SAP SAPgui SAPIrRfc ActiveX (sapirrfc.dll) Accept Function Overflow

high Nessus Plugin ID 40618

Synopsis

The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.

Description

The remote host contains the 'SAPIrRfc' ActiveX control included with SAP GUI version 6.40 for Windows.

This control is reportedly affected by a heap-based overflow involving the 'Accept' method of 'IRfcServer' interface of the 'SAPIrRfc' control.

If an attacker can trick a user on the affected host into visiting a specially crafted web page, this issue could be leveraged to execute arbitrary code on the host subject to the user's privileges.

The existence of this vulnerability is confirmed in sapirrfc.dll version 4.0.2.4. Previous versions may also be affected.

Solution

Apply the patch for the control as described in the vendor advisory.
