CVE-2025-15228
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 · uneditedBPMFlowWebkit developed by WELLTEND TECHNOLOGY has a Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.
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 confidenceBPMFlowWebkit by WELLTEND TECHNOLOGY contains an arbitrary file upload vulnerability allowing unauthenticated remote attackers to upload malicious files, specifically web shell backdoors, leading to arbitrary code execution on the server.

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 if BPMFlowWebkit is deployedSearch for Welltend BPMFlowWebkit components in your environment, including web application directories, installed packages, or running servicesAffected if BPMFlowWebkit by WELLTEND TECHNOLOGY is present in the environment
-
Determine the installed versionLocate version information for the Welltend BPMFlowWebkit installation through application metadata, about pages, or system inventory toolsAffected if The installed version is lower than 5.0.5 (any version < 5.0.5)
-
Verify file upload endpoint accessibilityIdentify if the file upload functionality is exposed and accessible without authentication by checking the application's authentication configuration and exposed web endpointsAffected if The file upload feature can be accessed without any authentication credentials
-
Inspect file upload validation configurationReview the application's file upload validation settings, including allowed file type restrictions and filename sanitization rulesAffected if File type allow-listing is not implemented or can be bypassed, or no filename sanitization is performed
-
Check upload storage configurationVerify where uploaded files are stored relative to the web root and whether execute permissions are restrictedAffected if Uploaded files are stored within the web root directory or can be executed
The environment is affected if Welltend BPMFlowWebkit version lower than 5.0.5 is installed and the file upload feature is accessible without authentication or proper validation controls.

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 · scoped5.0.5
Implement strict file upload validation including authentication requirements, file type allow-listing, filename sanitization, and store uploads outside the web root with no execute permissions.
5.0.5 or later
- 1. Back up the current BPMFlowWebkit installation and database before proceeding with any upgrade.
- 2. Obtain the latest version (5.0.5 or later) from the vendor WELLTEND TECHNOLOGY or your authorized distribution channel.
- 3. Review the release notes and upgrade documentation for version 5.0.5.
- 4. Stop the BPMFlowWebkit service.
- 5. Deploy the new version (5.0.5 or later) following the vendor's upgrade instructions.
- 6. Verify that file upload functionality now properly validates file types and content.
- 7. Restart the BPMFlowWebkit service.
- 8. Test that arbitrary file upload is no longer possible and legitimate file uploads still work.
