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 · unedited
SAP Marketing (Contacts App) - version 160, allows an attacker with low privileges to trick a user to open malicious page which could lead to a very convincing phishing attack with low 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 · moderate confidence

SAP Marketing Contacts App version 160 contains an open redirect vulnerability where an authenticated attacker with low privileges can craft malicious URLs that trick users into visiting external phishing pages. The vulnerability allows manipulation of redirect parameters to bypass Same-Origin policy expectations, enabling credential harvesting through convincing phishing attacks with low confidentiality and integrity impact.

MitigationImplement strict validation and whitelisting of redirect URLs in the Contacts App, ensuring all redirect targets are verified against an approved domain list before redirection occurs. Apply canonicalization checks to prevent URL manipulation via encoding or domain spoofing.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if SAP Marketing is deployed
    Check your SAP system landscape for systems running SAP Marketing component. Query SAP transaction SM37 or use SAINT to list installed software components.
    Affected if SAP Marketing component is not present in the system.
  2. Determine SAP Marketing Contacts App version
    Use SAP transaction SPAM or SAINT to view installed software components and their versions. Look for component 'SAP_MKT' or 'SAP Marketing' and note the version number.
    Affected if The installed version is exactly 160.
  3. Verify Contacts App is accessible
    Check if the SAP Marketing Contacts App (transaction code often related to Marketing, typically accessed via Fiori Launchpad or transaction code like 'MDG_MKT_CONTACT' or similar Marketing transactions). Confirm the app is active in the system.
    Affected if The Contacts App is not deployed or accessible in the environment.
  4. Inspect redirect parameter handling
    Review the Contacts App configuration and any custom ICF (Internet Communication Framework) services related to redirect functionality. Use transaction SICF to check handler classes for redirect logic.
    Affected if The system shows redirect handlers that accept external URLs without strict domain validation.
  5. Check authentication and authorization
    Review if low-privileged users (with limited roles) can access the Contacts App and trigger redirect functionality. Use transaction SUIM to check role assignments.
    Affected if Users with low privilege roles (e.g., read-only or limited Marketing roles) can access the Contacts App redirect features.

A system is affected if it has SAP Marketing Contacts App version 160 deployed with the Contacts App accessible to low-privileged users and no validation on redirect URL parameters.
