CVE-2024-13991
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 · uneditedHuijietong Cloud Video Platform contains a path traversal vulnerability that allows an unauthenticated attacker can supply arbitrary file paths to the `fullPath` parameter of the `/fileDownload?action=downloadBackupFile` endpoint and retrieve files from the server filesystem. VulnCheck has observed this vulnerability being exploited in the wild.
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 confidenceHuijietong Cloud Video Platform has a path traversal vulnerability in the /fileDownload endpoint with the downloadBackupFile action. The fullPath parameter does not properly validate or sanitize file path inputs, allowing unauthenticated attackers to use traversal sequences (e.g., ../../) to access arbitrary files outside the intended directory, potentially exposing sensitive system files.

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 Huijietong Cloud Video Platform is deployedCheck your running services, web applications, or installed software for the presence of Huijietong Cloud Video Platform. Look for associated web directories, services, or binaries related to this product.Affected if The platform is not present in your environment, then you are not affected.
-
Locate the /fileDownload endpointScan your web application or API for the endpoint /fileDownload (e.g., https://yourhost/fileDownload or http://yourhost:port/fileDownload). Use web vulnerability scanners or manual HTTP requests to probe for this path.Affected if The endpoint returns a valid HTTP response (200, 400, or similar) rather than 404, indicating the endpoint exists and is accessible.
-
Verify the downloadBackupFile action is availableSend an HTTP GET or POST request to /fileDownload with the parameter action=downloadBackupFile (e.g., /fileDownload?action=downloadBackupFile). Check if the application accepts this action parameter.Affected if The application accepts the action parameter and responds without rejecting it, indicating the vulnerable functionality is present.
-
Test if the fullPath parameter accepts path traversalSend a request with fullPath=../../../../etc/passwd or similar traversal sequence (e.g., /fileDownload?action=downloadBackupFile&fullPath=../../../../etc/passwd). Observe if the application returns file contents or allows reading outside the intended directory.Affected if The application returns file contents from outside the intended directory, confirming the path traversal vulnerability is exploitable.
If the Huijietong Cloud Video Platform is deployed AND the /fileDownload endpoint with downloadBackupFile action is accessible AND the fullPath parameter accepts path traversal sequences to read arbitrary files, then your environment is affected by this CVE.

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 input validation on the fullPath parameter to reject path traversal sequences and restrict file access to allowed directories only, or temporarily block access to the vulnerable endpoint until a patch is applied.
