CVE-2017-20102
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 · uneditedA vulnerability was found in Album Lock 4.0 and classified as critical. Affected by this issue is some unknown functionality of the file /getImage. The manipulation of the argument filePaht leads to path traversal. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used.
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 confidenceA path traversal vulnerability in Album Lock 4.0's /getImage endpoint allows local attackers to manipulate the filePaht parameter to access arbitrary files on the system using directory traversal sequences.

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 Album Lock installationLocate the Album Lock application installation directory and check the version information, typically found in the application metadata, about page, or version fileAffected if The installed version is Album Lock 4.0 exactly (= 4.0)
-
Verify /getImage endpoint existsCheck the application's web routes or source code for the /getImage endpoint handler. This is typically in the main application file or route configurationAffected if The /getImage endpoint is present and accessible in the application
-
Confirm filePaht parameter acceptanceInspect the /getImage endpoint code to verify it accepts a parameter named 'filePaht' (note the specific spelling with 'a' instead of 'th')Affected if The endpoint accepts and processes the filePaht parameter
-
Test for directory traversal vulnerabilitySend a crafted request to /getImage with filePaht parameter containing directory traversal sequences such as ../../../../etc/passwd or ../../windows/win.iniAffected if The application returns file contents from outside the intended images directory, confirming the path traversal is exploitable
A system is affected if Album Lock version 4.0 is installed, the /getImage endpoint exists, and the filePaht parameter permits directory traversal sequences to access arbitrary files.

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 filePaht parameter to reject directory traversal sequences (../) and validate that requested files are within allowed directories.
