The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks. La característica Web Proxy Auto-Discovery en Microsoft Internet Explorer 6 y 7, cuando un sufijo de DNS primario con tres o más componentes es configurado, resuelve nombre de host wpad no cualificado en un dominio de segundo nivel fuera de este dominio configurado en el DNS, lo cual permite a servidores WPAD llevar a cabo ataques de hombre en el medio (MITM, man-in-the-middle). • http://secunia.com/advisories/27901 http://support.microsoft.com/kb/945713 http://www.microsoft.com/technet/security/advisory/945713.mspx http://www.securityfocus.com/bid/26686 http://www.securitytracker.com/id?1019033 http://www.vupen.com/english/advisories/2007/4064 •

Stack-based buffer overflow in Microsoft msjet40.dll 4.0.8618.0 (aka Microsoft Jet Engine), as used by Access 2003 in Microsoft Office 2003 SP3, allows user-assisted attackers to execute arbitrary code via a crafted MDB file database file containing a column structure with a modified column count. NOTE: this might be the same issue as CVE-2005-0944. Un desbordamiento del búfer en la región stack de la memoria en Microsoft msjet40.dll versión 4.0.8618.0 (también se conoce como Microsoft Jet Engine), como es usado por Access 2003 en Microsoft Office 2003 SP3, permite a atacantes asistidos por el usuario ejecutar código arbitrario por medio de un archivo de base de datos de archivos MDB que contiene una estructura de columnas con un conteo de columnas modificado. NOTA: este podría ser el mismo problema que CVE-2005-0944. • https://www.exploit-db.com/exploits/4625 http://dvlabs.tippingpoint.com/advisory/TPTI-08-04 http://lists.grok.org.uk/pipermail/full-disclosure/2007-November/058531.html http://marc.info/?l=bugtraq&m=121129490723574&w=2 http://ruder.cdut.net/blogview.asp?logID=227 http://securityreason.com/securityalert/3376 http://www.kb.cert.org/vuls/id/936529 http://www.securityfocus.com/archive/1/483797/100/0/threaded http://www.securityfocus.com/archive/1/483858/100/100/threaded • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Microsoft XML Core Services (MSXML) 3.0 through 6.0 allows remote attackers to execute arbitrary code via the substringData method on a (1) TextNode or (2) XMLDOM object, which causes an integer overflow that leads to a buffer overflow. Microsoft XML Core Services (MSXML) versión 3.0 hasta 6.0 permite a los atacantes remotos ejecutar código arbitrario por medio del método substringData en un objeto (1) TextNode o (2) XMLDOM, lo que provoca un desbordamiento de enteros que conduce a un desbordamiento de búfer. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of various Microsoft software User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the substringData() method available on the TextNode JavaScript object. When specific parameters are passed to the method, an integer overflow occurs causing incorrect memory allocation. If this event occurs after a different ActiveX object has been instantiated, an exploitable condition is created when the ActiveX object is deallocated which can result in the execution of arbitrary code. • https://www.exploit-db.com/exploits/30493 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=576 http://secunia.com/advisories/26447 http://www.kb.cert.org/vuls/id/361968 http://www.securityfocus.com/archive/1/476527/100/0/threaded http://www.securityfocus.com/archive/1/476747/100/0/threaded http://www.securityfocus.com/bid/25301 http://www.securitytracker.com/id?1018559 http://www.vupen.com/english/advisories/2007/2866 http://www.zerodayinitiative.com/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •

The default configuration of Microsoft Windows uses the Web Proxy Autodiscovery Protocol (WPAD) without static WPAD entries, which might allow remote attackers to intercept web traffic by registering a proxy server using WINS or DNS, then responding to WPAD requests, as demonstrated using Internet Explorer. NOTE: it could be argued that if an attacker already has control over WINS/DNS, then web traffic could already be intercepted by modifying WINS or DNS records, so this would not cross privilege boundaries and would not be a vulnerability. It has also been reported that DHCP is an alternate attack vector. La configuración predeterminada de Microsoft Windows usa el Web Proxy Autodiscovery Protocol (WPAD) sin entradas WPAD estáticas, lo que podría permitir a atacantes remotos interceptar el tráfico web mediante el registro de un servidor proxy usando WINS o DNS y, a continuación, responder a peticiones WPAD, como es demostrado por Internet Explorer. NOTA: se podría argumentar que si un atacante ya tiene control sobre WINS/DNS, entonces el tráfico web ya podría ser interceptado mediante la modificación de registros WINS o DNS, por lo que esto no cruzaría los límites de privilegios y no sería una vulnerabilidad. • http://archives.neohapsis.com/archives/isn/2007-q1/0418.html http://isc.sans.org/diary.html?storyid=2517 http://news.com.com/Windows+weakness+can+lead+to+network+traffic+hijacks/2100-1002_3-6170229.html http://support.microsoft.com/kb/934864 http://www.vupen.com/english/advisories/2007/1115 https://exchange.xforce.ibmcloud.com/vulnerabilities/33244 • CWE-16: Configuration •

Stack-based buffer overflow in the AfxOleSetEditMenu function in the MFC component in Microsoft Windows 2000 SP4, XP SP2, and Server 2003 Gold and SP1, and Visual Studio .NET 2002 Gold and SP1, and 2003 Gold and SP1 allows user-assisted remote attackers to have an unknown impact (probably crash) via an RTF file with a malformed OLE object, which results in writing two 0x00 characters past the end of szBuffer, aka the "MFC42u.dll Off-by-Two Overflow." NOTE: this issue is due to an incomplete patch (MS07-012) for CVE-2007-0025. Desbordamiento de búfer basado en pila en la función AfxOleSetEditMenu en el componente MFC de Microsoft Windows 2000 SP4, XP SP2, y Server 2003 Gold y SP1, y Visual Studio .NET 2002 Gold y SP1, y 2003 Gold y SP1 permite a atacantes remotos con la complicidad del usuario tener un impacto desconocido (posiblemente caída) mediante un fichero RTF con un objeto OLE mal formado, lo cual resulta en la escritura de 2 caracteres 0x00 pasado el final de szBuffer, también conocido como "MFC42u.dll Off-by-Two Overflow". NOTA: este asunto es debido a un parche incompleto (MS07-012) para CVE-2007-0025. • http://www.securityfocus.com/archive/1/463009/100/0/threaded •
