CVE-2024-27944
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 RUGGEDCOM CROSSBOW (All versions < V5.5). The affected systems allow a privileged user to upload firmware files to the root installation directory of the system. By replacing specific files, an attacker could tamper specific files or even achieve remote code execution.
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 confidenceRUGGEDCOM CROSSBOW versions prior to V5.5 contain a file upload vulnerability allowing privileged users to place firmware files in the root installation directory. This improper file handling enables attackers to overwrite system files, potentially achieving remote code execution.

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 installed RUGGEDCOM CROSSbow versionCheck the application version through the web interface (typically at /about or system info page) or via CLI command 'show version' if accessible. The version is typically displayed in the login banner or system information page.Affected if The displayed version is any version prior to 5.5 (e.g., 5.4.x, 5.3.x, etc.)
-
Verify file upload functionality existsNavigate to the firmware update or file upload section of the web interface (typically under Administration, Maintenance, or System menu). Check if an upload button or form for uploading firmware files is present and accessible.Affected if The file upload interface for firmware is present and accessible to privileged users
-
Confirm privileged user account presenceReview user accounts in the user management section of the web interface. Check if any accounts with administrative or elevated privileges exist (typically labeled as Admin, Administrator, or with privilege level 15).Affected if Privileged user accounts are configured in the system
-
Check web service is accessibleConfirm the RUGGEDCOM CROSSBOW web interface is exposed and reachable on the network. This can be verified by accessing the device IP via HTTP/HTTPS.Affected if The web management interface is accessible and responding
A user is affected if they are running any version of RUGGEDCOM CROSSBOW prior to V5.5 AND the web interface with firmware upload capability is accessible to privileged users.

dbcve · scoped5.5
Upgrade RUGGEDCOM CROSSBOW to version V5.5 or later to remediate this vulnerability.
Ruggedcom Crossbow V5.5 or later
- 1. Obtain the Ruggedcom Crossbow V5.5 firmware upgrade from the official Siemens support portal (cert-portal.siemens.com) or Siemens customer support
- 2. Review the firmware upgrade documentation and release notes for any specific upgrade prerequisites
- 3. Create a backup of the current Ruggedcom Crossbow configuration before proceeding with the upgrade
- 4. Upload and apply the V5.5 firmware upgrade following the standard firmware update procedure documented in the Ruggedcom Crossbow administration guide
- 5. After the upgrade completes, verify that the system is running version V5.5 or later
- 6. Validate that the configuration has been preserved or restore from the backup if necessary
- 7. Test that normal operations and the firmware upload functionality work correctly
