Description

 SAP server-side Remote Function Call (aka RFC) API contains a flaw that may allow a malicious user to undertake a brute-force attack against accounts without inducing a lock-out. The issue is due to insufficient checking placed on the Remote Function Call API which can be used in place of the GUI for authentication. It is possible that the flaw may allow account compromise, resulting in a loss of confidentiality.

Classification

 Location: Remote/Network Access Required
Attack Type: Authentication Management
Impact: Loss of Confidentiality

Disclosure: OSVDB Verified

Solution

 Upgrade to SAP AP version 4.6e or higher (RFC Patch Collection 02 2003), as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
