{"vuid":"VU#926551","idnumber":"926551","name":"Takebishi Electric DeviceXPlorer OPC Server fails to properly validate OPC server handles","keywords":["Takebishi","OPC-SCADA","SCADA","control system","handle poisoning","OPC","DeviceXPlorer","INFO#111001"],"overview":"The Takebishi Electric DeviceXPlorer OPC server contains a vulnerability that may allow a remote attacker to execute arbitary code or cause a denial-of-service.","clean_desc":"OLE for Process Control (OPC) is a specification for a standard set of OLE COM objects for use in the process control and manufacturing fields. OPC servers are often used in control systems to consolidate field and network device information. The Takebishi Electric DeviceXPlorer OPC Server fails to properly validate server handles. This vulnerability may be triggered by an attacker with access to the server's OPC interface. The following versions of DeviceXPlorer OPC Server are affected by this vulnerability: DeviceXPlorer MELSEC OPC Server\nDeviceXPlorer SYSMAC OPC Server\nDeviceXPlorer FA-M3 OPC Server\nDeviceXPlorer TOYOPUC OPC Server\nDeviceXPlorer HIDIC OPC Server\nDeviceXPlorer MODBUS OPC Server\nRefer to Takebishi's Security Notice for DeviceXPlorer OPC Server for more information.","impact":"An attacker with access to the Takebishi Electric DeviceXPlorer OPC Server may be able to arbitrarily access server process memory, potentially allowing that attacker to execute arbitrary code or cause a denial-of-service.","resolution":"Upgrade\nTakebishi has released DeviceXPlorer OPC Server V3.12 Build3 to address this vulnerability. Refer to Takebishi's Security Notice for DeviceXPlorer OPC Server for more information.","workarounds":"Restrict Access to the server Restrict remote access to the server to only trusted hosts by using firewalls or only connecting them to private networks.","sysaffected":"","thanks":"This vulnerability was reported by \nNeutralBit","author":"This document was written by Jeff Gennari based on information from NeutralBit and Takebishi.","public":["http://www.faweb.net/us/opc/1231207.html","http://www.faweb.net/us/opc/","http://www.neutralbit.com/en/rd/opctest/","http://www.securityfocus.com/bid/23037"],"cveids":["CVE-2007-1319"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-03-14T13:28:57Z","publicdate":"2007-03-16T00:00:00Z","datefirstpublished":"2007-03-19T15:43:03Z","dateupdated":"2007-03-26T18:01:40Z","revision":36,"vrda_d1_directreport":"1","vrda_d1_population":"1","vrda_d1_impact":"2","cam_widelyknown":"5","cam_exploitation":"0","cam_internetinfrastructure":"10","cam_population":"5","cam_impact":"20","cam_easeofexploitation":"16","cam_attackeraccessrequired":"10","cam_scorecurrent":"4.5","cam_scorecurrentwidelyknown":"9","cam_scorecurrentwidelyknownexploited":"15","ipprotocol":"","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":4.5,"vulnote":null}
