CVE-2024-31552
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 · uneditedCuteHttpFileServer v.3.1 version has an arbitrary file download vulnerability, which allows attackers to download arbitrary files on the server and obtain sensitive information.
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 confidenceCuteHttpFileServer v3.1 contains an arbitrary file download vulnerability, likely a path traversal flaw where the application fails to properly validate file path inputs, enabling attackers to use directory traversal sequences (e.g., '../') to access and download files outside the intended web root directory, 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.
-
Confirm CuteHttpFileServer is installedIdentify the httpfile server process or executable on the system using process listing (tasklist on Windows, ps on Linux) or by locating the httpfile server binary/web root directory.Affected if The application httpfileserver or httpfserver process is running on the system.
-
Determine the installed versionRun the server binary with a version flag (commonly -v, -version, or --version) or inspect the binary metadata, or check the server banner if exposed via HTTP headers or the web interface.Affected if The version is 3.1 or falls within the vulnerable release range.
-
Verify file serving is enabledCheck the server configuration file (often chfs.ini, config.ini, or similar in the application directory) for settings that enable file sharing/download functionality.Affected if File download or sharing features are enabled in the configuration.
-
Check network exposureReview firewall rules or binding configuration to determine if the HTTP service is bound to a reachable network interface (0.0.0.0) rather than localhost only.Affected if The service is exposed to network-accessible IP addresses.
-
Test for path traversal vulnerabilitySend an HTTP request with a traversal sequence (such as GET /..%2F..%2F..%2Fetc%2Fpasswd or GET /..\/..\/windows\/system32\/config\/sam) to the server and observe if arbitrary files are returned.Affected if The server returns files outside the intended shared directory in response to traversal sequences.
A user is affected if CuteHttpFileServer version 3.1 or vulnerable version is running with file serving enabled and the server responds to path traversal requests with files outside the intended web root.

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 dataIf a patched version is available, upgrade immediately. Otherwise, implement strict input validation and path canonicalization to prevent traversal sequences, combined with network isolation and least-privilege file system permissions to limit exposure.
