CVE-2024-27946
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). Downloading files overwrites files with the same name in the installation directory of the affected systems. The filename for the target file can be specified, thus arbitrary files can be overwritten by an attacker with the required privileges.
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 confidenceRUGGEDCOM CROSSBOW versions before V5.5 contain an arbitrary file write vulnerability in the file download functionality. An authenticated attacker with required privileges can specify a target filename to overwrite files with the same name in the product's installation directory, potentially leading to code execution or configuration tampering.

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 versionAccess the product's web interface, CLI, or system information page to retrieve the current software version numberAffected if The version is lower than V5.5 (for example, V5.4, V5.3, or earlier)
-
Verify administrative access is enabledCheck if the web management interface or CLI is accessible and confirm whether user accounts with administrative or privileged access exist on the systemAffected if Administrative or privileged user accounts are active and accessible, as the vulnerability requires authentication with required privileges
-
Confirm file download functionality is accessibleLocate the file download feature in the web interface or API endpoints (typically under system maintenance, configuration backup, or file management sections)Affected if The file download or export feature is exposed and functional without additional security restrictions
-
Review access logs for suspicious file download requestsExamine system logs, web server logs, or security audit logs for file download operations that specify custom filenames or unusual file pathsAffected if Logs show file download requests with attacker-controlled filenames, especially those targeting executable files, configuration files, or system binaries in the installation directory
You are affected if your RUGGEDCOM CROSSBOW installation is version V5.4 or earlier, the administrative interface is accessible, and the file download feature is enabled for authenticated users with privileges.
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 · scoped5.5
Upgrade to RUGGEDCOM CROSSBOW V5.5 or later, which addresses the arbitrary file overwrite vulnerability. If immediate patching is not possible, restrict administrative access and monitor for suspicious download requests.
V5.5
- Backup current Ruggedcom Crossbow configuration and data before starting the upgrade
- Obtain the V5.5 release of Ruggedcom Crossbow from the official Siemens cert-portal.siemens.com or Siemens support channels
- Follow the official Siemens upgrade procedure for Ruggedcom Crossbow to install version V5.5
- After upgrade, verify that the installation completed successfully and the path traversal vulnerability is resolved
- Restore the backed-up configuration if needed
