SigPlus Pro ActiveX Control LCDWriteString() Method HexString Parameter Overflow

This script is Copyright (C) 2011 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has an ActiveX control that is vulnerable to
a buffer overflow attack.

Description :

The SigPlus Pro ActiveX control, used for electronic signature
integration with Topaz signature pads and installed on the remote
Windows host, is earlier than 3.95. A stack-based buffer overflow in
such versions reportedly allows execution of arbitrary code via an
overly long value for the 'HexString' argument to the 'LCDWriteString'
method.

Solution :

Upgrade to SigPlus Pro ActiveX version 3.95 or later as that is
reported to address this issue.

Risk factor :

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.4
(CVSS2#E:F/RL:W/RC:ND)
