CVE-2024-43120
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 · uneditedMissing Authorization vulnerability in XSERVER Inc. TypeSquare Webfonts allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects TypeSquare Webfonts: from n/a through 2.0.7.
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 confidenceTypeSquare Webfonts versions up to 2.0.7 contain a missing authorization vulnerability where certain functionality is not properly constrained by access control lists (ACLs). This allows unauthenticated or unauthorized users to access protected functions that should require proper authorization checks.

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 TypeSquare Webfonts versionLocate the installed version of TypeSquare Webfonts in your application or server configuration files, typically found in the product documentation, plugin settings, or version metadata file. Compare this version number against the affected range (versions up to and including 2.0.7).Affected if The installed version is 2.0.7 or lower.
-
Verify authorization controls on sensitive endpointsReview access control configurations or ACL settings for TypeSquare Webfonts to determine whether unauthenticated or unauthorized users are permitted to access protected functionality. Check if authentication is enforced on all sensitive API endpoints or functions provided by the product.Affected if ACLs are missing, misconfigured, or do not require authentication for certain protected functions.
-
Test for unauthenticated access to restricted featuresAttempt to access known sensitive functions or endpoints within TypeSquare Webfonts without providing valid credentials. Document which endpoints or functions respond successfully without authorization.Affected if Protected functions respond to unauthenticated requests, indicating missing authorization checks.
-
Review authentication enforcement mechanismInspect the application's code or configuration to confirm that authorization logic is present and properly enforced on all sensitive functions within TypeSquare Webfonts. Look for ACL validation, permission checks, or session verification.Affected if No authorization enforcement is found for certain functions, or checks are absent from key code paths.
You are affected if TypeSquare Webfonts version 2.0.7 or lower is installed AND unauthenticated users can access protected functions due to missing ACL enforcement.
