CVE-2025-55372
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 · uneditedAn arbitrary file upload vulnerability in Beakon Application before v5.4.3 allows attackers to execute arbitrary code via uploading a crafted file.
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 confidenceThis is an arbitrary file upload vulnerability in Beakon Application versions prior to v5.3.4. The flaw allows unauthenticated attackers to upload malicious files to the server, which can then be executed to achieve arbitrary code execution. The vulnerability stems from insufficient validation of uploaded file types and content.

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 Beakon Application is presentIdentify if the Beakon Application software is installed on the system by checking for its typical installation directories, services, or web endpoints. Look for processes named 'beakon' or check common installation paths for Beakon software.Affected if Beakon Application is installed and running on the system
-
Determine installed versionLocate the version information for the Beakon installation. Check configuration files, the application banner, or the software metadata that contains the version number. Compare the found version against the vulnerable range of versions prior to v5.4.3.Affected if The installed version is identified as less than 5.4.3
-
Verify web upload endpoint exposureIdentify if the application exposes a file upload interface to unauthenticated users. Review the application's web routes, endpoints, or API paths that handle file uploads. Check if these endpoints are accessible without authentication.Affected if File upload endpoints are exposed and accessible without authentication
-
Inspect upload directory contentsExamine the directories where uploaded files are stored. Look for files with potentially dangerous extensions such as .php, .asp, .jsp, .exe, or .sh in the upload location. Review file creation timestamps for recent unauthorized uploads.Affected if Executable or script files are found in upload directories, or unexpected files exist that were not intentionally uploaded by administrators
-
Check for anomalous web artifactsSearch web-accessible directories for newly created files with executable extensions or scripts that could indicate successful exploitation. Review web server logs for patterns consistent with file upload attacks.Affected if Unknown executable scripts or suspicious files appear in web-accessible locations
The environment is affected if Beakon Application version is identified as less than 5.4.3 AND the application exposes file upload functionality to users.

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 · scoped5.4.3
Update Beakon Application to v5.4.3 or later. Additionally, implement strict file type validation, content inspection, and store uploads outside the web root or with non-executable permissions.
5.4.3
- Obtain Beakon Application version 5.4.3 or later from the official vendor
- Follow standard vendor upgrade documentation for Beakon Application
- Verify the upgrade was successful by checking the installed version
- Test that the application functions normally after upgrade
