{"vuid":"VU#484649","idnumber":"484649","name":"Microsoft Windows DNS Server vulnerable to cache poisoning","keywords":["Microsoft","Windows","Sever","DNS","spoofing","ms07-nov"],"overview":"The Microsoft Windows DNS Server is vulnerable to cache poisoning, which may allow a remote, unauthenticated attacker to cause a Windows DNS server to provide incorrect responses to DNS queries.","clean_desc":"Microsoft Windows DNS Server is a service that provides DNS serving capabilities for Windows 2000 server and Windows Server 2003. For a DNS server to trust a reply to a DNS request, the reply must contain the correct client source port and address as well as an identifier known as the transaction ID. Windows DNS server uses a predictable transaction ID generator, which can allow DNS cache poisoning.","impact":"A remote, unauthenticated attacker may be able to poison the cache of a Windows DNS server. This can cause client machines that use the DNS server to be redirected to malicious domains as the result of an incorrect DNS response.","resolution":"Apply an update\nThis issue is addressed in Microsoft Security Bulletin MS07-062.","workarounds":"","sysaffected":"","thanks":"This vulnerability was reported by Microsoft, who in turn credit Alla Berzroutchko of Scanit and \nAmit Klein\n of Trusteer.","author":"This document was written by Will Dormann.","public":["http://www.microsoft.com/technet/security/bulletin/ms07-062.mspx","http://www.trusteer.com/docs/windowsdns.html"],"cveids":["CVE-2007-3898"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-11-13T16:12:17Z","publicdate":"2007-11-13T00:00:00Z","datefirstpublished":"2007-11-13T19:28:28Z","dateupdated":"2007-11-13T19:32:26Z","revision":5,"vrda_d1_directreport":"0","vrda_d1_population":"4","vrda_d1_impact":"2","cam_widelyknown":"19","cam_exploitation":"0","cam_internetinfrastructure":"20","cam_population":"15","cam_impact":"2","cam_easeofexploitation":"10","cam_attackeraccessrequired":"20","cam_scorecurrent":"4.3875","cam_scorecurrentwidelyknown":"4.5","cam_scorecurrentwidelyknownexploited":"6.75","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":4.3875,"vulnote":null}
