OPC servers are often used in control systems to consolidate field and network device information. The NETxAutomation NETxEIB OPC Server fails to properly validate server handles. This vulnerability may be triggered by an attacker with access to the server's OPC interface.","impact":"An attacker with access to the NETxEIB 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":"Apply a Patch or Upgrade\nNETxAutomation has released version 3.0.1300 of the NETxEIB OPC Server to address this vulnerability. NETxAutomation has also released a patch for NETxEIB OPC Server version 3.0 to address this vulnerability. Contact NETxAutomation for more information.","workarounds":"Restrict Access to the server Until a fixed version of the server can be deployed, we recommend restricting 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.","public":["http://www.neutralbit.com/en/rd/opctest/","http://neutralbit.com/advisories/NB07-22.txt","http://netxautomation.com","http://secunia.com/advisories/24612/"],"cveids":["CVE-2007-1313"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-01-12T18:20:39Z","publicdate":"2007-01-12T00:00:00Z","datefirstpublished":"2007-03-20T17:57:04Z","dateupdated":"2007-03-26T18:17:14Z","revision":24,"vrda_d1_directreport":"1","vrda_d1_population":"2","vrda_d1_impact":"3","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}
