CVE-2020-24030
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 · uneditedForLogic Qualiex v1 and v3 has weak token expiration. This allows remote unauthenticated privilege escalation and access to sensitive data via token reuse. NOTE: as of 2025-10-14, the Supplier's perspective is that this is "not exploitable in the current implementation. Tokens are properly expired, invalidated, and bound to session context. Attempts to alter the token payload to extend its validity do not affect server-side validation."
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 confidenceForLogic Qualiex v1 and v3 contained a weak token expiration vulnerability where authentication tokens could be reused beyond their intended lifespan, enabling unauthenticated attackers to escalate privileges and access sensitive data. The vendor claims tokens in the current implementation are properly expired, invalidated, and bound to session context.

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 installed Qualiex versionLocate the Qualiex application and retrieve its version number through the application interface, about page, or installation metadata. Common methods include checking the application header, help menu, or system information panel within Qualiex.Affected if The installed version is 1.0 or 3.0 specifically, as these are the versions affected by the weak token expiration vulnerability.
-
Confirm token expiration mechanism existsAccess the authentication configuration or security settings within Qualiex. Look for settings or code that define token lifetime, expiration periods, or session timeout values.Affected if No token expiration mechanism is found, or tokens do not appear to have a defined validity period - indicating they can be reused indefinitely.
-
Verify token invalidation on logoutTest the token behavior by authenticating, obtaining a token, logging out, and then attempting to reuse the same token for a new request. Check whether the system rejects the expired token after logout.Affected if The same token remains valid after logout, meaning tokens are not being invalidated upon session termination.
-
Check token binding to session contextExamine whether tokens are bound to specific session identifiers, IP addresses, or other context variables. Attempt to use a token from a different session or context to see if it is rejected.Affected if Tokens can be reused across different sessions or contexts without validation, indicating lack of session binding.
A user is affected if Qualiex version 1.0 or 3.0 is installed and tokens lack proper expiration, invalidation, or session binding controls.

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 dataVerify the current installed version of Qualiex and confirm token validation logic enforces proper expiration, invalidation, and session binding; if on legacy versions (v1 or v3), upgrade to the current version.
