{"vuid":"VU#361968","idnumber":"361968","name":"Microsoft XML Core Services XMLDOM substringData() buffer overflow","keywords":["Microsoft","XML Core Services","arbitrary code execution","ms07-aug","MS07-042"],"overview":"Microsoft XML Core Services contains an unspecified memory corruption vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.","clean_desc":"Microsoft XML Core Services (MSXML) allow developers who use JScript, Visual Basic Scripting Edition (VBScript), and Microsoft Visual Studio 6.0 to create XML-based applications. MSXML includes several ActiveX controls to allow XML support in Internet Explorer and other applications. The MSXML XMLDOM object contains a buffer overflow vulnerability in the substringData() method.","impact":"By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.","resolution":"Apply an update\nThis issue is addressed by Microsoft Security Bulletin MS07-042. This update provides updated versions of MSXML.","workarounds":"Disable ActiveX and Active Scripting Disabling ActiveX controls and Active Scripting in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the \"Securing Your Web Browser\" document.","sysaffected":"","thanks":"Thanks to Microsft for reporting this vulnerability, who in turn credit anonymous researchers working with Verisign iDefense VCP and Zero Day Initiative.","author":"This document was written by Will Dormann.","public":["http://www.microsoft.com/technet/security/bulletin/ms07-042.mspx","http://www.iss.net/threats/274.html","http://secunia.com/advisories/26447/","http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=576","http://msdn2.microsoft.com/en-us/library/ms755744.aspx","http://www.zerodayinitiative.com/advisories/ZDI-07-048.html"],"cveids":["CVE-2007-2223"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-08-13T14:59:56Z","publicdate":"2007-08-14T00:00:00Z","datefirstpublished":"2007-08-14T18:27:31Z","dateupdated":"2007-08-15T18:20:47Z","revision":9,"vrda_d1_directreport":"0","vrda_d1_population":"4","vrda_d1_impact":"4","cam_widelyknown":"15","cam_exploitation":"0","cam_internetinfrastructure":"13","cam_population":"18","cam_impact":"15","cam_easeofexploitation":"10","cam_attackeraccessrequired":"17","cam_scorecurrent":"24.0975","cam_scorecurrentwidelyknown":"28.400625","cam_scorecurrentwidelyknownexploited":"45.613125","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":24.0975,"vulnote":null}
