or similar diagnostic package namesAffected if The IPC-Diagnostics package is installed and its version is below 2.0.0.1
-
Determine IPC-Diagnostics package versionRun 'pkg info ipc-diagnostics' or 'pkg version' to retrieve the exact version number of the installed diagnostic packageAffected if The installed version is lower than 2.0.0.1
-
Check TwinCAT/BSD operating system versionRun 'uname -a' or check system information to identify the TwinCAT/BSD versionAffected if The TwinCAT/BSD version is lower than 14.1.2.0
-
Verify if diagnostic service is runningCheck running services using 'ps aux' or 'systemctl status' for any diagnostic-related processesAffected if The IPC-Diagnostics service is currently running on the system
-
Confirm service is accessible to low-privileged usersCheck file permissions on diagnostic service binaries and configuration files, and verify which local users have access to interact with the serviceAffected if Non-administrative users have read or execute access to the diagnostic service components
You are affected if the IPC-Diagnostics package version is below 2.0.0.1 OR TwinCAT/BSD version is below 14.1.2.0, and the diagnostic service is accessible to low-privileged local users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.0.0.114.1.2.0
Restrict local access to systems running TwinCAT/BSD to authorized administrators only, and contact Beckhoff for a patch or specific hardening guidance for the IPC-Diagnostics package.
Ipc Diagnostics Package >= 2.0.0.1 or TwinCAT/BSD >= 14.1.2.0
- 1. Identify the currently installed version of the IPC Diagnostics Package and TwinCAT/BSD on the affected system
- 2. For IPC Diagnostics Package: Upgrade to version 2.0.0.1 or later
- 3. For TwinCAT/BSD: Upgrade to version 14.1.2.0 or later
- 4. Verify the upgrade was successful by checking the installed version numbers
- 5. Test that the IPC Diagnostics functionality operates normally after the upgrade
