Vulnerability from variot

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

    "data": "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-----\nHash: SHA1\n\nZDI-11-330 : InduSoft WebStudio Unauthenticated Remote Operations\nRemote Code Execution Vulnerability\nhttp://www.zerodayinitiative.com/advisories/ZDI-11-330\nNovember 16, 2011\n\n- -- CVE ID:\nCVE-2011-4051\n\n- -- CVSS:\n9, AV:N/AC:L/Au:N/C:P/I:P/A:C\n\n- -- Affected Vendors:\n\nIndusoft\n\n\n\n- -- Affected Products:\n\nIndusoft WebStudio\n\n\n\n- -- TippingPoint(TM) IPS Customer Protection:\nTippingPoint IPS customers have been protected against this\nvulnerability by Digital Vaccine protection filter ID 11473.
