CVE-2023-40724
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 QMS Automotive (All versions < V12.39). User credentials are found in memory as plaintext. An attacker could perform a memory dump, and get access to credentials, and use it for impersonation.
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 · high confidenceQMS Automotive versions prior to V12.39 store user credentials in memory as plaintext. An attacker with the ability to perform a memory dump can extract these credentials and use them for impersonation attacks.

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.
-
Identify QMS Automotive installation versionLocate the QMS Automotive installation directory and find the version information, typically available in the application itself, an about dialog, or version file within the program folderAffected if The installed version cannot be determined or is missing version metadata
-
Compare installed version against affected rangeReview the identified version number and compare it to the threshold V12.39 - versions prior to 12.39 are affected (for example, V12.38, V12.0, V11.x)Affected if The installed version is less than 12.39 (for example, 12.38, 12.0, 11.5)
-
Confirm QMS Automotive is in useVerify that QMS Automotive is actively installed and operational in the environment, as this vulnerability only applies to systems running the affected productAffected if QMS Automotive is not installed or is not the product in use
The environment is affected if Siemens QMS Automotive is installed and the running version is any release prior to V12.39, as these versions store credentials in plaintext in memory making them extractable via memory dump.
Generated from the published advisory. Verify against your own configuration.
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 · scoped12.39
Upgrade QMS Automotive to version V12.39 or later which addresses the plaintext credential storage in memory.
V12.39 or later
- 1. Backup your current QMS Automotive installation and database
- 2. Obtain QMS Automotive version V12.39 or later from the official Siemens support portal (cert-portal.siemens.com)
- 3. Stop the QMS Automotive service
- 4. Upgrade to V12.39 following standard installation procedures
- 5. Restart the QMS Automotive service
- 6. Verify the application is functioning normally
- 7. Confirm the vulnerability is remediated by ensuring credentials are no longer stored in plaintext in memory
