CVE-2023-0023
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 · uneditedIn SAP Bank Account Management (Manage Banks) application, when a user clicks a smart link to navigate to another app, personal data is shown directly in the URL. They might get captured in log files, bookmarks, and so on disclosing sensitive data 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 Bank Account Management (Manage Banks) transmits personal data in plaintext URL query parameters when users navigate via smart links. This sensitive data gets recorded in browser history, server logs, bookmarks, and proxy logs, creating an information disclosure vulnerability.

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 installed SAP Bank Account Management versionAccess SAP transaction code SE11 or use transaction /n/BA1/FMB_BANK to view the system version information for the Bank Account Management componentAffected if The installed version is exactly 800 or 900 (these are the affected versions)
-
Determine if smart links are enabledCheck the SAP GUI configuration under Settings > Options > Smart Links, or inspect whether users have the ability to click smart links within Bank Account Management transactionsAffected if Smart links functionality is active and users navigate through bank records using this feature
-
Capture and inspect browser or proxy logsEnable browser developer tools or set up a proxy (e.g., SAP Gateway trace, web dispatcher logs) and navigate through Bank Account Management using smart links. Examine the captured URLs for personal data appearing as plaintext query parametersAffected if URL query parameters contain unencrypted personal data such as names, account numbers, or identification numbers
-
Review server-side logs for sensitive URL dataExamine SAP web dispatcher logs, ICM logs, or any reverse proxy logs for entries containing Bank Account Management URLs with query string parameters that include personal dataAffected if Server logs contain GET request URLs with sensitive personal information in the query string
You are affected if your SAP Bank Account Management is version 800 or 900 and users navigate via smart links, resulting in personal data appearing in plaintext within URLs captured in browser history, server logs, or proxy 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 dataImplement secure parameter handling by removing sensitive data from URL parameters - use session-based storage, POST navigation, or encrypted/hashed tokens instead of plaintext personal data in URLs.
