TITLE

ISSymbol Virtual machine ISSymbol ActiveX Control buffer overflow vulnerability

DESCRIPTION

Multiple buffer overflows in the ISSymbol ActiveX control in ISSymbol.ocx 61.6.0.0 and 301.1009.2904.0 in the ISSymbol virtual machine, as distributed in Advantech Studio 6.1 SP6 61.6.01.05, InduSoft Web Studio before 7.0+SP1, and InduSoft Thin Client 7.0, allow remote attackers to execute arbitrary code via a long (1) InternationalOrder, (2) InternationalSeparator, or (3) LogFileName property value; or (4) a long bstrFileName argument to the OpenScreen method. Overly long to method bstrFileName argument. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Indusoft Thin Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within ISSymbol.ocx ActiveX component. When an overly large string is passed as the 'InternationalOrder' parameter, a heap overflow occurs. This vulnerability can be leveraged to execute code under the context of the user running the browser. InduSoft Web Studio is a powerful and complete graphics control software that includes the various functional modules required to develop Human Machine Interface (HMI), Management Control, Data Acquisition System (SCADA) and embedded control. The Advantech Studio ISSymbol ActiveX control handles boundary errors in the \"InternationalSeparator\" property. The Advantech Studio ISSymbol ActiveX control is prone to multiple buffer-overflow vulnerabilities because the application fails to perform adequate boundary checks on user-supplied input. Failed exploit attempts will likely result in denial-of-service conditions. Advantech Studio 6.1 SP6 Build 61.6.01.05 is vulnerable; other versions may also be affected. There are multiple buffer overflow vulnerabilities in InduSoft ISSymbol ActiveX control 6.1 SP6 Build 61.6.01.05 (ISSymbol.ocx 61.6.0.0) and other versions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-168 : InduSoft Thin Client ISSymbol InternationalSeparator Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-168 August 29, 2012 - -- CVE ID: CVE-2011-0340 - -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P - -- Affected Vendors: Indusoft - -- Affected Products: Indusoft WebStudio - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12446. - -- Vendor Response: Indusoft has issued an update to correct this vulnerability.
