CVE-2024-24552
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 session fixation vulnerability in Bludit allows an attacker to bypass the server's authentication if they can trick an administrator or any other user into authorizing a session ID of their choosing.
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 confidenceThis is a session fixation vulnerability in Bludit, a flat-file CMS. The flaw allows an attacker to pre-establish or force a session ID that a victim (such as an administrator) will then use. After the victim authenticates, the attacker can hijack the authenticated session by using the same session ID.

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 Bludit versionLocate the version file (typically version.php in the bl-kernel directory or check the admin dashboard for the version number)Affected if The installed version is 3.14.0, 3.15.0, or any version between them (>=3.14.0 and <=3.15.0)
-
Verify session ID regeneration after authenticationExamine the authentication code (typically in bl-kernel/ajax/login or similar login handlers) for session_regenerate_id() calls immediately after successful loginAffected if The code does not call session_regenerate_id() or equivalent after successful authentication, allowing the session ID to remain unchanged from before login
-
Test for session ID acceptance from user inputAttempt to set a custom session ID via a GET/POST parameter or cookie before authenticating, then authenticate and check if the same session ID is retainedAffected if The application accepts and maintains a session ID that was supplied or influenced by the user, rather than generating a fresh ID on login
You are affected if you are running Bludit version 3.14.0 through 3.15.0 and the application does not regenerate session IDs upon successful authentication, allowing session fixation attacks.
Generated from the published advisory. Verify against your own configuration.
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 dataThe standard remediation for session fixation is to regenerate (invalidate and create new) session IDs upon successful authentication. Additionally, session IDs should be validated and not accepted from user-supplied parameters.
