TITLE

InduSoft Web Studio 'CEServer' Component Stack Buffer Overflow Vulnerability

DESCRIPTION

Stack-based buffer overflow in CEServer.exe in the CEServer component in the Remote Agent module in InduSoft Web Studio 6.1 and 7.0 allows remote attackers to execute arbitrary code via a crafted 0x15 (aka Remove File) operation for a file with a long name. Authentication is not required to exploit this vulnerability.The flaw exists within the CEServer component which is used as a runtime dependency for applications deployed using Indusoft WebStudio. When handling the Remove File operation (0x15) the process blindly copies user supplied data to a fixed-length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the browser. InduSoft Web Studio is a powerful and complete graphics control software that includes tools for developing Human Machine Interface (HMI), Management Control, Data Acquisition System (SCADA) and embedded control. This vulnerability exists in the CEServer component. Successful exploitation of the vulnerability can be applied. Failed attacks will likely cause denial-of-service conditions. InduSoft Web Studio 6.1 and 7.0 are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-11-329 : InduSoft WebStudio CEServer Operation 0x15 Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-329 November 16, 2011 - -- CVE ID: CVE-2011-4052 - -- CVSS: 9, AV:N/AC:L/Au:N/C:P/I:P/A:C - -- 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 11473. - -- Vendor Response: Indusoft has issued an update to correct this vulnerability.
