CVE-2024-43177
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 · uneditedIBM Concert 1.0.0 and 1.0.1 vulnerable to attacks that rely on the use of cookies without the SameSite attribute.
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 confidenceIBM Concert versions 1.0.0 and 1.0.1 fail to set the SameSite attribute on cookies, causing them to be sent with all cross-site requests. This enables attackers to potentially perform Cross-Site Request Forgery (CSRF) attacks or steal session credentials by tricking users into visiting malicious sites that trigger requests to the vulnerable IBM Concert instance.

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 IBM Concert versionCheck the installed version of IBM Concert through the web interface (typically in the About or Help section), command-line interface if available, or check product documentation/release notes that accompanied the installationAffected if The installed version is 1.0.0 or 1.0.1
-
Inspect cookie headers in HTTP responsesUse browser developer tools (Network tab), a proxy like Burp Suite, or curl -v to capture HTTP responses from the IBM Concert application. Look for Set-Cookie headers in the responseAffected if Any Set-Cookie header is missing the SameSite attribute (e.g., no SameSite=Strict, SameSite=Lax, or SameSite=None appears in the cookie string)
-
Verify SameSite attribute presenceExamine each Set-Cookie header returned by the application. The cookie should contain either SameSite=Strict, SameSite=Lax, or SameSite=None;Secure to be properly protectedAffected if The cookies returned by IBM Concert lack any SameSite specification and are sent with all cross-site requests
A user is affected if they are running IBM Concert version 1.0.0 or 1.0.1 and the application sets cookies without the SameSite attribute.

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 dataConfigure all cookies to include the SameSite attribute set to 'Strict' or 'Lax' (or 'None' with Secure flag if cross-site cookie usage is required), typically in the application server or web framework cookie configuration.
