CVE-2023-52288
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 issue was discovered in the flaskcode package through 0.0.8 for Python. An unauthenticated directory traversal, exploitable with a GET request to a /resource-data/<file_path>.txt URI (from views.py), allows attackers to read arbitrary files.
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 confidenceThe flaskcode package versions up to 0.0.8 contains an unauthenticated directory traversal vulnerability in the /resource-data/<file_path>.txt endpoint in views.py. Attackers can manipulate the file_path parameter to read arbitrary files from the server's filesystem using path traversal sequences (e.g., ../../etc/passwd).

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 flaskcode package is installedRun 'pip show flaskcode' or check your project's requirements.txt/environment for the flaskcode packageAffected if flaskcode is installed with version 0.0.8 or lower
-
Verify the installed flaskcode versionExecute 'pip show flaskcode' and look for the Version field; compare against the affected range (<=0.0.8)Affected if The installed version is 0.0.8 or any version lower than 0.0.8
-
Confirm the web application is runningCheck if the flaskcode web application is actively serving requests, typically on port 5000 or a configured portAffected if The flaskcode application is running and accessible over the network
-
Test access to the vulnerable endpointSend a request to /resource-data/../../etc/passwd.txt (or similar path traversal) using curl or a browser to see if arbitrary files can be readAffected if The server returns file contents from outside the intended directory, confirming the directory traversal is exploitable
-
Check application runtime privilegesReview the process owner and file system permissions of the flaskcode application; examine what files the process can accessAffected if The application runs with privileges that allow reading sensitive system files (e.g., /etc/passwd, /etc/shadow)
A user is affected if flaskcode version 0.0.8 or lower is installed and the /resource-data endpoint is accessible, allowing unauthenticated attackers to read arbitrary files via path traversal.

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 and path sanitization on the file_path parameter to prevent directory traversal sequences, and consider restricting file access to an allowed directory whitelist.
