CVE-2023-31406
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 · uneditedDue to insufficient input validation, SAP BusinessObjects Business Intelligence Platform - versions 420, 430, allows an unauthenticated attacker to redirect users to untrusted site using a malicious link. On successful exploitation, an attacker can view or modify information causing a limited impact on confidentiality and integrity of the application.
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 confidenceSAP BusinessObjects Business Intelligence Platform versions 420 and 430 contain an open redirect vulnerability due to insufficient input validation. An unauthenticated attacker can craft malicious links that redirect users to arbitrary untrusted websites, potentially leading to phishing attacks or credential theft.

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 SAP BusinessObjects BI Platform versionAccess the SAP BusinessObjects Central Management Console (CMC) or the BI Launch Pad about page to view the installed version numberAffected if The installed version is exactly 420 or exactly 430
-
Confirm web tier is deployedCheck if the SAP BusinessObjects web tier (BI Launch Pad or CMC) is accessible over HTTP/HTTPSAffected if The web interface is exposed and accessible to users
-
Review redirect-capable endpointsIdentify any web parameters that handle redirection or URL forwarding, typically found in login pages, logout handlers, or navigation linksAffected if Redirect parameters accepting user-controlled URLs are present in the web application
-
Test for unvalidated redirect behaviorObserve if URL parameters controlling redirect destinations (such as 'redirect', 'url', 'target', or 'dest') allow arbitrary external domainsAffected if The application redirects to URLs outside the expected domain without proper validation
A user is affected if their SAP BusinessObjects BI Platform installation is version 420 or 430 and has an exposed web interface with redirect parameters that do not validate destinations against an allowed list.

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 dataApply the relevant SAP security patch when available. Implement strict input validation and whitelist-based URL validation for redirect parameters to ensure only trusted destinations are allowed.
