CVE-2024-52400
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 Upload of File with Dangerous Type vulnerability in Subhasis Laha Gallerio gallerio allows Upload a Web Shell to a Web Server.This issue affects Gallerio: from n/a through <= 1.01.
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 Gallerio application (version 1.01 and below) that allows attackers to upload executable files (web shells) directly to the web server. The lack of proper file type validation and secure storage allows remote code execution through the uploaded malicious scripts.

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 Gallerio application is installedSearch for Gallerio installation directories, check web server document roots for gallerio folders, or review application inventory/software listAffected if Gallerio version 1.01 or below is found on the system
-
Determine the installed Gallerio versionLocate version information in application files such as version.php, about page, or configuration files, and compare against 1.01Affected if Installed version is 1.01 or any version below 1.01
-
Verify if the file upload feature is enabledCheck Gallerio configuration settings or admin panel for upload-related options; look for upload forms or endpoints in the web directoryAffected if File upload functionality is accessible and enabled in the application
-
Inspect upload directory locationExamine web server configuration and Galleria settings to determine where uploaded files are stored relative to the web rootAffected if Upload directory is located within the web root or publicly accessible path
-
Check file type validation configurationReview application source code, configuration files, or admin settings for file type/mime-type validation logic for uploadsAffected if No file type validation or only client-side validation is implemented, or if executable extensions are allowed
Your environment is affected if Gallerio version 1.01 or below is installed with the upload feature enabled and without proper file type validation and secure upload directory 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.
From vendor dataImplement strict file type validation (allowlist approach), store uploads outside the web root, rename uploaded files, and disable script execution in upload directories.
