CVE-2025-0471
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 · uneditedUnrestricted file upload vulnerability in the PMB platform, affecting versions 4.0.10 and above. This vulnerability could allow an attacker to upload a file to gain remote access to the machine, being able to access, modify and execute commands freely.
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 unrestricted file upload vulnerability in the PMB platform affecting versions 4.0.10 and above. The flaw allows attackers to upload arbitrary files (such as malicious scripts) to the server, enabling remote code execution and complete compromise of the affected system.

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 PMB is installedLocate the PMB application installation directory and check for the presence of PMB core files (such as opac_css, includes, or similar PMB-specific directories)Affected if PMB software is present on the system
-
Check the installed PMB versionLook for a version file or check the database/configuration for the PMB version number; compare it to the affected range of >= 4.0.10Affected if The installed version is 4.0.10 or higher
-
Determine if file upload functionality is exposedReview the PMB configuration and routing to identify if file upload endpoints (for user uploads, document uploads, or avatar uploads) are accessible without proper restrictionsAffected if File upload endpoints are accessible to unauthenticated or insufficiently authenticated users
-
Check where uploaded files are storedInspect the PMB configuration to determine the upload directory path and whether it resides within the web root (htdocs, www, public_html)Affected if Uploaded files are stored in a web-accessible directory without randomization or execution prevention
-
Verify authentication on upload endpointsReview the access control settings for upload-related scripts or endpoints in the PMB installationAffected if Upload functionality can be accessed without proper authentication or authorization checks
The environment is affected if PMB version 4.0.10 or higher is installed and file upload functionality is accessible without proper validation and authentication 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.
From vendor dataImplement strict file type validation using a whitelist approach, store uploaded files outside the web root with randomized filenames, enforce proper authentication and authorization on upload endpoints, and apply appropriate file system permissions.
