CVE-2022-40179
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 · uneditedA vulnerability has been identified in Desigo PXM30-1 (All versions < V02.20.126.11-41), Desigo PXM30.E (All versions < V02.20.126.11-41), Desigo PXM40-1 (All versions < V02.20.126.11-41), Desigo PXM40.E (All versions < V02.20.126.11-41), Desigo PXM50-1 (All versions < V02.20.126.11-41), Desigo PXM50.E (All versions < V02.20.126.11-41), PXG3.W100-1 (All versions < V02.20.126.11-37), PXG3.W100-2 (All versions < V02.20.126.11-41), PXG3.W200-1 (All versions < V02.20.126.11-37), PXG3.W200-2 (All versions < V02.20.126.11-41). A Cross-Site Request Forgery exists in endpoints of the “Operation” web application that interpret and execute Axon language queries, due to the missing validation of anti-CSRF tokens or other origin checks. By convincing a victim to click on a malicious link or visit a specifically crafted webpage while logged-in to the device web application, a remote unauthenticated attacker can execute arbitrary Axon queries against the device.
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 analysisThe application can't tell whether a state-changing request was genuinely intended by the user, so an attacker can trick a logged-in victim's browser into making it. That can transfer funds, change settings, or create accounts silently. Remediation is anti-CSRF tokens — or equivalent same-site protections — on every state-changing request.

Firmware V02.20.126.11-41 (or V02.20.126.11-37 for PXG3.W100-1)
- 1. Identify the specific Desigo PXM device model in your deployment (PXM30-1, PXM30.E, PXM40-1, PXM40.E, PXM50-1, PXM50.E, PXG3.W100-1, or PXG3.W100-2).
- 2. Download the firmware update from the Siemens CERT portal using the link provided in the vendor advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-360783.pdf
- 3. Review the firmware release notes to confirm the fix addresses CVE-2022-40179 (CSRF protection added for Axon query endpoints).
- 4. Back up the current device configuration following Siemens backup procedures.
- 5. Upload and install the appropriate firmware version: V02.20.126.11-41 for PXM30/40/50 variants and PXG3.W100-2; V02.20.126.11-37 for PXG3.W100-1.
- 6. After upgrade, verify the device web interface is accessible and functioning normally.
- 7. Confirm the anti-CSRF tokens are now being validated by testing legitimate operations within the Operation web application.
