CVE-2024-41174
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 in TwinCAT/BSD is susceptible to improper input neutralization by a low-privileged local 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 Beckhoff's TwinCAT/BSD operating system contains an improper input neutralization vulnerability. A low-privileged local attacker can exploit insufficient input validation to potentially escalate privileges or inject malicious input, as indicated by the CVSS 7.3 HIGH severity rating.
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 IPC-Diagnostics package versionAccess the Beckhoff TwinCAT/BSD system and run the package manager or system information command to list installed packages and their versions. Look for 'Ipc Diagnostics Package' or similar diagnostic package entries.Affected if The installed IPC-Diagnostics package version is lower than 2.1.1.0
-
Check TwinCAT/BSD operating system versionOn the TwinCAT/BSD system, run 'uname -a' or check system information to identify the OS version. Look for TwinCAT/BSD version information.Affected if The TwinCAT/BSD version is lower than 14.1.2.0
-
Verify IPC-Diagnostics service statusCheck if the IPC-Diagnostics service or daemon is running on the system. This may involve checking system services, running processes, or listening network ports related to diagnostics functionality.Affected if The IPC-Diagnostics service is active and accessible to low-privileged users
-
Check IPC-Diagnostics configuration and permissionsExamine the configuration files and permission settings for the IPC-Diagnostics package. Look for any configuration that controls input validation, user access controls, or privilege levels.Affected if Input validation settings are weak or low-privileged users have access to diagnostic input interfaces
A system is affected if it runs TwinCAT/BSD with an IPC-Diagnostics package version below 2.1.1.0 or TwinCAT/BSD version below 14.1.2.0, and the IPC-Diagnostics feature is enabled and accessible.

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 · scoped2.1.1.014.1.2.0
Apply vendor-supplied patches for TwinCAT/BSD when available. As an interim measure, restrict local access to trusted personnel only and monitor IPC-Diagnostics package usage for anomalous behavior.
IPC Diagnostics Package 2.1.1.0 or TwinCAT/BSD 14.1.2.0
- 1. Identify the currently installed version of the IPC Diagnostics Package or TwinCAT/BSD on the affected system
- 2. If using IPC Diagnostics Package, upgrade to version 2.1.1.0 or later
- 3. If using TwinCAT/BSD, upgrade to version 14.1.2.0 or later
- 4. Verify the upgrade was successful by checking the installed version number
- 5. Test the IPC Diagnostics functionality to confirm the XSS vulnerability has been remediated
