Description

SAP S/4HANA Finance (Advanced Payment Management) does not perform sufficient Cross-Site Request Forgery protection on certain requests due to this an attacker with low privileges could craft a malicious link or page. If an authenticated victim interacts with it, unintended actions could be triggered on the web server on their behalf. This results in a low impact on confidentiality and integrity. There is no impact on availability.

  "executiveSummary": "This vulnerability is identified as a Cross-Site Request Forgery (CSRF) flaw within the Advanced Payment Management component of SAP S/4HANA Finance.\nThe security weakness arises from insufficient request validation, allowing unauthorized state-changing operations to be performed on behalf of an authenticated user.\nAn attacker with low privileges can exploit this by enticing a victim into interacting with a crafted malicious link or web page.\nSuccessful exploitation results in unintended actions being executed on the web server, negatively impacting data integrity and confidentiality.\nThere is no reported impact on system availability.\nThe risk profile is primarily centered on the ability of an attacker to perform unauthorized transactions or administrative tasks using the session context of a legitimate user.\nExploitation requires the victim to possess an active authenticated session with the SAP application.",
  "technicalDetails": "The vulnerability resides within the SAP S/4HANA Finance Advanced Payment Management module, specifically stemming from a lack of robust anti-CSRF token validation or equivalent request verification mechanisms for sensitive operations.\nIn a standard web environment, CSRF occurs when a web application fails to differentiate between a legitimate user-initiated request and a malicious request forced by an attacker through the user's browser.\nBecause the application does not sufficiently validate the origin or integrity of incoming requests, the server-side logic trusts the incoming HTTP requests based solely on the presence of the user's existing session cookies.\nThe attack flow proceeds as follows: 1) An attacker crafts a malicious payload, typically embedded in a link or a hidden form on an external web page. 2) The attacker baits an authenticated user into visiting this resource while they have an active session within SAP S/4HANA Finance. 3) The browser, automatically including the user's session cookies, sends the forged request to the SAP server. 4) The server receives the request, identifies the valid session context, and executes the requested action without verifying that the request originated from the intended application UI.\nThe vulnerable component performs sensitive state-changing operations that are susceptible to these forced requests. An attacker with low privileges is sufficient to carry out this attack, as they do not need high-level access to the application themselves, only the ability to manipulate the user's interaction flow.\nPost-exploitation impact is characterized by unauthorized modifications to system data or the execution of business logic within the payment management workflow. Since the server processes these actions as if they were requested by the authenticated user, the integrity of financial records or payment configurations is compromised.\nThe scope of this vulnerability is limited to the specific end-points within the Advanced Payment Management module that lack CSRF protections. The vulnerability does not allow for cross-site scripting (XSS) or full remote code execution; rather, it allows for the unauthorized triggering of existing, legitimate web-based functions.\nNo specific network exposure beyond the standard web access to the SAP instance is required, and the exploit relies entirely on the client-side execution of a forged request."
