CVE-2025-54542
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 · uneditedQuickCMS sends password and login via GET Request. This allows a local attacker with access to the victim's browser history to obtain the necessary credentials to log in as the user. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.8 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
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 confidenceQuickCMS transmits user credentials (username and password) as URL query parameters in GET requests during authentication. These credentials are stored in browser history, server access logs, and potentially proxy caches, allowing a local attacker with access to the victim's browser history to recover valid login credentials.

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.
-
Verify Quick.cms versionCheck the installed Quick.cms version by inspecting the version file, admin panel 'About' section, or the main index file for a version constant. Compare your installed version against the affected version: 6.8Affected if Your installed version is exactly 6.8
-
Examine login form submission methodView the source code of the login form (typically in the main template or login include file). Look for the form tag and identify whether the method attribute is set to 'GET' instead of 'POST'Affected if The login form uses method="GET" or lacks an explicit method attribute (defaulting to GET)
-
Inspect URL patterns during loginAttempt a login with test credentials while monitoring the browser's address bar or using a proxy. Observe whether the username and password appear as URL query parameters (e.g., /login.php?username=test&password=test)Affected if Credentials are transmitted as URL query parameters (visible in the browser address bar after form submission)
-
Review server access logs for credential leakageExamine your web server access logs (Apache access.log, Nginx access.log, or similar) for entries containing the login script path with username and password parameters in the URLAffected if Server logs contain entries with credentials in the request URL (e.g., GET /login.php?username=...&password=...)
You are affected if you are running Quick.cms version 6.8 and your login form submits credentials via GET requests, exposing them in URLs, browser history, and server logs.

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 dataMigrate authentication from GET to POST requests, implement proper session token handling, and ensure credentials are never included in URLs or server log files. Users should avoid accessing the application from shared devices and clear browser history periodically.
