CVE-2024-48450
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 Huly Platform v0.6.295 allows attackers to execute arbitrary code via uploading a crafted HTML file into chat group.
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 confidenceHuly Platform v0.6.295 has an arbitrary file upload vulnerability in its chat group functionality. Attackers can upload crafted HTML files which are then served by the application without proper Content-Type restrictions or sanitization, allowing the HTML to execute in user browsers leading to cross-site scripting or further client-side attacks that can escalate to arbitrary code execution.

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 Huly Platform versionCheck the installed version by inspecting package.json, version file, or running platform version command. Compare against v0.6.295Affected if Installed version is v0.6.295 or falls within the affected range around this version
-
Verify chat group functionality is enabledAccess the Huly Platform interface and navigate to chat/group messaging features, or inspect configuration files for enable_chat_groups or similar settingsAffected if Chat group functionality is active and accessible to users
-
Confirm file upload feature exists in chatOpen a chat group interface and look for attachment/upload buttons, or inspect API endpoints for chat-related file upload routes (e.g., /chat/upload, /chats/{id}/file)Affected if File upload capability is present in chat groups
-
Inspect file type validation for uploadsReview the file upload handler code or configuration to see what file types are allowed. Check for allowlist/rejectlist logic around file extensions and MIME types, specifically for HTML filesAffected if HTML files are not explicitly rejected in upload validation or allowlist is missing
-
Test how uploaded files are servedUpload a test file through chat and retrieve its URL. Use curl or browser DevTools to inspect the Content-Type and Content-Disposition headers in the HTTP responseAffected if HTML files are served with Content-Type text/html or without Content-Disposition: attachment, allowing inline execution
Environment is affected if running Huly Platform v0.6.295, chat group file upload is enabled, and uploaded HTML files can be served inline without proper Content-Type restrictions or validation.
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.
From vendor dataImplement strict allowlist-based file type validation rejecting HTML and other executable file types, serve uploaded files with Content-Type: application/octet-stream or store them outside the webroot, and add Content-Disposition: attachment headers to prevent inline rendering of untrusted files.
