The Manage Bank Statements in SAP S/4HANA does not perform required access control checks for an authenticated user to confirm whether a request to interact with a resource is legitimate, allowing the attacker to delete the attachment of a posted bank statement. This leads to a low impact on integrity, with no impact on the confidentiality of the data or the availability of the application.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
