CVE-2020-4675
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 InfoSphere Master Data Management Server 11.6 is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts. IBM X-Force ID: 186324.
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 confidenceIBM InfoSphere Master Data Management Server 11.6 is vulnerable to cross-site request forgery (CSRF). This allows attackers to trick authenticated users into unknowingly submitting malicious requests to the MDM server, potentially executing unauthorized actions such as data manipulation or configuration changes.

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 MDM Server versionCheck the installed version of IBM InfoSphere Master Data Management Server in the system information or about dialog. This is typically accessible via the MDM administrative console or by querying the server's version endpoint.Affected if The installed version is exactly 11.6 (the affected version)
-
Inspect anti-CSRF token configurationReview the MDM server configuration files and application code to determine if anti-CSRF tokens are implemented for state-changing operations such as data manipulation or configuration changes. Look for token generation and validation logic in the web application layer.Affected if Anti-CSRF tokens are NOT implemented or are missing for state-changing operations
-
Check SameSite cookie attributesExamine the cookie configuration settings for the MDM web application. Inspect HTTP response headers from the MDM server to identify if SameSite attributes are set on session and authentication cookies.Affected if SameSite cookie attributes are not set or are set to 'None' without the Secure flag on sensitive cookies
-
Review Origin and Referer header validationAnalyze the server-side request validation logic to determine if incoming requests to sensitive endpoints validate the Origin or Referer headers against a list of trusted domains before processing state-changing operations.Affected if Origin/Referer header validation is not performed or allows arbitrary origins
A user is affected if they run IBM InfoSphere MDM Server version 11.6 AND the server lacks anti-CSRF tokens, proper SameSite cookie settings, and Origin/Referer header validation for sensitive requests.

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 dataImplement anti-CSRF tokens for state-changing operations and configure SameSite cookie attributes. Additionally, validate Origin/Referer headers on sensitive requests to ensure they originate from trusted domains.
