TITLE

InduSoft Web Studio 'CEServer' Remote code execution vulnerability

Trust: 0.8

sources: IVD: 596a7eea-2354-11e6-abef-000c29c66e3d // CNVD: CNVD-2011-4895

DESCRIPTION

CEServer.exe in the CEServer component in the Remote Agent module in InduSoft Web Studio 6.1 and 7.0 does not require authentication, which allows remote attackers to execute arbitrary code via vectors related to creation of a file, loading a DLL, and process control. Authentication is not required to exploit this vulnerability.The flaw exists within the Remote Agent component (CEServer.exe) which listens by default on TCP port 4322. When handling incoming requests the process fails to perform any type of authentication. 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-11-330 : InduSoft WebStudio Unauthenticated Remote Operations Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-330 November 16, 2011 - -- CVE ID: CVE-2011-4051 - -- 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.
