CVE-2023-51438
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 SIMATIC IPC1047E (All versions with maxView Storage Manager < V4.14.00.26068 on Windows), SIMATIC IPC647E (All versions with maxView Storage Manager < V4.14.00.26068 on Windows), SIMATIC IPC847E (All versions with maxView Storage Manager < V4.14.00.26068 on Windows). In default installations of maxView Storage Manager where Redfish® server is configured for remote system management, a vulnerability has been identified that can provide unauthorized access.
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 confidenceThis is an authentication bypass or improper authorization vulnerability in maxView Storage Manager's Redfish server component. In default installations where Redfish is enabled for remote system management, an unauthenticated attacker can gain unauthorized access to system management functions. The CVSS 9.8 indicates network-exploitable, low-complexity attacks with complete confidentiality and integrity impact.

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.
-
Confirm maxView Storage Manager is installedLocate the maxView Storage Manager installation on the system. Check common installation directories or use system inventory tools to identify if Microchip maxView Storage Manager software is present.Affected if The software is not installed - not affected. If installed, proceed to version check.
-
Determine installed versionCheck the installed version of maxView Storage Manager. This can typically be found in the software's about section, installed programs list, or version file within the installation directory.Affected if Installed version is less than 4.14.00.26068 - vulnerable to this CVE.
-
Verify Redfish server is enabledAccess maxView Storage Manager configuration and check whether the Redfish server component is enabled. This is typically found in the server settings, remote management settings, or service configuration within the maxView administrative interface.Affected if Redfish server is enabled - the vulnerability is exploitable. If disabled, the attack surface is not present.
-
Check Redfish network accessibilityDetermine if the Redfish service port (default HTTPS port 443 or configured port) is exposed to network accessible interfaces. Use network scanning tools or review firewall rules to identify if the Redfish endpoint is reachable from untrusted networks.Affected if Redfish is enabled and accessible from network - the vulnerability is exploitable by remote unauthenticated attackers.
Affected if maxView Storage Manager version is below 4.14.00.26068 AND the Redfish server component is enabled and network-accessible, allowing unauthenticated attackers to bypass authentication.

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 · scoped4.14.00.26068
Upgrade maxView Storage Manager to version V4.14.00.26068 or later. If remote management is not required, disable the Redfish server. Apply network segmentation and access controls to limit exposure.
maxView Storage Manager V4.14.00.26068 or later
- Identify all Windows systems with maxView Storage Manager installed on SIMATIC IPC1047E, IPC647E, and IPC847E devices
- Check current maxView Storage Manager version on affected systems (typically via Add/Remove Programs or the application's About section)
- If current version is less than V4.14.00.26068, download the updated maxView Storage Manager V4.14.00.26068 or later from the Siemens cert-portal or official Siemens support channels
- Ensure the Redfish service is stopped before upgrading (if applicable)
- Install the updated maxView Storage Manager version on all affected systems
- After upgrade, verify the installed version is V4.14.00.26068 or higher
- Restart the Redfish service if it was stopped
- Confirm the maxView Storage Manager service is running correctly after upgrade
